Responsibilities

Define app/module architecture (Clean, MVVM/MVI), boundaries, and data contracts; lead ADRs/design reviews; drive modularization and code health

Ship user‑facing features with maintainable Swift code; uphold code quality via reviews, automation, and guardrails

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.)

Optimize launch, frame time/dropped frames, memory, energy, and networking; apply Instruments and MetricKit; maintain 60/120 Hz frame budgets

Establish testability; write unit/integration/UI tests (XCTest/XCUITest, snapshot where useful); use URLProtocol/OHHTTPStubs for mocks; keep CI green

Implement Keychain/Secure Enclave, ATS, certificate pinning, and Biometric auth; own code signing/TestFlight, staged rollouts/feature flags; monitor crash/hang and drive RCAs

Required

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

Preferred

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
