We build AI-powered mobile apps that reach millions of users worldwide.

We are a team of builders, designers, and engineers who move fast, take ownership, and create products used by millions.
About the Role
We’re looking for a Senior Android Developer to help us build and scale world-class mobile experiences.
You’ll work across our portfolio of AI-powered and consumer mobile apps, taking ownership from architecture decisions to production releases. You’ll solve challenging engineering problems, improve app performance, and help shape the technical standards of our mobile team.
What You’ll Do
- Build and maintain scalable, high-quality Android applications using Kotlin and Jetpack Compose
- Take ownership of the native Android layer in our Flutter apps, including architecture, integrations and platform-specific capabilities
- Build and ship Android-native features in our apps, such as home screen widgets with Glance, Live Updates and rich notifications, push notifications with FCM, Credential Manager and Sign in with Google, Google Play Billing and modern Material 3 experiences
- Bring AI capabilities to the native side where they make sense, using technologies such as ML Kit, on-device models with LiteRT, Gemini Nano through AICore, and Android speech and camera APIs
- Design and evolve maintainable Android architectures, reusable components and clear boundaries between native and Flutter layers
- Debug and resolve Android-specific production issues such as crashes, ANRs, memory leaks, performance regressions, networking problems and Flutter engine behavior on Android
- Profile and optimize app startup time, memory usage, rendering performance, battery usage and responsiveness using Android Studio Profiler and production monitoring tools
- Ensure our apps run reliably across the Android device ecosystem, including different OEMs, OS versions, screen sizes, tablets and foldables
- Improve engineering practices around testing, code review, CI/CD, release processes and mobile observability
- Act as the team's Android mentor by reviewing native code, writing internal guidelines, running knowledge-sharing sessions and helping our Flutter developers become confident on Android
- Keep a close eye on Android platform updates and Google Play requirements, such as target SDK deadlines and platform policy changes, and turn relevant developments into concrete technical and product proposals
