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, SwiftUI, 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 MetricKit; 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/TestFlight, 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, SwiftUI (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 URLSession, 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 MetricKit; ability to reduce cold‑start time, main‑thread blocking, memory churn, and dropped frames.
  • Networking/Security: strong with URLSession, 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 GitHub Actions/GitLab CI/Jenkins); ability to maintain stable, fast pipelines.
  • Professional working proficiency bilingual in Mandarin Chinese
  • Advanced Swift Concurrency and SwiftUI performance (state management, view identity, rendering); scalable modularization/componentization.
  • Media/Web content fundamentals (AVFoundation/AVPlayer, HLS/LL‑HLS, PiP/AirPlay; WKWebView performance for hybrid content).
  • Integration with major exchange/market-data APIs (REST + WebSocket), including local order-book maintenance (snapshot + delta, sequence handling), reconnect/backoff, and rate-limit strategies.
  • Precision-sensitive arithmetic for prices/quantities/fees using BigDecimal with deterministic rounding; idempotent client workflows for retries/status reconciliation.
  • Familiarity with wallet connection flows at the integration boundary (e.g., WalletConnect deep links/Intents) with safe isolation patterns and secure UX.
  • Building low-latency time-series charts on iOS (e.g., Swift Charts, Charts/DGCharts, SwiftUI Canvas/Core Animation/Metal) with frame-synced updates (CADisplayLink) and efficient diffing/decimation for live market data.
  • Healthcare + dental + vision benefits (Free for you/discounted for family)
  • 401(k) options
  • Casual dress code + relaxed work environment
  • Culturally diverse, progressive atmosphere
