Job description

What we're looking for

• 2 to 5 years of professional software engineering experience, with meaningful time on customer-facing product work.

• You’ve built LLM-powered features, ideally in production for real users, and you can tell us how you knew they worked.

• Strong full-stack experience. Knowing software engineering fundamentals matters more than knowing the details of our stack.

• Product sensibility: you care about UX, speed and polish, and you push back when something doesn’t feel right.

• Comfortable without PM overhead: you shape the problem, not just the solution.

• Daily user of AI coding tools (Claude Code, Codex or similar) and enthusiastic about them as a way to build software.

• Rigorous about correctness and data handling.

• Fluent in English. Dutch is a plus, not a requirement.
