We’re looking for a QA who owns backend quality: payments, subscriptions, and critical flows.
Not a checklist tester. You should understand where things break and catch issues early, ideally before they happen.

What you’ll be doing

• Test mobile apps (iOS) and web2app funnels
• Validate checkout flows and payments (end-to-end)
• Test backend APIs (payments, subscriptions, auth)
• Verify core functionality (UI, buttons, user flows)
• Work with webhooks and async processes
• Cover edge cases (failed payments, duplicates, delays, sync issues)
• Analyze logs and debug backend-related issues
• Write test cases and bug reports
• Perform regression testing before releases
• Write automated tests where needed

Requirements

• 4+ years QA experience
• Mobile (iOS) and/or web testing experience
• Strong experience with payments, checkout flows, subscriptions
• Backend / API testing (Postman, Swagger)
• Experience with:
  • webhooks / async flows
  • logs analysis & debugging
  • payment edge cases
• Understanding of:
  • client-server architecture
  • interaction between frontend, backend, and payments
• Ability to test end-to-end flows (user → payment → access)
• Automation experience (JS / Python / Java)
• Experience with Stripe or similar systems
• Basic SQL, CI/CD, event-driven systems

What we expect

• You think in funnels and user flows, not just screens
• You understand that QA impacts revenue
• You focus on edge cases, not only happy path
• You can work independently, solo and dig into systems
• You take ownership of product quality

What we offer

• Work on a real product with direct impact on revenue
• Ownership of backend and payment systems
• Remote work and flexible schedule
• Fast product iterations without unnecessary bureaucracy
• Strong product team and engineering culture
