Founding Engineer

As a Founding Engineer, you sit at the intersection of product ownership and technical leadership. You'll take customer problems all the way from discovery to production while helping set the technical direction, practices and culture of the engineering team as we scale.

What you'll do

• Own product areas end-to-end: talk to customers, decide what's worth building, design the solution, and ship it across the stack.
• Work at the intersection of AI, complex data and thoughtful interfaces — building agent-powered features people rely on.
• Contribute to shared technical foundations — context handling, tool use, evaluations — that make the whole team faster.
• Set technical direction and raise the engineering bar as one of the first engineers on the team.
• Help shape team culture: how we hire, review code, communicate, and hold the bar on quality while shipping fast.
• Move fast without breaking trust: ship daily, learn from real usage, and keep raising the standard.

What you'll need

• You've personally shipped and owned production software for real users, ideally end-to-end.
• Strong engineering foundations across frontend, backend and databases; our stack is TypeScript, React/Next.js, Postgres/Supabase, Vercel and Python.
• You've taken on ownership beyond code — technical direction, process, or team practices — at a small or early-stage team.
• You use AI tools with curiosity and the technical judgement to verify what they produce.
• You communicate clearly, take initiative, and enjoy figuring things out directly with customers and teammates.

Nice to have

• Experience with LLM-powered systems or agent execution (tool use, context management, evaluations, sandboxes, building harnesses, orchestrating subagents, ...).
• Prior experience as an early or founding engineer at a startup.
• Procurement, enterprise SaaS or B2B data-heavy product experience.

What they offer

• Competitive salary and meaningful equity.
• Berlin, in person at Delta Campus, Berlin Neukölln.
• Direct collaboration with the founders and real influence over both product and company.
