You will work directly with product managers, designers, and backend engineers to ship features end-to-end, with real ownership over architecture decisions, release quality, and app performance. Key Responsibilities Build and maintain native iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) applications with a focus on performance, offline resilience, and clean architecture Ship features end-to-end: collaborate with product and design on specs, implement UI from Figma, integrate REST/GraphQL APIs, and deliver through App Store and Play Store release cycles Own mobile CI/CD pipelines using Fastlane, Bitrise, or GitHub Actions — including automated testing, code signing, staged rollouts, and crash-free release monitoring Instrument and monitor app performance using Firebase, Sentry, or similar tools; drive down crash rates, ANRs, and cold-start latency with measurable targets Write unit, integration, and UI tests (XCTest, Espresso, Compose testing) and maintain high coverage on critical user flows Participate in architecture reviews, code reviews, and mobile guild discussions; mentor mid-level engineers on platform best practices Contribute to shared component libraries and design system implementations to keep iOS and Android experiences consistent What We Are Looking For 3–6 years of mobile engineering experience, with deep expertise in at least one platform (iOS or Android) and working proficiency in the other Strong Swift and/or Kotlin skills; hands-on experience with SwiftUI and/or Jetpack Compose in production apps Experience consuming REST and/or GraphQL APIs, handling authentication, caching, and offline-first patterns Track record of shipping apps through the full App Store and Play Store release process, including review handling and staged rollouts Familiarity with mobile observability tooling (Crashlytics, Sentry, Firebase Performance) and fixing production issues from crash reports BS in Computer Science or equivalent practical experience building and maintaining consumer-facing mobile products Bonus: experience with cross-platform frameworks (React Native, Flutter), mobile security best practices, accessibility (WCAG), or contributing to open-source mobile libraries
