Senior Performance Engineer

NWe are seeking a highly skilled Senior Performance Engineer to join our Performance and R&D organizations. In this role, you will help build and evolve systems that support performance analysis, telemetry, and optimization for large-scale GPU- and CPU-based clusters used in AI and high-performance computing environments. You will work closely with hardware, networking, firmware, and software teams to collect, analyze, and interpret performance data from live systems. This is a fast-paced R&D environment where system behavior and requirements evolve rapidly, requiring adaptable engineering solutions and strong analytical thinking.What youll be doing:Profile, benchmark, and analyze AI and HPC workloads on GPU and CPU clustersExplore performance characteristics of high-performance networking and collective communications (e.g., NCCL, RDMA, MPI, RoCE)Identify performance bottlenecks across networking, compute, memory, and system architectureDevelop and enhance performance analysis,דרישות:B.Sc. or M.Sc. in Computer Science, Computer Engineering, Software Engineering, or equivalent experience5+ years of experience in performance analysis, systems engineering, or HPC/AI infrastructureDemonstrated expertise in performance analysis skills and methodologiesHands-on experience with high-performance networking (RDMA, MPI, NCCL, congestion control)Strong understanding of system performance metrics (latency, throughput, resource utilization)Exposure to hardware, firmware, or embedded telemetry environmentsStrong analytical, problem-solving, and communication skillsAbility to work effectively in cross-functional, fast-paced R&D teamsWays to stand out from the crowd:Knowledge of CUDA, NCCL internals, and congestion control algorithmsDeep system-level understanding of CPU architectures, GPUs, HCAs, memory, and PCIeExperience with our GPUs, CUDA, and deep learning frameworks such as PyTorch or TensorFlowExperience with cloud platforms Proficiency in Python; experience
