Founding Engineer - Senior Software Engineer
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 you'll do
- Build prototypes and take them all the way into production - you own the messy parts too.
- Get requirements straight from our founders and the tech team, through real conversations, not a spec doc.
- Push product direction based on what users actually need, not just what's next on the roadmap.
- Own a product area end-to-end, from first idea to shipped feature.
- Team up with other teams to design, build, and test new features.
- Build on our core platform: Next.js, React, TypeScript, Tailwind CSS, Shadcn.
- Work on distributed, high-performance scanning systems on AWS&Kubernetes and help scale the infra for 10x the load.
- Push the state of the art in security automation - and be ready to defend the tradeoffs to product and business.
- Occasionally join customer calls to give GTM a technical read on what's needed.
- Optimizing our services for scalability, stability, and observability as our customer base grows and our product becomes more sophisticated.
- Helping our team define processes and practices that will serve us for years of growth and success.
Who you are
- 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.
Our stack
