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 prospect.
