• Create clean integration points for product modules built in native Android, React Native, Flutter, or WebView
• Partner with Product, Design, Backend, and Mobile engineers to ship high-quality consumer mobile experiences
• Improve Android app reliability, responsiveness, maintainability, and production quality across real-world devices
• Build observability and debugging workflows for crashes, app health, release quality, and user-impacting issues
• Define engineering patterns for native modules, cross-stack communication, hybrid screen ownership, testing, CI/CD, and rollout
• Use modern AI development tools to move faster while maintaining strong engineering quality

Qualifications

• 5+ years of professional Android engineering experience
• Strong hands-on experience with Kotlin, Android SDK, and production Android app development
• Experience building or owning major parts of a consumer-facing Android app
• Strong understanding of Android architecture, app lifecycle, navigation, concurrency, networking, persistence, dependency management, and modularization
• Experience building high-quality mobile UI using Jetpack Compose and/or the traditional Android View system
• Strong product sense and care for mobile user experience, polish, responsiveness, and reliability
• Ability to make independent architecture decisions and clearly explain technical tradeoffs
• Strong ownership mindset and ability to drive work end-to-end in a fast-paced environment
• Comfortable collaborating closely with Product, Design, Backend, Mobile, and Growth teams

Preferred Qualifications

• Experience leading or helping lead a team to build a mobile app from 0 to 1
• Experience working in a startup or high-growth consumer product environment
• Experience with React Native, including native modules, bridges, or hybrid mobile architecture
• Experience integrating Flutter or WebView-based modules into native Android apps
• Experience with Android performance profiling, startup optimization, memory management, UI responsiveness, crash reduction, or app health monitoring
• Experience with mobile observability and analytics tools such as Firebase Crashlytics, Sentry, Datadog, Amplitude, GA4, or similar tools
• Experience with feed-based, social, entertainment, creator, gaming, UGC, marketplace, or other high-engagement consumer products
• Experience with Gradle, CI/CD, staged rollouts, Play Console, app signing, and release automation
• Familiarity with iOS, TypeScript, React Native, Flutter, or web-based interactive content is a plus
