I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.

Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

Reach out directly with your resume and why you want this position to lucie@markerlearning.com. Make the subject "Lead Engineer Application (I am not a bot)".

Own the full stack for real: BGP/EVPN, transit, data center hardware, one of the world's largest Mac build fleets, and a private cloud spanning multiple locations — not just wiring up AWS components. Hybrid Linux/macOS environment, heavy Terraform/Ansible, usage. If blinking LEDs and routing tables get you going, this is the rare infra role where you can touch everything end-to-end.

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

We’re building an AI system that will disrupt the SaaS market as a whole. The foundation already exists and is running.

The concept itself is not difficult for experts once it becomes public, but the architecture and timing are key. We’re moving extremely fast.

Plan:

- release an open-source core - build a large community around it - scale fast enough to push competitors out

Current state is first friendly test customers onboarding in a few days. This is just 1 week old.

We’re currently reaching out to major AI labs since they could profit a lot from this, but we don’t need them to scale aggressively.

Right now there’s no significant funding yet, but the pace is extremely high and this could gain traction very quickly. We can likely raise ~€250k fairly quickly via public funding in my country, without giving up shares, but first we want to assemble the right people and make a plan together.

Looking for:

- someone with founder experience / VC contacts, or - hardcore AI engineers like me who ship extremely fast

We are currently EU-based, but the company can be set up wherever makes most sense for the business. It's huge fun to work with it.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

QuoIntelligence is a European cybersecurity threat intelligence company (~40 people, Series A, remote from Spain/Italy/German). We collect over 90% of our intelligence data in-house. No bulk feeds from Recorded Future or CrowdStrike. Custom pipelines scrape underground forums and ingest technical threat feeds, all built internally. The data engineering here produces the intelligence directly.

We are looking for someone to maintain and evolve the data infrastructure (built from scratch on DigitalOcean, no managed services, no IaC) while leading the migration to AWS and beyond.

Team is small and you'd be one of two data engineers, collaborating directly with Threat Intelligence Engineers on data access patterns and source integration.

I am building a DevOps team at a capital markets tech company most people haven't heard of — but some of the world's biggest financial institutions run on our platform. 300B+ messages/day. 99.99% uptime. Mostly on-prem, Linux, purpose-built hardware.

You'd be working on systems support, tooling, and helping build a custom observability platform in Python — because off-the-shelf monitoring doesn't cut it at this scale.

Capital markets / FIX experience is a plus, not a requirement. Appetite for learning is.

The vibe: small global team (US/APAC/EMEA), fully async, deeply technical. Leadership still codes. No hand-holding, no fluff.

Mainly focused on US and EMEA hires (we currently have people clustered in Belfast and North Macedonia); for APAC, we have solid leads. We don't have salary expectations to publish. We are open to different engagements given regional and your personal factors, including contract, W-2, contract-to-hire, etc.

Senior IC role, report to me directly.

Here's the problem: A small drone flies at you at 60mph / 100 km/h You have a camera, one edge processor, and must detect, classify, and track it at 30fps — against sky, trees, buildings. Starting from 100+ meters. If your pipeline drops a single frame at far range, the intercept fails. Sounds impossible? We think together we can solve this.

Now the second problem: Your guidance law needs to predict where that target will be in 0.5 seconds, compute the intercept geometry, and command the flight controller — with noisy IMU data, wind gusts, and a target that doesn't fly in straight lines. No GPS. No RF link. Just onboard compute.

We solved the guidance part in simulation. Our IBVS pipeline tracks and hits moving targets in SITL. The hardware prototype is built and ready. But the real engineering starts now.

We need:

* Computer Vision & Edge AI Engineer — YOLO on Jetson/Hailo/QRB5165. Detect, classify and track small targets at 100m+. Model pruning, TensorRT, sensor fusion. If you've pushed edge hardware to its absolute limits, this is your problem.

* GNC / Flight Systems Engineer — Image base visual servoing, proportional navigation, EKF/UKF state estimation, PX4 integration. Take what works in sim and make it survive real-world sensor noise.

* Simulation & Test Engineer — SITL/HITL, Monte Carlo campaigns, digital twins. 10,000 simulated engagements before anything leaves the ground.

* Technical Advisors — Drone warfare, GNC/aerospace, defense procurement. A few hours/month from the right person changes our trajectory.

We're a pre-seed defense startup in Munich building autonomous interceptor drones to stop FPV kamikaze drones. 2 founders. Salary + equity. No AI screening — we read every application.

We're a Dental Support Organization running 59 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.

Stack is primarily Rails 7.1 (Hotwire+Stimulus.js), with some React/Electron, C# .NET (OpenDental), and Go — all on AWS.

You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.

Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

Also we have our own in-house platform for the whole process, no pixel-pushing in Powerpoint here.

You'd join a small team of experienced founders and operators and help build features like onboarding, Stripe billing, org admin, and our agent. We're a small tech team, so you'd also help with CI/CD, lightweight DevOps, and AWS infrastructure.

Our current tech stack is simple and open to change: Laravel/PHP backend, alpinejs, mysql, and Bedrock on AWS.

You'll be successful in this role if you're a solid engineer and web developer, can read and write sql, and have some experience with tools and libraries like the ones we use--you needn't know exactly our stack.

Denver-based preferred. Competitive salary. Medical/dental/vision benefits, 401K match up to 4%. Sorry, no Visa sponsorship at this time.

For more about the job see https://truespace.com/careers/full-stack-developer/?njs and if that interests you, read more about TrueSpace and the team at https://truespace.com/ and please email us at careers@truespace.com with a resume and anything else that helps you show off what you can build.

Mobasi builds autonomous AI agents for digital forensics. Our software orchestrates 150+ forensic tools to help law enforcement turn days of manual evidence analysis into minutes, aiding in cases involving child exploitation, trafficking, and homicide.

Tech Stack: Rust, TypeScript, Python, Tauri, Next.js, Docker, Pulumi, Terraform.

We work as a small SWAT team. We are AI-native and expect you to use tools like Cursor and Claude to ship significantly faster. We do not have sprints or daily standups. Instead of lottery-ticket equity, we offer a high base salary and direct profit sharing.

At Constellation, we are building a future where technology is the lethal advantage in credit investing.

Credit documents govern everything from how much debt a company can incur, or pay in dividends, to what they can do with proceeds from selling assets. Hidden debt capacity, loosely drafted provisions, or ambiguous definitions can materially alter recovery, making precise covenant interpretation essential to investing outcomes.

Constellation makes it easy to read credit documents, calculate covenant capacity, and plan liability-management transactions, reducing the mechanical bottlenecks to analyzing credits and generating alpha.

Our team is comprised of subject matter experts who have spent a decade in credit (Goldman Sachs/Citadel), AI/ML researchers, and full-stack engineers who are dedicated to solving frontier problems in their application to the world's largest asset class.

We recently raised a $3.25mm round led by Haystack and Company Ventures. We are hiring for these roles: https://www.constellationfinance.ai/#/careers

- Have 5+ years building and scaling backend systems - Are strong in Ruby on Rails and Javascript with solid SQL chops

- Enjoy owning complex features end-to-end, from design through production support

- Think in terms of edge cases, failure modes, and delivery guarantees

- Want to mentor other engineers and shape technical direction

- Care about building infrastructure that has direct impact on patient outcomes

This is a senior role with shared team lead responsibilities. Small, mission-driven team with meaningful ownership. Equitable pay regardless of location.

Hey! I’m Maxim, cofounder/CEO of Immunera.

We're building blood tests that use gene sequencing and machine learning to help patients with autoimmune disease. Immunera spun out of years of research at Stanford, and our technology has been published in Science and covered by The New York Times.

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Spotlight roles:

* Engineering Lead

* Product Software Engineering (Quantitative Modeling)

Ongoing hiring:

* Bayesian Software Engineering

* Program Synthesis Engineering

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

We are building mobile products with a small, fast team and want a Flutter developer who is unusually strong at directing AI-driven software delivery. This is not a traditional "write the code yourself" role. We want someone who can decompose product and technical work clearly, set up coding agents and containerized environments so they can run independently, let them execute with very wide autonomy, and then use AI again to review, challenge, and validate the resulting commits. The standard here is technical excellence without manual coding as the primary lever. 100x engineering is the norm.

You might be a fit if you:

- are deeply experienced with Flutter and mobile product development

- are comfortable leveraging AI agents to plan, implement, test, and commit code with minimal guardrails

- can use AI-based review workflows to inspect commits, spot regressions, and maintain quality without doing line-by-line manual coding yourself

- have strong product and engineering judgment, and can tell when an AI-generated solution is structurally right vs. superficially plausible

- own and regularly use both a physical Android device and a physical iPhone/iPad for live app testing

- are familiar with provisioning, signing, installing, debugging, and validating Flutter apps on real devices, not just simulators

We care a lot about velocity, correctness, and taste. We are specifically looking for someone who can treat AI as the execution layer while still owning architecture, quality, release readiness, and real-device validation.

We read and respond to every application.

Every time two companies in the physical economy need to exchange data, someone builds a custom integration by hand. Analysts, engineers, QA. All manual. Every time. Google "EDI" if you haven't. It's wild.

We built AI agents that do the whole thing: gather requirements in plain English, write the integration code, test it, deploy it, fix it when it breaks.

We have paying enterprise customers and more demand than we can keep up with.

You'd be the first engineering hire. Agent orchestration, durable execution runtime, self-healing infra, most of the important architectural decisions haven't been made yet.

The founders built a logistics startup from pre-seed to 400+ people. We've been dealing with broken integrations for years.

Decise is a hands-on advisory and delivery firm that helps organizations unlock the full value of their technology and improve business profitability.

We work directly with executives to define what should be built, then we build it. Our work spans software engineering, data platforms, analytics, and customer-facing digital products. We often operate as fractional CIOs and CTOs, guiding both the strategic direction and the technical execution of our clients’ technology initiatives.

Our clients rely on us to turn complex business problems into working systems — not slide decks.

We are intentionally small and senior. Everyone on the team is a builder who can operate independently, solve complex problems, and deliver finished systems that people actually use.

White-glove service. Blue-collar grit.

We’re looking for a principal-level technologist who can move between engineering, architecture, and client strategy. Most of your time will be spent building systems and writing production code. The rest will involve working directly with executives to shape technical direction and ensure the work creates real business value.

Typical technologies we work with include React, Angular, Next.js, Node.js, Go, Snowflake, SQL, dbt, Domo, Streamlit, AWS, Vercel, and modern AI-assisted engineering tools. The exact stack varies by client; the ability to learn quickly and move confidently across technologies matters more than any specific tool.

Strong candidates typically have 10–15 years of experience building production systems and are comfortable operating both as hands-on engineers and as technical advisors to executives.

This is a long-term, full-time independent contractor engagement (1099). Everyone at Decise — including the founders — operates in this structure. Compensation is designed to be competitive with senior engineering roles at leading technology companies.

The fastest way to stand out is to show us something you’ve built: a production system, GitHub repository, application, or data platform you designed.

We are building an AI-powered civilian protection platform — real-time threat intelligence for non-combatants in conflict zones. Think Waze for airstrikes. Multi-model AI pipeline (Gemini) ingests OSINT, verifies it through gated analysis, and pushes geolocated alerts to offline-first mobile clients. People die when information is late or wrong — we are solving both problems.

We are currently unfunded, operating on sweat equity. Pre-seed is 6-10 weeks out. This is not a side project — we have a working system, a pipeline of 39 vetted applicants, and a founder who has been shipping code daily for months. But I will not sugarcoat it: right now, this is nights-and-weekends until funding closes.

*We need two people:*

*1. Systems Architect / Full Stack Dev* You see the whole board. You think in pipelines, failure modes, and deployment constraints — not just endpoints. You will own the technical architecture of a system where a bug isn't a bad UX, it's a missed warning. Python/Django, MongoDB, LLMs (Gemini/Vertex AI). Bonus: Flutter, OSINT, geospatial.

*2. Implementation Partner / Full Stack Dev* You ship. Relentlessly. You take a spec and it's done by morning. You don't wait for perfect — you build, test, push, iterate. Same stack: Python/Django, MongoDB. You will be the person who turns architecture into working product at startup speed.

Both roles require exceptional drive. This is a founding team — not a job listing.

*Compensation (No BS):* - *Now:* Sweat equity only. You're building your stake. - *Pre-Seed (6-10 weeks):* $3,000/month + equity per contributor. - *Seed (6-12 months):* 75% market salary + equity. Increases from there.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Our tech stack is Typescript, React, Next.js and Tailwind. On the backend we use Drizzle with Neon, deployed and monitored via Vercel. Please note that we are working in the CET timezone. We have pre-seed funding from a major US VC and are experienced founders. You’ll be working alongside the founders (ex-Apple, ex-Airbnb, ex-Tulip, ex-Tourlane) and will have a chance to shape the company, product and of course the engineering culture.

Innolitics builds AI/ML software for medical devices — the kind that detects ear infections, tracks metastatic cancer, and plans radiation therapy. 60+ FDA clearances. We need engineers who want their work to matter. We're a remote-only firm (since 2012) that does engineering, regulatory, and cybersecurity under one roof. Our team includes MDs, PhDs, and software engineers. Clients range from Series A startups to large device companies. We're hiring for three roles:

1. Physician-Scientist (MD/PhD) — Biostatistics & AI Software Development MD + PhD in biostatistics, bioinformatics, epidemiology, or a related quantitative field. You'll design biostatistical plans for AI validation studies (MRMC, standalone, prospective), build production-grade statistical software and data pipelines, write FDA-facing statistical sections, and analyze large clinical imaging datasets. Fluent in Python and/or R. This is not a pure research role — you'll ship code that gets FDA-cleared and deployed in clinics.

2. Senior Web/Mobile Medical Device Engineer 5+ years SWE experience. 3+ years each in web and mobile. Fluent in TypeScript and Python. You'll build medical device software and produce FDA-facing technical documentation. Cross-functional role bridging engineering and regulatory teams.

3. Medical Device Software Engineer 3+ years SWE experience. Fluent in Python, C++, or TypeScript. Heavier emphasis on software development initially; you'll grow into regulatory documentation work over time. All roles involve writing production code for medical devices, authoring documentation for FDA submissions, and working directly with clients. No prior medical device experience required — we'll teach you. Why engineers stay here:

Agentic AI tools (Claude Code, etc.) are part of our workflow. We treat them as a impact multiplier, not a threat. ~1 hour of meetings/week for ICs. Flexible hours. 2 hours every Wednesday dedicated to learning ("10x Time"). Healthcare-only revenue. No debt. Never had a layoff. We pay $300 for take-home exercises because your time has value.

Stack: Python, TypeScript, C++, R, Django, React, TensorFlow, PyTorch, scikit-learn, Qt, Terraform.

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.

We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

(If you have applied before, no need to re-apply, we’ll reach out.)

Support Engineer - If you want to use Claude or Codex (or Shelley!) to trawl through our code base, augmented with (carefully scoped) API keys to make our customers lives better, we are hiring.

Designer - If you want to use Claude or Codex (or Shelley!) to make our product functional and beautiful, we are hiring. You do not ship mocks or assets to other teams. There is no other team. You ship by pushing to production. Don't worry, we've got your back.

Software Engineer - If you see a pattern here, we are hiring. Expect to design, build, and run entire subsystems. What matters is attention to product detail and overall architecture, we have agents for writing code.

With significant industry experience, pay will be over $200,000 with meaningful equity.

We are a small team and going to stay one. The focus is building a high-trust environment. Success for us is if you say "I'm going to fix the load balancer" we all sigh with relief, because you are on it and we can rely on you to take on and solve large projects.

Empire Flippers is a true global-remote company with travel in our DNA and employees scattered across 5 continents and all sorts of countries. Since I joined 6 years ago, I've personally been to India, the US, Brazil, Ecuador, Colombia, Mexico, the Philippines, China, Japan, Thailand, the UAE, all while working remotely and coding our Ruby on Rails + React app. More about us here: https://empireflippers.com/about-us

Though not as well known in the Hacker News / venture-backed startups sphere, Empire Flippers is widely considered the #1 marketplace for buying and selling online businesses in the 5 to 8 figure USD range.

Think of businesses like --- that recipe site you landed on as the first result when you googled "best chicken tikka masala recipe". Or the Amazon FBA seller whose product you purchased when shopping for "Widget XYZ" (with Amazon FBA, these ecommerce businesses never touch inventory and so it's a fully online business).

Turns out these type of businesses may be earning 10s of thousands of dollars per month in profit (or more!) and when the (often first time) founder is ready to sell, Empire Flippers is the #1 place to do it safely, securely and at a fair market price.

Before I joined Empire Flippers I only had a peripheral understanding of this space, but now that I've been steeped in this industry I can say that this "mini M&A" world is just as exciting as the high-flying unicorns (and decacorns) that we read about daily on Hacker News.

The company is hiring for a few different positions (both technical & non-technical), all of which can be found here: https://empireflippers.com/careers

But in particular, I'm hiring a Ruby on Rails developer to help me continue to build out new features in our Platform, both for customers and to help run our (very extensive) internal operations of vetting incoming businesses, facilitating their sale, and migrating them to the new owner after they've been purchased.

That job ad can be found here: https://empireflippers.com/career/ruby-on-rails-developer/

As mentioned, we are a global-remote company that hires people of all nationalities located in any country in the world.

Hope to see your application soon, and with any questions feel free to email me (Ben) at beng at empireflippers.com

We are looking for candidates that are excited to join us on a mission to raise the standard of trust online. All of our roles are fully-remote, except where specific locations are noted.

Most of the software engineering positions have been repeating here for years because we've been continually hiring for them, scaling our whole team to now over 300 people—many of those hires have come through Hacker News. We've been improving our hiring process over time, and we know some good candidates may have fallen through the cracks. Some people who tried in the past have had success going through it again, and we still pay for hiring projects.

Hi! I work with a small group of developers doing custom software development and consulting for small/medium businesses.

We are seeking a developery-data person with experience specifically with CloudSuite Distribution by Infor for one of our clients. It may be a bit of a shot in the dark, but if you have worked with this *specific* ERP system before, we'd be eager to talk to you. Reach out at "ekib.eikooc@rofni".reverse() Please include your experience in your email body/subject as we will have to quickly triage out most of the spam.

PS. Each time I post here I get ~500 emails, almost all are low effort that don't meet anything I am looking for, sometimes for months in the future. I expect it to be even worse as LLMs gain traction. I've hired 4 people from past posts (check my history if you want!), but it can take some time dig through everyone so I apologize to legitimate interests.

Our initial cloud offering will be a fully managed backup service, secured with mandatory end-to-end encryption to ensure our users retain absolute privacy over their data.

We are seeking a versatile Senior Infrastructure & Platform Engineer who can work across the full stack of our cloud infrastructure, from bare-metal servers to the services running on them. This is a unique opportunity combining hands-on infrastructure work with platform and application-level development. You’ll be working in a small team to build our infrastructure from the ground up on our own hardware clusters while also contributing to the services and tooling that power our cloud offering.

To apply, send your resume and cover letter to jobs at futo dot org.

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

Charted Sea is a small, bootstrapped SaaS company helping customers scrape very complex platforms such as Shopee (a major e-commerce platform in Southeast Asia). We focus on hard technical problems (anti-bot, browser automation, fingerprinting, captcha solving).

We are hiring a senior engineer to take ownership of our core platform: scraper orchestrator, billing & payments, customer dashboard, and parts of our AI-based captcha tooling. This is a hands-on role with real ownership: architectural decisions, setting standards, and gradually mentoring other engineers. The role is very full-stack (infra, backend, frontend).

Stack includes TypeScript (most backend & web), Rust (new backend services, migration in progress), Go (Android scraper), PyTorch (captcha solvers), PostgreSQL, Redis, GitHub Actions, Ansible, Ubuntu Linux, bare-metal Hetzner servers.

We are profitable, demand is growing fast, and engineering bandwidth is the main bottleneck. Team is small (3 engineers), fully remote, mostly async (we expect ~4h overlap with UTC+8).

Compensation: $80k–$120k USD base (depending on experience) + monthly bonus tied to company revenue (10% of net revenue shared with employees).

Apply by emailing marc.plouhinec@chartedsea.com with a short intro and CV/GitHub. I'm the founder and will personally read and reply.

Not a job. I’m exploring alignment with a potential partner.

I’m a systems builder (CS/infra founder; shut down my last startup) who spent the past two years going deep on foundational math that most engineers (and I guess many mathematicians) tend to ignore, largely at an nLab level, because standard abstractions stop composing.

I’m working toward a small, private apply-focus lab to bridge native CS intuition (computation, scale, systems) with structural, information-theoretic mathematics. The focus is composability, learning, universality, and complexity, with the intent to build, not publish.

The approach is unconventional, but intentional: staying close to real systems while reworking foundations when existing methods stop composing.

Looking for a self-funded generalist comfortable crossing CS, math, and theory that's interested in structure, information, ethics, and long-horizon work.

We simulate materials at the atomic level for aerospace, defence, nuclear fusion, and advanced polymers. Our team of four built a near-comprehensive platform in the last year, we're the first to scale MLIPs across GPUs, and we're patenting our first new material now.

We're hiring multiple roles at the moment:

Chief Business Officer: https://atomictessellator.com/careers/chief-business-officer

Lead Engineer, Front-end: https://atomictessellator.com/careers/front-end-engineer

We're also taking expressions of interest, as we are always open to hearing from exceptional people. If you are intellectually curious, highly self-directed, and comfortable taking full ownership of problems end-to-end, you should apply, even if there is no current role that fits you exactly.

Design Engineer: https://atomictessellator.com/careers/designer-expressions-o...

Generalist: https://atomictessellator.com/careers/general-expressions-of...

Computational Materials Scientist: https://atomictessellator.com/careers/materials-scientist-ex...

Ideally you should be within +- 4 hours of UTC+12, unless very senior.

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.

Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.

We're open to both newly-graduated engineers or more senior engineers, provided they meet our bar. We're particularly interested in true full-stack engineers, with strong React / Typescript / CSS skills to complement comfort in a Python / Django environment. We're also seeking engineers with experience leveraging AI to automate complex operational processes.

You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.

Search term bingo: Logistics, Django, Python, Optimization, React, React Native, Postgres, Mobile Engineer, Automation, Delivery, OR-tools, Forecasting

We're focused on hiring developers that love the data ecosystem, are interested in really hard distributed systems problems, and working on dev tools.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.

We grew 4x in 2025 and anticipate similar growth in 2026. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

  *Flaky Tests: Detect and eliminate Flaky Tests.

Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is a chance to shape a new approach to knowledge representation from the ground up, working alongside a collaborative team driven to solve hard problems.

We’re hiring for the following openings:

* Product Software Engineering (Quantitative Modeling)

* Bayesian Software Engineering

* Program Synthesis Engineering

* Technical Project Manager

* Finance Manager - Corporate & Accounting

You’ll be working across the entire stack: from building customer-facing features in React and Django to architecting data pipelines that process petabytes of medical claims and rates. Crucially, this role involves deep algorithmic and analytical work. You won't just move data; you will implement the logic that makes sense of it.

We value "generalist" DNA—engineers who are as comfortable optimizing a SQL query as they are building a clean UI component. If you enjoy solving high-scale data problems that have a direct impact on healthcare affordability, we’d love to talk.

Tech: Python, Django, React, AWS (ECS, Step Functions, Athena), SQL (DuckDB/Polars), Iceberg/Redshift.

Return (https://return.energy) is hiring a software engineer to work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-scale Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will make a measurable, country-level impact on the transition to renewable energy. Return recently raised €300M to support its growth.

While we employ more than 120 people, Return’s technical team remains small with 13 members. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.

During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.

Your primary focus will be to further develop our battery virtualization platform, enabling customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.

Our tech stack and toolset are straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, and self-hosted plus cloud compute. We keep meetings to a minimum to provide at least five hours of uninterrupted coding time per day. We conduct code reviews and apply both automated and manual testing. Our web apps and platforms are often deployed multiple times per day.

Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss finances, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.

The tech team members have co-founded several companies and have worked with remote development teams since 2008, and they will personally guide you through most of the recruiting process (there is no recruiter involved).

We aim to hire you in February or March ultimately.

At xdof, we're at an inflection point. Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We're building the foundation behind the foundation models – the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain – to help our partners drive the field forward.

Founded by UC Berkeley Robotics PhDs and MechEs, this is a team that executes across software, hardware, and operations faster than I can believe sometimes. This speed and ability to deliver has led to partnerships with many of the top players in the space.

We are not quite yet out of stealth, so not able to share more details here, but are so understaffed relative to demand that I'd like to start semi-public hiring ASAP.
