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.
Compensation & Benefits
Salary range: 80,000 to 120,000 EUR annually, plus equity options. A dedicated development budget, relocation support to Munich, and standard perks are also included. Visa sponsorship is not available.
Location
On-site in Munich, Germany.
