We are looking for a Mobile Game QA Engineer to join our team on a short-term project basis.

Identify FPS drops, memory leaks, crashes, and thermal/battery issues
Verify UI scaling, input responsiveness, and device compatibility
Stress test gameplay under heavy load and long sessions
Simulate poor network conditions (lag, packet loss, disconnects)
Check data sync, progression integrity, and recovery after reconnects
Log detailed, technical bug reports with videos, logs, and metrics
Requirements:
Experience in mobile game QA (preferably Android-heavy testing)
Strong knowledge of performance testing and device fragmentation
Familiar with network simulation and crash/performance tools
Ability to reproduce and document complex technical issues clearly
Experience with low-end devices and memory/performance constraints
