About the Role
Kolibri Games is seeking a Senior Technical QA Tester to join the Idle Bank Tycoon team in Berlin. This role involves end-to-end ownership of game quality, including feature testing, test automation, performance profiling, and process improvement within a cross-functional team.
Responsibilities
- Own features and test coverage end-to-end, from identifying QA flows and edge cases based on product requirements to release sign-off and post-release monitoring of the game.
- Design, write, and review test plans and test maps; review submissions from other QA team members and define the QA strategy for complex features.
- Write and maintain automated test scripts in Python within our in-house Test Automation Platform; monitor branch runs and enforce sanity checks on release.
- Perform technical QA analysis, including runtime profiling, memory analysis, CPU/GPU usage, and build size validation on iOS and Android.
- Monitor and investigate regressions: frame rate drops, load time increases, APK/IPA size changes across builds.
- Coordinate team playtests and game releases; oversee QA workload and priorities across internal and external testers.
- 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 with test management tools (Xray, TestRail, Zephyr or similar) and Agile/Scrum workflows in Jira.
- Experience coordinating QA workload across internal and external testers.
- Familiarity with AI-assisted tooling for testing, triage, or workflow automation.
- Strong communicator in English (written and verbal) across cross-functional teams.
- Proactive, ownership-driven, and comfortable making calls in ambiguous situations.
