## About the Role

* Several years of mobile development experience with shipped Flutter apps and real store releases behind you

 * You care about performance on mid-range devices, because that's what our users hold
 * Quality awareness and independent problem solving: you find the bug before support does

 * Based in Germany or Austria, or within two hours of that time zone

Great to have

 * Experience with real-time features: WebSockets, push, live data, audio

## Description

TikFinity Mobile runs on more than 500,000 phones. Creators use it to fire alerts and text-to-speech for their TikTok LIVEs straight from their pocket, and when it fails, it fails in front of a live audience. You build the app that doesn't.

We work AI-first. You build with Anthropic's Claude as a daily tool, which takes care of the routine work and leaves you the parts that need judgment: state, performance, background execution, and the edge cases that only show up when thousands of viewers send gifts at once.

You won't be alone with it. You join a larger development team, work day to day with the Product Owner who owns the mobile app, and share the codebase with a second mobile developer. Design hands you finished screens; your job is to make them real on both platforms.

Duties

 * Build and ship features for TikFinity Mobile in Flutter, on iOS and Android
 * Handle store releases together with your fellow mobile developer: submissions, versioning, crash monitoring
 * Turn finished screen designs into screens that feel right on both platforms
 * Keep the app fast and reliable while a LIVE is running: live events, audio, background operation
 * Work with the Product Owner and with developers from other product areas
 * Use Claude to speed up implementation, testing, and refactoring
