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.
