Founding Engineer - Senior Software Engineer
We are a team of hackers building an AI Security Engineer: security automation that aims to match human-level performance in security code review. We are developing state-of-the-art AI Agents for cybersecurity and integrating them into autonomous systems. We're a 13-person team split between Poland (mainly Gdańsk) and San Francisco. We've raised $6M so far and are raising more. We're part of the NATO DIANA program and actively engaged in other NATO-related initiatives. Our clients operate in industries where cybersecurity isn't optional - it's mission-critical.
About the Role:
We are looking for a first-principles thinker who was very capable before AI and, with AI as a tool, is now even more dangerous. Someone who'll push our product forward, who leaves their ego at the door and works closely with the whole tech team to get results. Sometimes that means writing code end-to-end, sometimes it means weighing in on architecture and design decisions, or helping translate business requirements into technical language. Sometimes you'll be in the room with an enterprise customer, working through their needs directly. It's a genuinely varied, high-impact role - for both the team and the product.
What we offer
- 25,000–30,000 PLN net/month on a B2B contract + equity.
- A founding-engineer seat at an early-stage security & AI startup
- Remote, flexible hours, aligned to the Polish time zone.
- Direct, unfiltered access to the founders and the roadmap.
- Work that ships to real customers, fast - you'll see your code matter within weeks, not quarters.
- Health insurance and gym budget
- 6+ years of professional software development, most of it full-stack comfortably across TypeScript/JavaScript, React, Node.js, and REST APIs.
- Hands-on with microservices, AWS, Docker, and Kubernetes, and used to a real Git workflow - PRs, code review, the works.
- You've built things people actually use, not just things that pass a demo.
- You default to figuring it out - new tools, new domains - over waiting to be handed a spec.
- You'll push back on an idea if you think it's wrong, and you're just as happy to be pushed back on.
- Genuinely curious about LLMs in production.
- You're comfortable saying 'we shouldn't build this' or 'this approach is wrong' to a founder - and backing it up
- If you've only worked inside well-defined tickets with someone else deciding scope, this probably isn't the role for you
- Degree in Computer Science or a related field, or equivalent experience that gets the point across.
