Senior manual qa engineer for mobile app
a large-scale consumer mobile application with millions of active users required a robust testing strategy to ensure stability, performance, and seamless user experience. Testing efforts focused on both ios and android platforms, covering functional validation, ui/ux consistency, geolocation features, and real-time interactions.
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).
5+ 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).
testing on real devices and emulators/simulators; coverage across os versions, screen sizes, locales, accessibility setups.
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.
