Role Description As an Android Developer, you focus on building robust, secure, and highly-available server-side systems and APIs that power products, working closely with front-end engineers and architects to ensure performance benchmarks are consistently met. What We Expect From You: - Develop and maintain native Android applications in Java, writing clean, well-structured code that follows platform conventions. - Build intuitive, accessible user interfaces following Material Design principles using XML layouts or Jetpack Compose. - Integrate back-end RESTful APIs using Retrofit and OkHttp, handling errors, retries, and offline scenarios gracefully. - Manage local data persistence using Room, SQLite, or SharedPreferences depending on the complexity of the data model. - Handle push notifications, analytics, and crash reporting via Firebase services including FCM, Analytics, and Crashlytics. - Write unit and instrumented tests using JUnit, Espresso, and Mockito to ensure reliable app behaviour across devices. - Profile and optimise app performance with a focus on battery usage, memory consumption, and smooth UI rendering. Qualifications - 3+ years of native Android development in Java with published apps or significant professional project experience. - Strong knowledge of the Android SDK, Android Studio IDE, and Gradle build system configuration. - Hands-on experience with Jetpack libraries including ViewModel, LiveData, Navigation, and WorkManager. - Proficiency integrating REST APIs using Retrofit and OkHttp with proper error handling and response parsing. - Experience with local data persistence using Room or SQLite, including migrations and complex queries. - Working knowledge of Firebase services for notifications, analytics, remote config, and crash reporting. - Fluency in English and Russian.
