Product Engineer

About the Role

This is a full-stack, end-to-end ownership role at a seed-stage construction tech company building agentic systems that bring real-time data and autonomous decision-making to some of Europe's largest contractors. You will not be a contributor on someone else's roadmap, you will own problems from first hypothesis all the way to a deployed, working product used by real customers in operationally complex environments.

What You'll Do

• Design, build, and ship complete autonomous agents that process documents, invoices, and supplier decisions in production environments.
• Own the full stack for your initiatives: agent logic, backend, frontend, and ongoing iteration with customers.
• Drive product areas such as procurement automation (requisition through posted invoice, fully autonomous) and contract visibility tooling.
• Identify opportunities to significantly expand platform value and execute on them with full mandate and support.
• Collaborate directly with customers to validate and refine solutions in the field.

What We're Looking For

• 3+ years of engineering experience in a high-growth startup or scale-up, with shipped products you owned end-to-end.
• Full proficiency in German and English, both spoken and written.
• Strong TypeScript skills in production systems.
• Proficiency with NestJS for backend development and React for frontend development.
• Experience designing and building autonomous or semi-autonomous systems.
• Demonstrated ability to take a product from zero to production deployment independently.
• Comfort navigating ambiguity and a track record of taking serious ownership.
• Familiarity with Flutter for mobile, GCP, or Hasura/GraphQL is a plus.
• Background in construction, logistics, or other operationally complex industries is a plus.
