Linux and Android Device Driver - Development

Linux - Android Device Driver

Works in the area of Software Engineering, which encompasses the development, maintenance and optimization of software solutions/applications.
1. Applies scientific methods to analyse and solve software engineering problems. 2. He/she is responsible for the development and application of software engineering practice and knowledge, in research, design, development and maintenance. 3. His/her work requires the exercise of original thought and judgement and the ability to supervise the technical and administrative work of other software engineers. 4. The software engineer builds skills and expertise of his/her software engineering discipline to reach standard software engineer skills expectations for the applicable role, as defined in Professional Communities. 5. The software engineer collaborates and acts as team player with other software engineers and stakeholders.

Essential Skills

• Linux Kernel & Driver Development : Strong experience with Linux kernel internals and writing device drivers.
• Android Internals : Understanding of Android architecture, especially HAL, AIDL, and system services.

Key Responsibilities

• Driver Development : Write and maintain device drivers for hardware components like sensors, cameras, touchscreens, and communication interfaces (e.g., I2C, SPI, UART).
• Kernel Integration : Modify and configure the Linux kernel to support new hardware features.
• Android HAL (Hardware Abstraction Layer) : Develop and integrate HAL modules to bridge drivers with Android services.
• System Debugging : Use tools like adb, logcat, and kernel logs to troubleshoot hardware-software issues.
• Performance Optimization : Ensure drivers are efficient, stable, and power-conscious.
• Collaboration : Work closely with hardware teams, Android framework developers, and QA engineers.
