Zoolatech

The partner is one of the largest retail e-commerce companies in North America. 
The team is working with the set of services that are used daily by external users. Though, in scope of the cloud transformation, we aim to increase scalability, improve performance, cost, and security. In order to do this, we are rebuilding the ecosystem: some legacy services will be replaced by the new ones which will be built with a modern approach (k8s, AWS, Kafka). 
Overall, if you like to communicate with customers and explore how things work at complex infrastructure, this might be the right project for you

Project Description

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.

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.
• API validation for mobile backends (manual REST verification, contracts, edge cases).
• Data/analytics validation (events, funnels, attribution) against tracking specs.
• 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).

Skills Required

Must-Have 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).
• 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, Qase | AI-powered Test Management Software for Quality Assurance .
• 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).
  
  Nice to Have
• 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.
