Test Engineer; Client

The Company:

Faraday Future (FF) is a California-based mobility company, leveraging the latest technologies and world’s best talent to realize exciting new possibilities in mobility. We’re producing user‑centric, technology‑first vehicles to establish new paradigms in human‑vehicle interaction. We’re not just seeking to change how our cars work – we’re seeking to change the way we drive. At FF, we’re creating something new, something connected, and something with a true global impact.

As a Staff Test Engineer (Client Applications) in our Crypto projects, you will own the end‑to‑end quality strategy and execution for iOS and Android apps and platform websites. You will translate requirements into scalable test plans and automation, architect and maintain mobile‑first and web/API test frameworks in CI/CD, and publish decisive, actionable quality signals. You’ll partner with Product, Design, and Engineering to drive design‑for‑testability, performance and reliability validation, and release readiness—focused on crypto use cases (real‑time data, account/KYC, payments, and secure integrations).

• Strategy & Governance:
  Define risk‑based coverage, entry/exit gates, and traceability; standardize test plans and device/OS matrices.
• Mobile & Web Testing:
  Execute functional/regression/smoke/exploratory, cross‑device/browser, localization, and accessibility (Voice Over/Talk Back) testing; reproduce issues and verify fixes.
• Automation Architecture:
  Build XCUITest/XCTest and Espresso/UI Automator suites (use Appium when cross‑platform is appropriate) and Playwright/Cypress for web; apply Page/Screen Object patterns, resilient locators, parallel runs, and flake control to keep CI green.
• API & Integration:
  Validate REST/Graph
  
  QL flows end‑to‑end (auth, payments, identity); employ mocks/stubs and contract testing where needed; inspect traffic with Charles/Proxyman.
• Performance & Reliability:
  Measure startup, frame time/jank, memory/CPU/network/battery; track crash‑free sessions/ANRs; use Xcode Instruments, Android Profiler/Perfetto, and Crashlytics; collaborate on fixes and verify improvements.
• Crypto Essentials:
  Validate real‑time Web Socket/streaming UI behavior (order lists, tickers), rate‑limit/backoff/reconnect handling, and precision‑sensitive workflows (prices/quantities/fees, deterministic rounding & idempotency).
• CI/CD & Environments:
  Integrate tests into Git Hub Actions/Git Lab CI/Jenkins; run on device clouds (e.g., Firebase Test Lab, AWS Device Farm, Browser Stack) with artifacts (videos/screenshots/logs); manage test data and environment config; enforce merge/release gates.
• Reporting & Release:
  Produce concise dashboards and go/no‑go recommendations; support phased rollouts, feature flags/remote config, and post‑release monitoring.

• Bachelor’s degree or above in Computer Science, Software Engineering, or a related discipline.
• 7+ years testing mobile and web applications, including 3+ years architecting/owning automation frameworks on a scale.
• Proficiency with XCUITest/XCTest and Espresso/UI Automator; exposure to Appium for cross‑platform scenarios.
• Strong web/UI automation with Playwright or Cypress and API automation using Postman/Newman or REST Assured; solid Type Script/JavaScript or Kotlin/Swift fundamentals.
• Deep understanding of mobile fundamentals: app/scene/activity life cycles, background limits (Doze/App Standby/BGTaskScheduler), deep links, notifications, permissions, and networking.
• Performance engineering:
  Instruments, Android Profiler/Perfetto, Crashlytics; ability to reduce cold start, jank, memory churn, and battery/network overhead.
• CI/CD at scale; device‑cloud operation; proven ability to stabilize flaky suites and optimize runtime.
• Clear written communication that turns into actionable risks and release decisions.

• Professional working proficiency bilingual in Mandarin.
• Contract testing (e.g., Pact), service mocking (Mock Web Server , OHHTTPStubs), and feature‑flag‑driven testing.
• Validating analytics/event schemas and experimentation tags; data quality checks for real‑time feeds.
• Crypto‑domain: testing Web Socket/SSE flows,…
