JD for Linux System Programming Performance Engineer
Job Title: Senior System Software Engineer – Performance (Linux)
Experience Required:8–10 years
Location: Bangalore, India
Role Summary
Linux System Software Performance Engineer responsible for performance measurement, trace collection, and triage across bare‑metal and virtualized platforms, with focus on hard real‑time behavior and system‑level performance derates.
Core Responsibilities – PAVS KPIs & Deliverables
- Own end‑to‑end performance measurements across Linux system software stacks
- Collect traces, triage issues, and perform root‑cause analysis for performance deviations
- Identify, quantify, and report system bottlenecks impacting PAVS KPIs
- Generate trace‑backed evidence for performance sign‑off and regressions
- Collect and analyze traces for: hard real‑time latency, Interrupt latency, scheduler latency, wake‑up latency
- Jitter and determinism characterization using kernel traces
- Triage real‑time violations and correlate with kernel / driver paths
Hypervisor vs Bare‑Metal Performance Derates
- Measure and quantify performance derates in virtualized vs bare‑metal environments
- Perform subsystem‑level triage and trace analysis for:
• CPU (scheduling, vCPU overhead)
• GPU (submission latency, virtualization overhead)
• NPU (compute and scheduling impacts, if applicable)
• Memory (bandwidth, latency, contention)
• Disk / Storage (I/O latency, throughput)
• Network (latency, throughput, virtualization overhead)
- Identify virtualization overheads and provide optimization insights
Performance Tooling & Trace Collection
- Kernel and user‑space profiling tools: perf, ftrace, trace‑cmd
- Scheduler, IRQ, I/O trace collection
- Performance baselining and regression tracking
Required Skills
- Strong Linux system programming experience
- Must have strong hands on programming in C, C++, or Python (any one)
- Linux device driver development experience
Good to Have
- Kernel, driver, or middle
