Senior System Performance Engineer

Accountabilities:: Define and execute comprehensive performance validation strategies for Ethernet hardware and software subsystems across different platforms and workloads. Characterize system performance using metrics such as throughput, packets per second, latency, jitter, buffer utilization, CPU efficiency, and memory efficiency. Analyze end-to-end packet processing pipelines to identify performance bottlenecks across hardware components, drivers, firmware, and software stacks. Develop and apply methodologies to optimize Ethernet datapath performance across varying traffic patterns, workloads, and system configurations. Evaluate the performance of Ethernet MAC, PHY, switch, NIC, and packet-processing hardware to identify opportunities for optimization. Analyze bus utilization, DMA performance, memory bandwidth, cache efficiency, and hardware acceleration mechanisms to understand their impact on overall system performance. Perform performance characterization across both pre-silicon and post-silicon platforms, helping identify issues early and validate system behavior on production hardware. Collaborate cross-functionally with system architects, hardware engineers, firmware developers, driver teams, and performance architects to diagnose issues and implement optimization strategies. Conduct detailed root-cause analysis and translate performance findings into actionable engineering recommendations and improvements.
