The role

You are the last line before players. Every game launch, every promo, every payment change goes through you, and ‘it worked on staging’ is not a result.

This is not a scripted-regression role. You decide what’s worth testing, build the automation that keeps it honest, and chase every issue until it’s actually dead.

What you’ll do

  • Own the test strategy across casino, sportsbook, PvP games, and live experiences
  • Build and maintain end-to-end automation that runs on every release
  • Test payment flows exhaustively — deposits, withdrawals, edge cases, failure modes
  • Verify game math against theoretical models: RTP, hit frequency, bonus triggers
  • Validate provably fair verification end to end from the player’s side
  • Triage production issues, reproduce them, and drive them to a fix
  • Improve the process, not just the ticket queue

What you’ll need

  • 3+ years in QA for web or mobile products, ideally gaming, gambling, or fintech
  • Strong automation skills — Playwright, Cypress, or equivalent, with real suites you maintained
  • You test payments properly: partial failures, timeouts, retries, double-submits, stuck withdrawals
  • Comfortable reading logs, network traces, and API responses rather than filing ‘it doesn’t work’
  • Understanding of RTP configs, bonus mechanics, and how a promo goes wrong
  • Crypto-comfortable. You can test a deposit flow without asking what a confirmation is.
  • Relentless. A bug you raised once and never followed up on is a bug you didn’t find.
