HMI Android App Developer

We are looking for an SDE  to join our Vehicle Software team and independently deliver Android-based HMI features for automotive and electric vehicle platforms. You will own features from design through integration and release, strengthen application reliability, and work across vehicle, platform and connected-service interfaces.

• Design, develop and maintain production Android HMI applications using Kotlin and Jetpack Compose.

• Own complete features across dashboards, charging, vehicle controls, notifications and connected experiences.

• Design reusable UI components, ViewModels and repositories with clear boundaries and testable interfaces.

• Integrate CAN signals and vehicle commands through platform APIs, including acknowledgements and error handling.

• Manage concurrent vehicle, network and user events using Coroutines, Flow and lifecycle-aware state management.

• Implement reliable transitions across key-on/off, riding, charging, OTA and shutdown states, including warning priorities.

• Integrate APIs and relevant Bluetooth, navigation or OTA modules; handle service interruptions and recovery.

• Investigate crashes, ANRs, memory leaks and rendering issues; improve startup time and responsiveness on HMI hardware.

• Write automated tests, review code, guide junior engineers and support build and release readiness.

• Work with design, platform, firmware, mobile, backend and QA teams to resolve integration and field issues.

• 1–6 years of professional Android application development experience, with independent feature ownership.

• Bachelor’s or Master’s degree in Computer Science, Information Technology, Electronics or a related engineering discipline.

• Strong proficiency in Kotlin, Jetpack Compose and modern Android development practices.

• Strong knowledge of Android SDK, lifecycle, permissions, receivers and interaction with system services.

• Hands-on experience with MVVM or MVI, repository patterns and dependency injection using Koin or equivalent tools.

• Strong understanding of Coroutines, Flow, StateFlow, SharedFlow, cancellation, thread safety and resource cleanup.

• Experience with REST APIs, JSON, local persistence, network failure handling and data synchronization.

• Familiarity with CAN communication and vehicle signals, plus practical experience with automotive or connected-device interfaces.

• Hands-on debugging with Android Studio, ADB, Logcat and profiling tools; strong analytical and problem-solving skills.

• Experience writing unit/UI tests, reviewing code and following Git-based development workflows.

• Working knowledge of Gradle, build flavors, signing, R8/ProGuard and production quality requirements.

• Depth in BLE GATT, bonding and reconnection, including Android/iOS notification and media integration.

• Experience with Mappls or other navigation SDKs, GPS/GNSS and map lifecycle management.

• Exposure to privileged Android apps, custom system services, Binder/AIDL or AOSP integration.

• Experience with OTA preconditions and update-agent coordination, or vehicle variant configuration.

• Familiarity with Macrobenchmark, LeakCanary, Crashlytics, CI/CD, secure storage or multimedia optimization.

• Strong problem-solving and analytical ability.

• Good understanding of Android fundamentals beyond UI development.

• Ability to take ownership of assigned features and deliver them with appropriate engineering guidance.

• Ability to understand requirements and translate them into maintainable technical solutions.

• Willingness to participate actively in design discussions and code reviews.

• Ability to collaborate effectively with product, design, backend, QA, and other engineering teams.

• Curiosity to learn new technologies, platforms, and domain concepts.

• Focus on writing clean, maintainable, testable, and scalable code.
