Zoolatech
Manual QA Engineer for Mobile App Central Europe
Zoolatech, Oklahoma City, Oklahoma, United States
Responsibilities
Own end-to-end QA within a sprint: create test strategies/plans, define scope & priority, estimate effort, track progress, unblock issues, and ensure on-time, high-quality releases. Plan and execute test cycles across feature, integration, regression, and release certification (TestFlight / Internal App Sharing / production). Author clear, reproducible defects with videos, logs, and device metadata; drive root cause and follow-through to resolution. Partner with developers & PMs to clarify requirements/acceptance criteria, risks, and success metrics. Network‑aware testing (airplane mode, 2G/3G throttling, packet loss) using proxies and emulator/simulator tools. Release readiness: build verification, smoke suites, sanity checks; participate in bug triage, go/no‑go, and post‑mortems. Automation‑aware: convert high-priority manual scenarios into actionable automation tickets; collaborate with SDETs on monthly audits and coverage plans. Lead release‑team testathons for major feature launches: plan charters, coordinate cross‑functional participants, track findings, and publish results. Work closely with the automation team on weekly release regression cycles: align scope, review flaky tests, and prioritize automation candidates from recent escapes. Hands‑on memory profiling using Xcode Instruments and Android Studio Profiler; detect leaks/retention, analyze heap/allocations, and file actionable performance bugs with traces. Be metrics‑oriented and deliver weekly Quality Release Reports to the Release Manager (coverage & pass rate, defect density/age/SLA, crash‑free users, ANR rate, cold‑start time, flakiness, known risks). Testing on real devices and emulators/simulators; coverage across OS versions, screen sizes, locales, accessibility setups. Qualifications
2+ years of hands‑on QA for iOS and Android consumer apps (feature, integration, regression, release testing). Strong understanding of SDLC and mobile release trains (feature flags, build types, staged rollouts, crash & analytics tooling). Clear, proactive communication—align with developers and product on requirements, test plans, and test strategies without supervision. Proven end‑to‑end ownership of sprint QA (scope/priorities, daily progress, blockers, timely sign‑off). Tooling: Xcode (logs, profiling), Android Studio/ADB, Charles Proxy or Fiddler, Jira. Manual REST API testing (Postman/Insomnia) and solid grasp of client–server interactions (headers, auth, caching). Excellent written/spoken English, crisp test docs and defect reports. Accessibility testing to WCAG 2.1 AA (VoiceOver/TalkBack, color/contrast, semantics). Experience with IAP/subscriptions, push notifications, deep links, geo features. Familiarity with crash/analytics stacks (Firebase, Datadog, Amplitude, Mixpanel, Sentry, Crashlytics). Exposure to mobile automation (XCUITest/Espresso/Maestro) and creating high‑value automation backlog. Client‑side performance profiling (startup time, memory, jank) and battery/network sensitivity checks.
