ABOUT THE ROLE

Full job description

ABOUT THE ROLE Join an early-stage AI procurement software team as a full-time Founding Engineer. You will own customer problems from discovery through production, build AI-enabled workflows, and help shape the technical direction and working practices of a small engineering team. WHAT YOU'LL DO

  • Build and ship full-stack product features based on customer needs, from initial discovery through production release.
  • Develop agent-powered workflows and shared foundations for context, tool use, evaluation, guardrails, and observability.
  • Make architectural decisions across frontend, backend, and infrastructure, considering performance, security, and developer experience.
  • Review AI-assisted code and use frequent releases and customer feedback to improve product quality.
  • Contribute to engineering practices, hiring standards, and team processes while working hands-on as an individual contributor. WHAT WE'RE LOOKING FOR
  • At least 3 years of experience building and shipping end-to-end product features across frontend, backend, and infrastructure.
  • Evidence of strong engineering ability, such as shipped products, technical leadership, open-source work, or other substantial accomplishments.
  • Production experience with TypeScript and Python, and experience building and deploying applications with React and Next.js.
  • Hands-on experience with production LLM applications, retrieval systems, and embeddings, including trade-offs across latency, cost, and quality.
  • Experience designing reliable LLM workflows with evaluation loops, guardrails, and observability.
  • Strong foundations in databases, APIs, and full-stack architecture; experience with PostgreSQL, Supabase, Vercel, REST or GraphQL, and real-time data integrations is relevant.
  • Startup or entrepreneurial product-building experience is valued, as is familiarity with procurement, ERP, or enterprise supply chains.
  • Clear communication, high agency, sound judgment, and comfort working closely with a team in person. COMPENSATION & BENEFITS Competitive salary and meaningful equity. Visa sponsorship is not available. LOCATION On-site in Berlin, Germany.
