QA Engineer (Square)

Responsibilities

Own end-to-end quality for the Live Streaming & Content domain: requirements review → test planning → case design → execution → release sign-off

Lead cross-platform testing (App / Web / Backend / Admin), identifying E2E risk across the full stack

Drive live streaming feature testing: stream start/end, co-streaming, cross-room connections, playback, compliance — including edge cases like weak network, stream drops, backgrounding, and high concurrency

Maintain and extend our automation regression framework (Python + pytest + k6)

Collaborate closely with PMs, engineers, compliance, and operations to close quality loops fast

Contribute to AI-assisted testing initiatives and team knowledge base
