Overview
SENIOR QA ENGINEER — iOS & MOBILE AUTOMATION
We're looking for a Senior QA Engineer who is genuinely exceptional at automated testing on iOS — someone who can write Detox and XCUITest suites from scratch, reason about grey-box synchronization, and architect a test infrastructure that prevents regressions rather than just catching them. You'll own QA across our mobile (React Native / iOS & Android), web (React), and backend (API) surfaces, and you'll set the standard for how engineering ships with confidence.
Responsibilities
- Architect and maintain automated test suites for iOS (Detox, XCUITest), Android, web (Playwright/Cypress), and REST APIs — owning coverage end to end
- Write iOS automation that goes beyond happy-path flows: charge failures, 3DS challenges, subscription edge cases, deep-link state bootstrapping, and Keychain/AsyncStorage seeding
- Build and maintain a repeatable test infrastructure for payment scenarios (Stripe test mode, WireMock fixtures, sequential email generation) that eliminates false positives across parallel CI runners
- Configure and maintain GitHub Actions / Bitrise pipelines that boot specific iOS simulator versions, run suites in parallel, and collect video artifacts on failure
- Collaborate with engineering, product, and design to define testability requirements before features are built, not after
- Establish and document QA standards: contract testing (Pact/JSON Schema), flake quarantine policies, API response validation, and spy/mock/stub conventions across the stack
- Own bug lifecycle from identification to resolution — write precise technical artifacts for low-level failures (API payloads, native bridge call stacks, timing traces)
- Drive CI/CD integration so automated tests gate every PR and release, with per-test flake rate reporting over time
Who You Are
- 7+ years in software QA, with the majority of that time focused on mobile — specifically iOS automated testing
- Deep, hands-on expertise with Detox: you understand grey-box idle detection, can instrument custom native modules, and know exactly how to debug Detox synchronization failures on iOS
- Fluent with XCUITest, including accessibility identifier strategies, launch argument injection, and Keychain seeding for state bootstrapping
- Experience testing React Native and React applications — you know where the bridge is, how it fails, and how to spy on it without killing the network layer
- Strong command of mocks, stubs, and spies at the call-stack level: you can articulate when each is appropriate and write precise, non-brittle assertions against them
- Proven methodology for testing payment edge cases (card declines, capture failures, 3DS, network timeouts) repeatably on both simulator and physical device CI
- Solid experience with API contract testing (Pact, JSON Schema, or equivalent) — you've caught silent breaking changes before they hit production
- Strong understanding of flake detection, quarantine strategies, and async timing issues specific to iOS simulators
- Proficiency with bug tracking (Linear, Jira), version control (Git), and writing clear, low-level technical bug reports
- A precise, detail-oriented communicator who can write test plans as rigorously as they write test code
Bonus Points
- Exposure to performance, load, or security testing tooling
- Experience with Bitrise or GitHub Actions specifically for iOS simulator concurrency and artifact collection
- Familiarity with WireMock or similar HTTP stubbing for backend integration isolation
- Interest in fashion, luxury, or e-commerce
