Description

Your Impact To support our mission, we’re looking for a Android Engineer with a strong focus on Android and Wear OS. In this role, you will take ownership of developing and optimizing smartphone and smartwatch applications, pushing the boundaries of system-level integration and user experience. You’ll collaborate closely with Product, Design, and Engineering to deliver seamless, high-impact features that make the Patronus watch even more powerful in supporting the independence and safety of elderly people worldwide. This is a unique opportunity to work both at the app and OS level — from building delightful consumer-facing apps to exploring system customizations that enable next-generation functionality. Your Mission Build and improve Android apps that delight users and enhance daily lives. Develop for Wear OS and Android smartwatches with seamless phone–watch synchronization. Dive deep into the Android system layer when needed: enabling root-level features, system integrations, and custom device behaviors. Explore and implement OS-level modifications, such as background services, optimized system processes, or device-specific enhancements. Optimize for performance, battery, and UX across mobile and wearable platforms. Collaborate cross-functionally with product, design, and engineering to bring high-impact features to life. Apply best practices for testing, CI/CD, and production monitoring to ensure reliability and scalability. Your Talent Strong track record in Android development using Java/Kotlin. Experience building both smartphone apps and smartwatch/Wear OS apps. Hands-on experience with Android system modifications (AOSP, custom ROMs, OEM integrations, root-level access). Solid understanding of low-level Android concepts like permissions models, system services, and background execution limits. Strong debugging and performance profiling skills — at both the app and system level. Nice-to-have: iOS (Swift) development experience. Knowledge of cross-platform frameworks (Flutter, React Native, KMP). Strong sense for UX/UI design. Exposure to health or IoT domains.
