Founding Engineer

We're looking for a Founding Engineer to work directly with leadership on high-impact, zero-to-one projects. If you love taking full ownership, moving fast, and building real products end-to-end, we want to hear from you.

What you'll do

• Build core product features end-to-end (backend and/or mobile/web), from idea to production.
• Take full ownership of projects: scope, architecture, implementation, and rollout.
• Jump onto critical initiatives (SDK, network, new product bets) and unblock them fast.
• Ship high-quality, testable code at high speed.
• Work closely with whoever is needed to shape what we build next.
• Using AI tools (Claude, Cursor, Copilot, etc.) as part of your everyday toolkit — we actively encourage AI-assisted development.

What you'll need

• Strong experience as a senior-level engineer in product teams.
• Deep hands-on skills in backend (e.g. TypeScript/Node).
• Proven zero-to-one experience (early-stage startup, founding engineer, or similar).
• Track record of owning complex projects and delivering them to production.
• A builder with a strong ownership mindset and high output.
• Comfortable with ambiguity, fast decisions, and a high bar for quality.
• Product-minded: you care about impact, not just code.
• Clear communicator in English, both written and spoken.

What they offer

• Competitive package with meaningful equity.
• Central Berlin office with transport subsidy.
• Breakfasts and lunches provided.
• Language learning and Urban Sports Club access.
