Key Responsibilities
- Build and maintain user-facing features in Swift/SwiftUI (iOS) and Kotlin/Jetpack Compose (Android), or with cross-platform frameworks such as Kotlin Multiplatform or React Native
- Design and implement mobile-first API integrations, handling auth, pagination, caching, push notifications, and background sync with graceful offline behavior
- Own app release cycles end-to-end: TestFlight and Play Console pipelines, staged rollouts, feature flags, and hotfix management
- Instrument and monitor app performance — crash rates, ANRs, cold start times, and frame rendering — using Firebase, Datadog, or Sentry, and drive fixes before users report them
- Write unit, integration, and UI tests (XCUITest, Espresso) and maintain CI/CD pipelines via GitHub Actions, Bitrise, or Fastlane
- Conduct code reviews, contribute to architecture decisions around modularization and dependency management, and mentor mid-level engineers
- Collaborate directly with product and design to translate specs into accessible, responsive interfaces that pass WCAG and platform accessibility guidelines
- 3–6 years of mobile engineering experience, with at least one app shipped and maintained in the App Store or Google Play at scale
- Deep proficiency in Swift or Kotlin, including modern declarative UI frameworks (SwiftUI or Jetpack Compose)
- Hands-on experience consuming REST and/or GraphQL APIs, local persistence (Room, Core Data, SQLDelight), and mobile security best practices
- Strong grasp of concurrency and async patterns: coroutines, actors, GCD, or Combine/Rx
- Experience with CI/CD for mobile builds and store deployments, including code signing and release automation
- Bachelor's degree in Computer Science or equivalent practical experience
- Bonus: Kotlin Multiplatform or Flutter experience, published open-source mobile libraries, or experience optimizing apps for low-end devices and poor network conditions
