We're looking for a Senior Technical QA Tester to join the Idle Bank Tycoon team in Berlin. You'll own the quality of the game end-to-end: from feature testing and test automation to performance profiling and process improvement; embedded in a cross-functional team alongside Product, Game Design, and Engineering. If you enjoy both the technical depth of engineering and the craft of making sure things actually work for real players, this might be the right fit.

Own QA KPIs and drive continuous improvements to process and tooling
Requirements
Extensive QA experience in mobile gaming, ideally in an F2P/LiveOps environment
Hands-on experience writing and maintaining automated test scripts in Python
Solid understanding of mobile game performance metrics: profiling, memory, build sizes, and frame pacing on iOS and Android

Experience coordinating QA workload across internal and external testers
Familiarity with AI-assisted tooling for testing, triage, or workflow automation
