Responsibilities
Performance Analysis and Optimization
  • Identify and analyze performance bottlenecks across CPU, memory hierarchy, cache, interconnect, and interrupt subsystems.
  • Leverage hardware PMU counters to measure and interpret cycles, instructions, cache misses, branch mispredictions, TLB misses, and stall cycles.
  • Compute and analyze performance metrics such as IPC, CPI, MPKI, memory bandwidth utilization, and stall breakdowns.
  • Optimize system software, applications, and drivers for throughput, latency, and performance determinism.

Virtualization Performance Tuning
  • Profile and reduce hypervisor overhead, including VM exits, interrupt injection, and stage-2 MMU translation costs.
  • Optimize vCPU placement strategies, huge page usage, and IRQ affinity for performance-sensitive workloads.
  • Analyze and tune virtio and IOMMU performance paths.
  • Investigate cross-core and cross-cluster latency issues, including IPI overhead and interrupt routing on ARM-based systems.

CPU PMU and Microarchitectural Analysis
  • Configure and interpret ARM PMUv3 and related vendor-specific performance monitoring extensions.
  • Apply Top-Down Microarchitecture Analysis (TMA) to identify frontend/backend bottlenecks.
  • Correlate PMU-derived metrics with kernel traces, source code paths, and system behavior.
  • Design and implement custom event sets tailored to workload-specific performance characterization.

Required Qualifications
  • Bachelor's, Master's, or Ph.D. in Computer Science, Electrical Engineering, or a related field.
