Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed in 6-10 Weeks

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.

If you need full salary today, this is not for you. If you want to build something that actually matters and you're willing to bet on yourself for 6-10 weeks to get there — keep reading.

*Stack:* Python, Django 4.1, MongoDB, Flutter, Vertex AI (Gemini), Docker, AWS.

*Apply:* PeterJFrancoIII@gmail.com — Send your resume or GitHub and tell me what you'd ship in your first week.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

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.

Softmax | softmax.com | San Francisco (onsite) | Full-time

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.

Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.

I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.

Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.

The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.

If this sounds exciting, I’m looking forward to meeting you. E

What do y'all think about the latency/quality tradeoff with LLMs?

Human voices don't take 30 seconds to think, retrieve, research, and summarize a high quality answer. Humans are calibrated in their knowledge, they know what they understand and what they don't. They can converse in real time without bullshitting.

Frontier real time-ish LLM generated voice systems are still plagued by 2024 era LLM nonsense, like the inability to count Rs in strawberry. [1]

I'd personally love a voice interface that, constrained by the technology of today, takes the latency hit to deliver quality.

[1] https://www.instagram.com/reel/DTYBpa7AHSJ/?igsh=MzRlODBiNWF...

Not affiliated with Sesame, but this is what the realtime models are trying to solve. If you look at NVIDIA’s PersonaPlex release [0], it uses a duplex architecture. It’s based on Moshi [1], which aims to address this problem by allowing the model to listen and generate audio at the same time.

Di Rezze Family Office | AI-Native Technical Operations Lead | Miami, FL (ONSITE) | $130K-$200K + Early Equity | Full-Time

We're building an AI-native clinical data platform from the ground up, not a legacy system with AI bolted on. AI is core to the architecture, the development workflow, and the product itself. Fully funded by a private family office, no outside capital needed, no fundraising runway concerns. We're assembling the founding team now.

We're building a founding team to revolutionize healthcare in the United States, and we're hiring a technical operations lead. Best analogy: studio engineer to a recording artist. You own the environment so engineering leadership stays on high-leverage product work. That means CI/CD, QA, testing infrastructure, compliance documentation, and 30-40% independent feature development. Ground-floor equity in a company that's pre-revenue by choice, not by circumstance.

Hard requirement: you are already shipping software with AI coding tools daily (Claude Code, Cursor, Copilot, or similar). Not curious about AI. Not experimenting. Actively building and deploying with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit. Stack: React/Next.js, Python, PostgreSQL, Docker, AWS. But we care more about polyglot instincts than any single framework.

What we're looking for:

3-7 years full-stack experience Strong QA discipline (you write tests because you want to, not because someone made you) DevOps comfort: Docker, CI/CD pipelines, cloud infrastructure Self-directed. We don't micromanage and don't plan to start. Must be US-based or already have US work authorization. We do not sponsor visas.

What you get:

Meaningful early-stage equity (not a token option grant)

Direct access to founders and decision-makers, no layers

A say in the technical architecture from day one

Relocation to Miami fully covered

Health, dental, vision

Interview process: 15-min screen (show us your AI-built work) > take-home exercise > 2-hour paid working session > culture fit conversation.

Email: jpd@direzzefamilyoffice.com, subject line "HN March 2026" so I can find you.

Lead Full-Stack Engineer Marker Learning | Remote (U.S. only) | Full-time | Engineering | 185-250k

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)".

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

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.

Apex Dental Partners | Full-Stack Developer | Dallas, TX (Remote US or Hybrid) | apexdp.com

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.

  - 10+ years of experience. We need a "tinkerer" who understands math/physics and isn't afraid to poke at hardware.
  - Someone who thrives on "mission-critical" pressure. When a sculpture goes up in a public plaza, it has to work.
  - Mentorship-minded. You’ll help shape the software culture as we grow.

We aren't a typical art studio, our tech is state-of-the-art. You’ll work alongside ME's and EE's in our Brooklyn studio to build things experienced by millions. The role is primarily onsite in Brooklyn, but some flexibility can be discussed.

Deep Systems | Senior DevOps Engineer | Remote EMEA, APAC, and Americas | Full-time

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.

UTC-3 seems like a weird limit. UTC-2 and UTC-3 are basically just ocean. So the only real places that qualify are Buenos Aires and Coastal Brazil.

Also, not sure what the point of requiring that even is. There are plenty of candidates that would be willing to work those time ranges on the periphery. It's no different than getting an evening/graveyard shift at a domestic company, after all.

Hey, I would love to get into this position. Right now at my master's thesis I am researching something similar to this. I've just applied! Thanks for sharing the position.

Are you open to UTC -5?

Prequel | Software Engineers (backend or full-stack) | NYC (ONSITE) | $170k-$210k | prequel.co

Prequel enables software companies to sync data to their customers' data environments, at massive scale. With the rise of agents, syncing data to customers' data environments is becoming table-stakes for a lot of software companies. We make that incredibly easy for them.

We're a team of four engineers based in NYC. We're cash-flow positive and growing fast. We're solving a number of hard technical problems that come with syncing hundreds of billions of rows of data every day with perfect data integrity: building reliable & scalable infrastructure, making data pipelines manageable without domain expertise, and creating a UX that abstracts out the underlying complexity to let the user share or receive data. We're powering this feature at companies like Stripe (Metronome), Gong, Iterable, and more.

Our stack is primarily Golang/K8s/Postgres/DuckDB/React/Typescript and we support deployments in both our public cloud as well as our customers' clouds. Due to the nature of the product, we work with nearly every data warehouse product and most of the popular RDBMSs.

We’ve built a multi-agent coordination system that outperforms CC/Cursor at real research tasks, and are starting trials now with top-10 quant funds and AI labs.

We raised a $17M seed round led by Audacious and Conviction, with support from Bloomberg Beta, ex/ante, Wes McKinney (creator of Pandas), and several unicorn founders. Our team is composed of quants (ex-HRT, Citadel), PhD’s, and great founding engineers.

We’re hiring for high-agency engineers with sharp technical taste and experience in Python + React. We’d be particularly excited to meet full-stack folks with infra experience (distributed systems, cloud orchestration, etc) as we launch our cloud product.

Fractional AI | Senior/Staff Software Engineer | SF, NY, NC, Dubai | Onsite

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. You’ll work on 3-4 different projects a year and play a central role on each one. No AI experience required: we are actively trying to be the best place in the world to learn applied AI.

I’m Frank, an engineer here. This is the first services-style company I’ve worked at, so for those of you in a similar boat, this is what I’ve really liked so far:

* The learning rate is super fast. 3-4 client projects a year, each with different tech stacks, products, industries, and architectures.

* Our projects are typically high priority and sponsored by prominent executives. The path here for projects to have real impact on usage or bottom line is much shorter.

* We’re “selling pickaxes during the gold rush”. When AI finds its next killer app, we’ll hopefully be the first to know about it.

We’re hiring SWEs onsite with offices in San Francisco, New York, Durham NC, and Dubai. Feel free to reach out to me directly (frank@fractional.ai) or take a look at the full job posting:

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced software engineers for many roles. You can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Modelling buildings in code and finding the right UI for operators to edit them

- Designing systems for robots to drive safely and fully autonomously around a building site

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Constellation Finance | Multiple Engineering Roles | New York, NY | Hybrid | Full Time

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

SkySafe (https://skysafe.io) | Wireless Engineer (SDR) | San Diego, CA | ONSITE (Hybrid)

At SkySafe we build drone detection and tracking at scale.

I am looking for a Wireless Communications Engineer with SDR expertise to join my team - I'm the hiring manager.

I need someone with a very strong background in signal theory and experience building software wireless modems. You will spend time learning about new systems from our reverse engineers (no RE experience required!), implementing both open and recovered specifications, and refactoring existing modems code to improve it in both theory (ie - what is the algorithmic state of the art for demodulating xyz thing) and practice (ie - how much memory bandwidth and CPU are you using where). As such, I'm looking for someone with true software modem experience; while DSP, FPGA, and generated code experience are useful and relevant, you'll need to be able to read and write C++ directly.

I need someone who can come into the office in San Diego as needed to work with hardware, so this is a hybrid on-site role. This position requires access to technology which is controlled by US Export laws, so you also need to be an eligible US Person.

What we have to offer: $145-200k. Fun, small team dynamic. Work with experts in adjacent fields. Startup environment with good work-life balance and limited red tape. Rapid iteration and feedback in the wild. Good equipment at the office.

Apply: brian@ for a direct line, https://jobs.lever.co/skysafe for the formal route (we have some other roles I'm not the HM for listed there, too, if you're interested in the company!)

You will design delivery pipelines, build consent management workflows, architect Twilio integration layers, and handle the sharp edges that come with messaging at scale: retry logic, opt-out compliance (TCPA, A2P 10DLC), delivery optimization across carriers, and AI-driven message categorization.

You'll likely thrive here if you:

- 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.

RINSE | REMOTE or San Francisco, Los Angeles, Chicago, Boston, New York, New Jersey, Seattle, Austin, Toronto, or Washington DC | Software Engineer | Full-Time | Salary: $80k-$200k USD | https://www.rinse.com

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.

We're particularly interested in someone with significant React Native expertise at the moment, as we work to improve the apps our customers, delivery valets, and partners use.

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

Do you have offices in all those cities, or why are you listing them? I will downvote your and all other posts who do this unless you reply, because I think you are doing this to appear when people search for specific location.

We do have a physical footprint in each of those cities, and there is real value in being able to actually see our product and service in person by being in our service area. We can provide a desk with real co-workers in any of those cities.

See https://www.rinse.com/contact/#locations-heading

Most developers prefer to work from home, though! We're fully remote, and are free to mostly work from home or a co-working facility instead of one of our potentially-noisy offices.

Am I crazy if I hate remote?

I don't make the rules here, so I am going to remove the downvote, but I believe there should be a way to easily search for jobs that aren't remote.

I appreciate your response.

edit: I can't remove it anymore

Temper | Founding Engineer | SF (In-Person) | $150K–$250K + Equity | https://ontemper.com

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 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 looking for a founding researcher to lead our core research agenda. You will work at the intersection of representation learning, program synthesis, and efficient inference.

You will figure out how to teach models the latent physics of a codebase, the implicit architectural rules, dependency patterns, and style constraints that generalist models miss. Your work will range from designing new data engines to experimenting with novel architectures that break the memory wall of current transformers.

We are looking for someone with deep ML expertise (PhD or equivalent) who is code-fluent and comfortable writing kernels, not just training scripts.

Comper | Software Engineer #2 (Frontend focus) | €80-110k + equity | Utrecht, The Netherlands | ONSITE | https://comper.io

We make software landscapes understandable and explorable. Our canvas is zoom-to-code, and shows data on overlays from all of the git repos in your company. LLMs go through the codebase and extract the architecture.

We provide clarity when it's most needed: re-orgs, onboarding, explaining the tech stack at board meetings. Or just being stuck in your IDE and want to ask your team mate a question. We'd like to do to large org codebases what Figma did to design.

Comper needs someone that can build revolutionary UIs and go where no man has gone before. Our UI is the core of our product: a zoomable canvas that has all your code, documentation and diagrams on it. We have a long way ahead and need serious thinking to make sure we explain the software stack as simple as can be.

I'm the founder & CTO. We just raised a pre-seed and are now with 6 people. Find the vacancies on our site and send us an email.
