Mobile Engineer (iOS / Android)

About The Role

The role centers on building and shipping native mobile experiences used by customers every day - covering the full lifecycle from feature design and implementation to release management and production monitoring on both iOS and Android.

You will work directly with product managers, backend engineers, and designers to ship features in a fast-moving, well-funded environment where app quality, performance, and release velocity all matter equally.

Key Responsibilities

Build and ship user-facing features in Swift/SwiftUI (iOS) and Kotlin/Jetpack Compose (Android), owning them from design review through production rollout Architect clean, testable mobile codebases using MVVM or similar patterns, with modularization and shared business logic where appropriate Integrate REST and GraphQL APIs, implement secure authentication flows, and handle offline behavior, caching, and state management correctly Drive release quality: automated UI and unit tests, crash and ANR monitoring via Firebase Crashlytics or Sentry, and staged rollouts on App Store and Google Play Optimize app performance, startup time, battery usage, and bundle size using profiling tools like Xcode Instruments and Android Profiler Participate in code reviews, mobile architecture discussions, and CI/CD pipeline improvements (Fastlane, Bitrise, GitHub Actions) Collaborate with backend teams on API contracts and contribute to shared design systems and component libraries What We Are Looking For 3–6 years of mobile engineering experience, with at least 2 years shipping production apps on iOS, Android, or both Strong proficiency in Swift and/or Kotlin, including modern declarative UI frameworks (SwiftUI or Jetpack Compose) Hands-on experience with mobile architecture patterns (MVVM, MVI, Clean Architecture) and dependency management Track record of shipping apps through the App Store and/or Google Play, including release management and phased rollouts Experience with automated testing (XCTest, Espresso, Detox) and CI/CD pipelines for mobile Solid debugging skills across crash reporting, performance profiling, and network-layer issues; BS in Computer Science or equivalent practical experience Bonus: Experience with cross-platform frameworks (React Native, Flutter, KMP), app store growth tooling (feature flags, remote config, experimentation), or leading a mobile platform/infrastructure initiative
