Responsibilities

Define risk‑based coverage, entry/exit gates, and traceability; standardize test plans and device/OS matrices

Execute functional/regression/smoke/exploratory, cross‑device/browser, localization, and accessibility (VoiceOver/TalkBack) testing; reproduce issues and verify fixes

Build XCUITest/XCTest and Espresso/UI Automator suites (use Appium when cross‑platform is appropriate) and Playwright/Cypress for web; apply Page/Screen Object patterns, resilient locators, parallel runs, and flake control to keep CI green

Validate REST/GraphQL flows end‑to‑end (auth, payments, identity); employ mocks/stubs and contract testing where needed; inspect traffic with Charles/Proxyman

Measure startup, frame time/jank, memory/CPU/network/battery; track crash‑free sessions/ANRs; use Xcode Instruments, Android Profiler/Perfetto, and Crashlytics; collaborate on fixes and verify improvements

Validate real‑time WebSocket/streaming UI behavior (order lists, tickers), rate‑limit/backoff/reconnect handling, and precision‑sensitive workflows (prices/quantities/fees, deterministic rounding & idempotency)

Integrate tests into GitHub Actions/GitLab CI/Jenkins; run on device clouds (e.g., Firebase Test Lab, AWS Device Farm, BrowserStack) with artifacts (videos/screenshots/logs); manage test data and environment config; enforce merge/release gates

Produce concise dashboards and go/no‑go recommendations; support phased rollouts, feature flags/remote config, and post‑release monitoring

Preferred

Professional working proficiency bilingual in Mandarin

Contract testing (e.g., Pact), service mocking (MockWebServer, OHHTTPStubs), and feature‑flag‑driven testing

Validating analytics/event schemas and experimentation tags; data quality checks for real‑time feeds

Crypto‑domain: testing WebSocket/SSE flows, local state reconciliation after reconnects, precision/rounding verification with BigDecimal‑style logic, and auditability of user/account actions

Observability familiarity (logs/metrics/traces), synthetic monitoring, and basic SLO/error‑budget practices
