Job Description

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.

Requirements

What You'll Do

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
