About the role

  • Own quality across web and mobile frontends
  • Think like a real user with money on the line — hunt for edge cases, broken flows, and UX friction
  • Write and maintain automated test suites for the web app (Cypress, Playwright, or similar)
  • Test DeFi-specific flows — wallet connections, approvals, order types, transaction states, network switching
  • File detailed, actionable bug reports with reproduction steps engineers can immediately act on
  • Use browser dev tools and logs to investigate issues beyond surface-level symptoms
  • Work with engineering to verify fixes, catch regressions, and validate releases before they ship
  • Help build and improve CI-integrated test pipelines over time

Requirements

  • Solid experience testing web and mobile applications.
  • Familiar with DeFi primitives like wallets, approvals, order types, on-chain vs off-chain flows, network switching, transaction states.
  • You should be able to look at a trading interface and intuitively know what edge cases to hunt for.
  • Experience with automation testing on web apps (Cypress, Playwright, or similar), writing and maintaining test suites, not just manual passes.
  • Comfortable reading logs, using browser dev tools, and filing bugs that engineers can actually act on.
Benefits
