Mix helps curious people discover, save, and share the best of the web through personalized, ad-free feeds across web and mobile platforms. We are seeking a mid-to-senior product-minded engineer to build polished user experiences across React Native, web, iOS, and Android.
In this role, you will primarily develop new mobile features in React Native while helping maintain and evolve existing native iOS and Android applications. You'll work closely with a small, agile team to turn user feedback and rough product ideas into fast, intuitive, high-quality experiences. This is a full-stack mobile and web role that requires strong product instincts, attention to UX detail, good design sense, and a bias toward shipping.
You should be comfortable working across the stack when needed, including APIs, native integrations, debugging, and existing Swift/Kotlin code. The ideal candidate combines strong React and React Native development skills with the ability to ship polished consumer-facing experiences across platforms.
REQUIREMENTS:
- Strong product-minded engineering skills with a track record of shipping polished consumer-facing experiences
- Solid UI/UX judgment and eye for interaction design, responsiveness, and visual polish
- Strong React Native, TypeScript, and React experience building production mobile applications for iOS and Android
- Strong modern web development experience with React, Next.js, Redux Toolkit/RTK Query or SWR, and Tailwind CSS
- Experience building and debugging React Native applications on real iOS and Android devices
- Experience integrating native device capabilities and platform APIs from React Native (deep links, push notifications, authentication, sharing, media, app lifecycle)
- Working knowledge of native iOS development with Swift, Xcode, Swift Package Manager, UIKit, and iOS app/extension targets
- Working knowledge of native Android development with Kotlin, Android Studio, Gradle, AndroidX, and Android application lifecycle
- Comfortable reading, debugging, and making targeted changes to existing Swift and Kotlin codebases
- Experience integrating APIs, analytics, crash reporting, and media-heavy user interfaces
- Able to debug real-device issues involving gestures, WebViews, video playback, navigation, performance, memory, responsive layouts, and iOS/Android differences
- Experience with modern AI-assisted development tools (Codex, Claude, Cursor, Antigravity, or similar)
- Collaborates closely with product and design to turn rough requirements into shippable, measurable product improvements
PREFERRED QUALIFICATIONS:
- Experience migrating or incrementally modernizing native iOS/Android applications with React Native
- Experience building React Native native modules, bridging native SDKs, or working with TurboModules/Fabric
- Experience with consumer social, content discovery, feeds, recommendations, sharing, or creator/community products
- Familiarity with Firebase, Segment, Branch, Sentry, Crashlytics, Airbrake, or similar analytics/observability tools
- Familiarity with common React Native libraries for navigation, server state, local persistence, media, gestures, animation
- Experience with native networking and media libraries (Retrofit/OkHttp/Moshi, Alamofire, Kingfisher, Glide/Coil)
- Strong eye for interaction details including gestures, transitions, animations, loading states, empty states, accessibility, device-specific polish
- App Store and Play Store release experience
- Experience with Fastlane, Bitrise, GitHub Actions, Docker, or similar CI/CD tooling
- Comfortable improving older native codebases without requiring full rewrite
- Writes maintainable code using appropriate testing and quality tooling (React Native Testing Library, Jest, Cypress, XCTest, JUnit/Mockito/Espresso, linting, type checking, formatting)
