Senior Android Developer

Role: HMI Senior Developer Android Automotive (AAOS)

Location: Chennai

Experience: 4 - 7 years

Core Responsibilities:

• HMI Application Development: Design and develop production-grade Android HMI applications for vehicle cluster and infotainment screens using Jetpack Compose, following MVVM and clean architecture principles.

• Connectivity Features: Build and maintain Bluetooth (Classic & BLE) and Wi-Fi features pairing, GATT communication, HFP/A2DP/PBAP profiles, network scanning, connection management, and failure/error-state handling.

• AIDL & IPC: Design and implement AIDL interfaces for inter-process communication between system apps, services, and privileged components; work with Binder IPC and bound/overlay services.

• Concurrency & Real-Time Behavior: Apply asynchronous programming (Kotlin Coroutines, Flow/StateFlow), multi-threading, and multi-tasking patterns to deliver responsive, real-time vehicle HMI experiences under strict latency constraints.

• Vehicle Bus Integration: Work with CAN / CAN FD data to surface real-time vehicle signals (speed, battery, telemetry, diagnostics) in the HMI layer, coordinating with the vehicle networking/embedded team.

• System Integration: Integrate with privileged/system-level APIs, Vehicle HAL, and platform-signed components specific to AAOS.

• Performance & Reliability: Diagnose and resolve UI performance issues, memory leaks, ANRs, recomposition inefficiencies, and state-management bugs.

• Code Quality & Security: Conduct code reviews with attention to secure handling of credentials and sensitive data, and enforce clean, testable architecture across feature modules

• Cross-Functional Collaboration: Partner with platform/framework, embedded, QA, and UX teams to ship features across the full HMI stack from UI to Binder to hardware.

• Required Technical Skills: Languages: Strong proficiency in Kotlin and Java, working knowledge of C/C++ and JNI is a plus. Android/AAOS: Jetpack Compose, Hilt / Dagger dependency injection, Navigation, Android Automotive OS (AAOS) app development, system/privileged app permissions. Connectivity: Bluetooth Classic & BLE (GATT, profiles), Wi-Fi APIs (WifiManager, WifiConfiguration/network suggestion APIs), TetheringManager/hotspot.

• IPC: AIDL, Binder IPC, bound services, cross-process ViewModel/EntryPoint access patterns. Concurrency: Kotlin Coroutines, Flow/StateFlow/SharedFlow, structured concurrency, multi-threading, and real-time/embedded systems concepts (mutex, semaphores, synchronization).

• Vehicle Networking: Good working knowledge of CAN / CAN FD protocols and reading vehicle bus signals into an application layer. Tools: Android Studio, Git/Gerrit, Gradle, AOSP build basics; familiarity with adb, systrace/Perfetto for profiling. Good to Have: Exposure to Android Automotive VHAL/Car API, EV domain knowledge (BMS, telemetry, range estimation), unit/UI testing (JUnit, Espresso, Compose testing), CI/CD for Android.

• Education: A Bachelor's or Master's degree in Computer Science or a related engineering field.
