Full-Stack Product Engineer

Who you are

• You have around two to five years of professional experience building and shipping web or mobile products. What matters is what you've shipped, not the number
• You have 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
• You are comfortable across the stack, or comfortable on one side and genuinely curious about the other. We don't split frontend and backend here
• You ask questions early. On a team this size, saying you're stuck is more useful than working around it quietly
• You 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 and explain why the code does what it does
• You have experience with our stack, or you're willing to learn it: TypeScript, React, Next.js, React Native, Node.js, Postgres, Prisma
• Built AI product features (LLMs, agents, workflows, evaluation)
• Mobile experience, particularly React Native or Expo
• Worked somewhere small enough that you saw features go from idea to customer

What the job involves

• We're hiring a Product Engineer to join our product team in Berlin. This is a hands-on role for someone who wants to work across the whole product: the mobile app, the web app, and the API behind them. You'll ship to customers in your first week and be trusted with features end to end well before your first year
• 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
• You'll work extremely closely with:
• Emanuele (VP of Engineering)
• Feng, Çağatay (Senior Product Engineers)
• Yannick (Product Engineer)
• Ziar (Designer and Co-Founder)
• ...and often with Deniz (Co-Founder), who brings constant customer perspective
• This is a small, high-trust team. Low ego, high standards, lots of shipping
• You'll work directly alongside senior engineers who review your code and expect you to review theirs
