Hyderabad, Telangana, India

On-site

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. Required Qualifications: Bachelor's or Master's degree in Computer Science, Electrical Engineering, or a related field. 5+ years of experience in Linux performance analysis and tuning on embedded or consumer platforms. Deep knowledge of Linux internals: process scheduling, memory management, NUMA, file systems, block devices, I/O stack, etc. Strong proficiency with performance tools: perf, top, htop, vmstat, iotop, powertop, ftrace, strace, systemtap, LTTng, eBPF, systemd-analyze, bootchart, blktrace, oprofile
