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, spanning frontend, backend, LLM pipelines, and data. The role is genuinely foundational, with real influence over what gets built and how the product evolves. WHAT YOU'LL DO - Own product features end to end: scope, design, build, ship, and iterate until they create real customer value. - Work across the full stack including frontend interfaces, backend systems, LLM pipelines, and data layers. - Talk directly with customers, turn those conversations into product decisions, and represent the team well. - Design simple, clear UX for complex, multi-step workflows. - Use AI-native development workflows, including coding agents and MCP tools, as part of your day-to-day engineering practice. WHAT WE'RE LOOKING FOR - Approximately 2 to 4 years of relevant engineering experience, with a strong track record of shipping production SaaS features. - Demonstrated early-stage startup or founding experience; backgrounds limited to large companies are not a fit. - Has shipped a product from 0 to 1 before and can do so independently without a lengthy ramp-up period. - Proficient in TypeScript and React; familiarity with Vite, Supabase, Vercel, and ClickHouse is a plus. - Comfortable working with LLMs and agentic workflows, both in product features and in personal development tooling. - Strong communicator in English, comfortable speaking directly with customers. - Based in Munich or genuinely ready to relocate. - Background in GEO, SEO, or marketing technology is a nice bonus. COMPENSATION & BENEFITS - Base salary: EUR 85,000 to 120,000 per year. - Equity: VSOP grant included (range available on request). - Visa sponsorship: available. LOCATION On-site in Munich, Germany. Relocation support available for the right candidate.
