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).
experience
* 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.
