# Founding Product Engineer - Company: [Clera]() - Location: Berlin - Team: Engineering - Employment type: Full Time - Salary: €90K – €140K - Posted: August 26, 2026 ## Job description ### About the Role This is a founding-level engineering role at a fast-moving AI startup building an intelligent platform for strategic procurement. You'll work across the full stack — frontend, backend, and LLM integrations — shipping sophisticated agent-powered features directly used by enterprise customers. Your work will define how AI and procurement professionals interact at scale. ### What You'll Do * Build and ship full-stack features end-to-end, from UI through backend services to prompt workflows. * Prototype rapidly with LLMs and iterate based on real user feedback to refine product experiences. * Design and integrate agentic pipelines that make complex procurement intelligence feel simple and intuitive to users. * Translate signals from enterprise customers into well-scoped product experiences that land quickly. * Own prompt design, tuning, and LLM integration as a core part of the engineering work — not an afterthought. * Collaborate closely with the team in-person to move fast, make decisions, and build something exceptional. ### What We're Looking For * 1–10 years of professional software development experience; all levels considered — mindset and output matter most. * Strong proficiency in full-stack TypeScript across frontend and backend. * Demonstrated ability to work with LLMs: prompting, tuning, and integrating them into real products — shown through work, side projects, or hackathons. * Sharp product instincts and creative drive to build experiences users genuinely love. * High agency and outcome-oriented — you find a way forward without waiting for permission. * Comfortable navigating ambiguity and iterating quickly in a fast-moving, early-stage environment. * Eligible to work in Germany without employer-sponsored visa sponsorship. ### Compensation & Benefits Salary range: **€90,000 – €140,000 EUR annually**. Visa sponsorship is not available for this role. ### Location On-site in **Berlin, Germany**. Physical presence is required; remote work is not available for this role. ## Apply [Apply on Clera]() Canonical job page:
