Ensure analytics is correct: event naming, parameters, funnels, attribution consistency across platforms. Debug issues fast using logs + network traffic, provide clear repro steps and evidence.

Keep QA process lightweight but reliable: checklists/test cases where needed, strong bug hygiene in Jira. Collaborate closely with Product/Design/Engineering and help raise quality standards across the team.

What You Should Have

Middle+ / Senior QA experience in a product company. Strong hands-on mobile (iOS/Android) and web QA; healthcare and/or AI-enabled products is a plus.

Confident with tools: Xcode/Instruments, Android Studio, DevTools, Charles (or similar), Postman, Figma. Proven analytics validation experience (Amplitude / Firebase / AppsFlyer or similar).

Solid monetization testing background: IAP/subscriptions (states, renewals, cancellations), RevenueCat, and web payments (Stripe/PayPal). Web QA across landing pages, W2A flows, redirects/deeplinks basics. Understanding of Apple HIG and Material Design fundamentals. Strong Jira hygiene and clear test documentation (notes/checklists, bug reports).
