Staff Software Engineer (iOS)

Faraday Future•Gardena, CA

81d

About The Position

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.

Requirements

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.

Nice To Haves

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.

Responsibilities

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.
