About The Position

The TikFinity Mobile app is used by over 500,000 creators to send alerts and text-to-speech messages for their TikTok LIVEs directly from their phones. This role involves building and maintaining an app that is reliable, especially during live events. The company utilizes an AI-first approach, with developers using tools like Anthropic's Claude for routine tasks, allowing them to focus on critical aspects such as state management, performance, background execution, and handling edge cases. The developer will join a larger development team, work closely with the Product Owner, and collaborate with another mobile developer. The primary responsibility is to translate finished screen designs into functional app features for both iOS and Android platforms.

Requirements

Several years of mobile development experience with shipped Flutter apps and real store releases behind you
Solid Dart, plus an understanding of the native iOS and Android layers underneath
Care about performance on mid-range devices

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

Nice To Haves

Basic mobile screen design skills for the cases where no finished design exists
A gamer, streamer, or content creator background
Experience with cloud providers like AWS or Hetzner

Work with the Product Owner and with developers from other product areas
Use Claude to speed up implementation, testing, and refactoring
