Linux Performance Developer - Linux Kernel

Key Responsibilities :

• Analyze, measure, and optimize system performance across the full Linux stack-kernel, drivers, user-space services, and applications.
• Profile CPU, memory, I / O, GPU, and power usage to identify performance bottlenecks and inefficiencies.
• Develop and deploy performance monitoring and tracing tools (e.g., perf, ftrace, eBPF, systemtap, trace-cmd, BPFtrace).
• Work closely with kernel, power, graphics, boot, and user-space teams to tune and enhance system responsiveness and throughput.
• Optimize boot time, application launch latency, and system suspend / resume cycles for better end-user experience.
• Tune scheduler, interrupt handling, memory management, and I / O subsystems for target hardware platforms.
• Validate performance under various workloads (interactive, background, thermal stress) and ensure consistent behavior.
• Collaborate with hardware and firmware teams to align software performance with platform power and thermal constraints.
• Automate performance regression testing and define KPIs to track across software releases.
• Investigate and resolve thermal throttling, CPU / GPU frequency scaling, and battery drain issues in coordination with power and thermal teams.
