Software Engineer; iOS

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 Software Engineer (iOS) in our Crypto projects, you will design, build, and ship high-quality iOS applications distributed via the App Store. You’ll own module-level architecture and end-to-end delivery—discovery, technical design, implementation, testing, performance tuning, release, and observability—using modern iOS practices (Swift, Swift

UI, structured concurrency with async/await/Actors, modularization with SPM). You will set engineering standards, lead design reviews, and partner with Product, Design, and Backend to deliver secure, fast, and reliable user experiences.

• Architecture & Design:
  Define app/module architecture (Clean, MVVM/MVI), boundaries, and data contracts; lead ADRs/design reviews; drive modularization and code health.
• Feature Delivery:
  Ship user-facing features with maintainable Swift code; uphold code quality via reviews, automation, and guardrails.
• Cross-Platform:
  Build and maintain Flutter (Dart) modules in an iOS “add-to-app” setup; integrate via Platform Channels/FFI; ensure UX/perf parity with native. (React Native experience is a plus.)
• Performance & Reliability:
  Optimize launch, frame time/dropped frames, memory, energy, and networking; apply Instruments and Metric Kit; maintain 60/120 Hz frame budgets.
• Quality & Testing:
  Establish testability; write unit/integration/UI tests (XCTest/XCUITest, snapshot where useful); use URLProtocol/OHHTTPStubs for mocks; keep CI green.
• Security & Release:
  Implement Keychain/Secure Enclave, ATS, certificate pinning, and Biometric auth; own code signing/Test Flight, staged rollouts/feature flags; monitor crash/hang and drive RCAs.

• Bachelor’s degree or above in Computer Science, Software Engineering, or a related discipline.
• 7+ years of professional iOS development with significant ownership of app/module architecture and delivery at scale.
• Expert in Swift, Swift
  
  UI (plus UIKit where appropriate), async/await/Actors, and modularization with SPM; solid DI patterns and testable architecture.
• App/Scene Lifecycle & System Fundamentals: deep understanding of App/Scene lifecycle, BGTaskScheduler/background URL Session, notifications, deep/universal links, multitasking;
  Core Animation pipeline and run loop basics.
• Performance Engineering: proficiency with Instruments (Time Profiler, Allocations/Leaks, Core Animation, Energy, Network) and Metric Kit; ability to reduce cold-start time, main-thread blocking, memory churn, and dropped frames.
• Networking/Security: strong with URL Session, caching, reachability, ATS, Keychain/Secure Enclave, privacy/ATT, and common auth patterns (OAuth2/OIDC).
• Flutter proficiency (Dart): capable of implementing production Flutter features, embedding Flutter reliably, integrating via Platform Channels/FFI, and profiling hybrid screens to meet frame budgets.
• CI/CD for iOS (Xcode/SCMs, Fastlane or Git Hub Actions/Git Lab CI/Jenkins); ability to maintain stable, fast pipelines.

• Professional working proficiency bilingual in Mandarin Chinese
• Advanced Swift Concurrency and Swift
  
  UI performance (state management, view identity, rendering); scalable modularization/componentization.
• Media/Web content fundamentals (AV Foundation/AVPlayer, HLS/LL-HLS, PiP/Air Play; WKWebView performance for hybrid content).
• Integration with major exchange/market-data APIs (REST + Web Socket), including local order-book maintenance (snapshot + delta, sequence handling), reconnect/backoff, and rate-limit strategies.
• Precision-sensit ive arithmetic for prices/quantities/fees using Big Decimal with deterministic rounding; idempotent client workflows for retries/status reconciliation.
• Familiarity with wallet…
