About the Role We're hiring a Manual QE Contractor to strengthen our release cycle across Trust Wallet's mobile apps (iOS + Android). You’ll work alongside our QE team on regression testing, bug triage, and release support — helping us ship higher‑quality mobile releases at a predictable cadence. This is a hands‑on, execution‑focused role: no automation coding required, but strong manual testing craft and structured bug reporting are essential. This is a contract engagement (initial 3–6 months, extendable based on fit and needs), remote, with working‑hours overlap with CET expected. What You’ll Do Execute regression test cycles on iOS and Android release candidates across our supported device matrix. File high‑quality bug reports with clear reproduction steps, environment details, logs, and severity rationale. Perform exploratory testing on new features and flows, surfacing edge cases the automated suite misses. Triage incoming bugs from internal dogfooding, production reports, and user feedback channels. Coordinate with developers and release managers during RC cycles — confirming fixes, verifying blockers, unblocking release gates. Maintain and extend manual test documentation (checklists, test cases, regression matrices) in our test management tools. Support release‑day validation including smoke tests on production builds and post‑release monitoring. Must Have 3–5 years hands‑on manual QE experience on both iOS and Android mobile apps. Strong track record with structured bug reporting — reproduction rates, device/OS matrices, logs, severity. Experience owning or supporting full regression cycles on a scheduled release cadence. Solid exploratory testing skills — session‑based, risk‑prioritized, documented. Familiarity with test management and bug tracking tools (TestRail, Xray, Zephyr, Jira, Shortcut, or Notion). Experience with real‑device testing via BrowserStack, Sauce Labs, or similar services. Excellent written English and async communication — contractors operate across timezones with written handoffs. Working‑hours overlap with CET business hours (at least 4 hours daily). Nice to Have Prior experience testing crypto wallets, DeFi, or fintech applications (or sensitive financial/user‑data products). Familiarity with browser extension testing (Chrome, Firefox, Brave). Comfort with basic log/network inspection tools (Charles Proxy, Xcode Instruments, Android Studio Logcat). Exposure to release management workflows and RC‑gating processes. Understanding of test pyramid concepts and where manual testing fits alongside automation. Additional Information This is a global and fully remote role.
