Product Engineer (Full-Stack)

Build and ship features across the mobile app, web app, and API. You'll work independently on features from spec through release, with direct access to operators and frontline users.

What you'll do

• Build and ship features across the app and the backend. Our mobile app is React Native, the web app is Next.js, and the API is Node and Postgres. You'll touch all of it.
• Work independently once you're ramped. You'll take features from spec through to release without close supervision, and stay with them after they ship.
• Fix what customers report. Bugs and customer-reported issues sit with the team that built the feature, and that includes you.
• Build internal tooling that empowers the sales and support teams to answer their own questions.
• Talk to the people using what you build. You'll have direct access to operators and frontline users, and we expect you to use it.

What you'll need

• Around two to five years of professional experience building and shipping web or mobile products.
• Product sense: you care about UX, clarity, and the details that make software feel right, and you bring ideas forward rather than waiting to be handed a ticket.
• Comfortable across the stack, or comfortable on one side and genuinely curious about the other.
• Ask questions early. On a team this size, saying you're stuck is more useful than working around it quietly.
• Work with agents and stay accountable for the output. We build with Claude Code and Cursor daily, and we care that you can tell good output from plausible output.
• Experience with our stack or willing to learn it: TypeScript, React, Next.js, React Native, Node.js, Postgres, Prisma.

Nice to have

• Mobile experience, particularly React Native or Expo
• Worked somewhere small enough that you saw features go from idea to customer

What they offer

• Work directly alongside senior engineers who review your code
• Design-focused culture where craft matters
• Direct customer access and real societal impact
• Berlin office with top equipment
