Requirements and responsibilities

Readable role content extracted into sections for faster review.

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

Requirements

  • 3+ years QA experience in internet / fintech / content platform companies
  • Live streaming testing experience (required) — you've tested stream start, co-streaming, push/pull streaming, interactive features, and playback end-to-end
  • Comfortable with agile release cycles (2–3 week sprints, grey rollouts, full releases)
  • Able to independently own test coverage and review others' test cases/code
  • Strong cross-functional communication — you proactively flag risk, not just report bugs
  • Python automation basics — read, extend, and maintain existing test scripts (no need to build from scratch)
  • Strong sense of ownership: you care about quality, not just coverage numbers

Bonus Points

  • Experience in Web3 / crypto / content community / fintech
  • Familiar with k6, JMeter, or other performance testing tools
  • API testing experience (Postman, packet capture, spec-driven)
  • AI-assisted testing or AI coding tools experience (Claude Code, Cursor, etc.)
  • Content moderation, anti-spam, or compliance testing background
  • SQL / data validation skills
