Android / Linux Kernel Developer

Exp

Candidate should have 3-10 years of experience of working on Android Linux Kernel Upgrades across various chipsets and writing updating performance analysis and optimization of drivers. The role involves working on the Board Support Package (BSP), upgrading kernel and system components, ensuring compatibility with new Android or Linux versions, and integrating vendor-specific changes.

In addition, Candidate would be required to have good working experience of the network drivers, performance measurement, Optimization of Kernel resources used by drivers.

Key Responsibilities:

• Plan, execute, and validate Android And or Linux Kernel upgrades for a multitude of Chipsets having one or more different kernel versions
• Applying Vendor and Device Specific Patches
• Port and maintain Board Support Package (BSP) for SoCs such as Qualcomm
• Update and integrate device drivers for peripherals (e.g., Ethernet, Wi-Fi, Camera, Audio, display, sensors etc).
• Migrate and test any HAL (Hardware Abstraction Layer) changes for Android.
• Perform bootloader updates and ensure secure boot compatibility.
• Debug, resolve issues during the upgrade process (kernel crashes, HAL failures, app compatibility).
• Work closely with QA to ensure stable releases after Kernel and or driver upgrades.
• Document upgrade procedures, patch sets, and integration step.
