Full Time
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.
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
