Linux Developer

Hiring: Linux System Software Performance Engineer | 8–10 Years Experience

We are looking for an experienced Linux System Software Performance Engineer with strong expertise in Linux performance measurement, kernel tracing, real-time latency analysis, and system-level performance optimization across bare-metal and virtualized environments.

Experience: 8–10 years

Key Responsibilities

• Own end-to-end performance measurement across Linux system software stacks.
• Collect traces, triage performance issues, and perform root-cause analysis.
• Identify and quantify system bottlenecks impacting performance KPIs.
• Analyze hard real-time latency, interrupt latency, scheduler latency, wake-up latency, jitter, and determinism.
• Correlate real-time performance violations with Linux kernel and device-driver paths.
• Measure and analyze performance differences between hypervisor/virtualized and bare-metal environments.
• Perform subsystem-level performance analysis across:
• CPU and vCPU scheduling
• GPU
• NPU
• Memory bandwidth and latency
• Storage/I/O
• Network
• Identify virtualization overhead and provide optimization recommendations.
• Generate trace-backed evidence for performance regressions and sign-off.

Required Skills

• Strong Linux system programming experience.
• Hands-on programming expertise in C, C++, or Python.
• Strong Linux device-driver development experience.
• Hands-on experience with performance/profiling tools such as perf, ftrace, and trace-cmd.
• Experience with scheduler, IRQ, I/O tracing, performance baselining, and regression analysis.

Good to Have

• Real-time Linux performance experience.
• Hypervisor/virtualization performance exposure.
• Kernel, driver, or middleware performance optimization experience.
• Power and Performance (PnP) exposure.

If your experience aligns with Linux kernel/system performance, real-time latency analysis, tracing, and virtualization performance, please apply or reach out to discuss the opportunity.
