4.0 - 10.0 years

4 - 8 Lacs

Bengaluru, Karnataka, India

On-site

Key Responsibilities: Design, develop, and maintain Linux kernel power management features (suspend/resume, CPU idle, DVFS, runtime PM). Work closely with hardware and platform teams to enable low-power modes for embedded SoCs. Analyze and debug power-related kernel issues , system hangs, or wakeup failures. Modify or extend kernel subsystems (e.g., PM framework, cpuidle, cpufreq, thermal). Tune Device Tree entries and drivers to ensure correct power domain usage and clock gating. Use tools like ftrace, powertop, kernelshark, perf , and pm-qa to monitor power behavior and system activity. Contribute to kernel board support packages (BSPs) for new platforms. Ensure system stability and compliance with upstream or vendor kernel baselines. Required Skills & Experience: Strong experience with Linux Kernel internals , particularly in Power Management . Hands-on experience with C programming for kernel-space. Familiarity with Device Tree , platform drivers, clocks, and regulators. Good understanding of low-power states , SoC power rails, and clock domains. Proficient in debugging tools and techniques for kernel issues (e.g., ftrace, crash, serial logs). Experience working on ARM-based architectures (e.g., Cortex-A series). Exposure to git , kernel build systems (Make, Kconfig), and cross-compilation toolchains.
