• Bonus: cross-platform tooling (React Native, Flutter) for internal tools.

Responsibilities

• Design, build, and ship native features across iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose).
• Own end-to-end feature delivery: design, implementation, testing, store release, and post-launch monitoring.
• Integrate with REST and GraphQL backend services, handling auth, caching, and offline behavior.
• Improve app performance and stability using profiling and crash analytics.
• Build and maintain CI/CD pipelines for mobile (Fastlane, Bitrise, GitHub Actions).
• Participate in code reviews, architecture discussions, and cross-functional planning.

Job description

About The Role

The role builds and maintains the native mobile applications that serve as the primary touchpoint for the product - covering the full iOS and Android stack, from UI implementation and offline data sync to deep linking, push infrastructure, and release engineering.

About The Role

The role builds and maintains the native mobile applications that serve as the primary touchpoint for the product - covering the full iOS and Android stack, from UI implementation and offline data sync to deep linking, push infrastructure, and release engineering.

You will work in a small, senior mobile team with direct input into architecture decisions, shipping biweekly releases to a growing user base where app performance and stability are treated as product features, not afterthoughts.

Key Responsibilities

• Design, build, and ship native features across iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose), maintaining parity across both platforms
• Own end-to-end feature delivery: technical design, implementation, testing, App Store / Play Store release, and post-launch monitoring
• Integrate with REST and GraphQL backend services, handling auth, caching, background sync, and graceful offline behavior
• Improve app performance and stability - reducing cold start times, memory footprint, and crash rates using Firebase Crashlytics and Xcode Instruments / Android Profiler
• Build and maintain CI/CD pipelines for mobile (Fastlane, Bitrise, or GitHub Actions), including automated testing, signing, and phased rollouts
• Participate in code reviews, architecture discussions, and cross-functional planning with product, design, and backend teams
• Instrument and act on analytics and crash data to drive prioritization of reliability and UX improvements

What We Are Looking For

• 3–6 years of experience building and shipping production mobile applications to the App Store and/or Google Play
• Deep proficiency in Swift/SwiftUI, Kotlin/Jetpack Compose, or both - with strong understanding of platform conventions and lifecycle management
• Experience consuming RESTful and/or GraphQL APIs and building resilient network layers (URLSession, Retrofit, OkHttp, or equivalent)
• Track record of owning releases end-to-end, including store submission, review processes, and hotfix workflows
• Solid grasp of mobile architecture patterns: MVVM, modularization, dependency injection (Hilt, Swinject, or similar)
• BS in Computer Science or equivalent practical experience
• Bonus: experience with cross-platform tooling (React Native, Flutter) for internal tools, mobile security best practices, or contributing to open-source mobile libraries
