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.
