Mobile Engineer (iOS / Android)

About The Role The role focuses on building and shipping high-quality native mobile experiences for iOS and Android, used daily by hundreds of thousands of users. The engineer will own features end-to-end — from architecture and implementation through release, instrumentation, and iteration. This is a hands-on position on a mobile team that works closely with product, design, and backend engineers to ship user-facing products at a fast, reliable cadence, with real ownership over performance, reliability, and app store release quality. Key Responsibilities Design, build, and maintain native features in Swift/SwiftUI (iOS) and Kotlin/Jetpack Compose (Android), shipping through App Store and Play Store release cycles Architect and implement offline-first data layers, local caching, and sync logic against REST and GraphQL APIs Own cross-platform consistency: shared design system components, feature parity decisions, and platform-specific UX tradeoffs Instrument and improve app performance — startup time, render performance, crash rates — using tools like Firebase Performance, Sentry, and Xcode Instruments / Android Profiler Set up and maintain CI/CD pipelines for mobile using Fastlane, Bitrise, or GitHub Actions, including automated testing and staged rollouts Conduct thorough code reviews and contribute to team standards around modularization, testing, and release hygiene Collaborate with product and design to break down ambiguous feature requests into shippable milestones What We Are Looking For 3–6 years of mobile engineering experience, with deep expertise in at least one native platform (Swift/SwiftUI or Kotlin/Compose) and working proficiency in the other Track record of shipping and maintaining consumer-facing apps through multiple app store release cycles Strong understanding of mobile architecture patterns: MVVM/MVI, dependency injection (Hilt/Swift DI), modularization, and reactive programming (Coroutines/Flow or Combine/async-await) Experience integrating and debugging network layers against REST and/or GraphQL backends Hands-on experience with mobile CI/CD, automated testing (unit, UI, snapshot), and crash/analytics tooling Bachelor's degree in Computer Science or equivalent practical experience
