Founding Product Engineer

ABOUT THE ROLE This is the first engineering hire at a Y Combinator-backed AI marketing startup, working directly alongside the two founders. You will own full product features from ambiguous problem all the way to live, customer-facing product, and your work will span product thinking, frontend, backend, LLM pipelines, data, and direct customer conversations. It is a true founding-scope role with immediate, meaningful impact. WHAT YOU'LL DO - Own product features end to end: figure out what to build, ship it, and keep iterating until it creates real customer value. - Work closely with the founders and customers to turn conversations into concrete product improvements. - Build and maintain production full-stack features across frontend, backend, and data layers. - Design simple, intuitive UX for complex workflows. - Develop and improve LLM pipelines and agentic workflows within the product. WHAT WE'RE LOOKING FOR - Approximately 2 to 4 years of relevant engineering experience, with a strong track record appropriate for a first engineering hire. - Demonstrated early-stage startup or founding experience; big-company-only backgrounds are not a fit. - Has shipped products from 0 to 1 before and can independently deliver production-quality code. - Proficient with TypeScript and React; familiarity with Vite, Supabase, Vercel, or ClickHouse is a plus. - Comfortable working with LLMs and agentic workflows, both in the product and in day-to-day development (e.g., coding agents, MCP, or similar AI-leveraged tools). - Able to own full-stack product work from an ambiguous brief through to a live feature. - Communicates clearly and confidently with customers in English. - Experience in GEO, SEO, or marketing technology is a bonus. - Based in Munich or able to relocate readily. COMPENSATION & BENEFITS Base salary of EUR 85,000 to EUR 120,000 annually, plus equity participation (VSOP). Visa sponsorship is available. LOCATION On-site in Munich, Germany. Candidates willing to relocate are welcome to apply.
