Jobbeschreibung

You build the subscription apps we ship under our clients' brands, from the empty repo to the App Store and every release after. Mobile, backend, billing, analytics: you work across all of it.

Our working language is English. You can work remotely across Germany.

Tasks

• Build cross-platform mobile apps in React Native and Expo, plus the backends behind them.
• Set up subscriptions and entitlements in RevenueCat and pass App Store review.
• Run live apps: ship changes, read the analytics, and fix what the numbers show.
• Make fast, clean technical calls in a small team.

Requirements

• You write strong TypeScript and have shipped mobile or web apps to real users.
• You build systems you can maintain, not prototypes you throw away.
• You work across the stack: frontend, API, and database. We use Next.js and Supabase.
• You write clearly. English is our working language.

Nice-to-have:

• React Native, Expo, or RevenueCat experience.
• You have kept apps running after launch.
• You work well alongside coding agents.

You join a small team where everyone touches the product. We keep communication short, decisions fast, and the work pragmatic: quick stand-ups, direct calls, clean code. The core team sits in Hamburg, and we work remotely across Germany.
