- Extensive practical experience in Linux performance analysis, including knowledge of processes and threads, CPU and memory architecture, NUMA, I/O, and networking.
- Experience investigating performance in multi-node HPC or GPU-accelerated systems, distinguishing local resource bottlenecks from communication overhead, load imbalance, and shared-resource contention.
- Deep expertise in at least one relevant area: GPU application performance, Linux systems performance, high-speed networking and collective communication, parallel storage, or HPC performance tooling.
- Proficiency in Python to build maintainable automation and analysis tools. Experience in developing and debugging performance-sensitive code in C, C++ and CUDA.
- Ability to build controlled experiments, interpret profiling and counter data, and demonstrate reproducible improvements in application performance.
- Independently driving technical efforts across hardware and software boundaries, communicating findings clearly, and working with component owners to resolve issues.
- BS or MS in Computer Science, Engineering, Mathematics, Physics (or equivalent experience), with 8+ years of applicable experience.
Ways to stand out from the crowd
- Experience working with profiling and tracing tools like Nsight Systems, Nsight Compute, Linux perf, or eBPF-based tools.
- Practical experience with RDMA and MPI or NCCL, and analyzing performance across PCIe, NVLink, InfiniBand, or Ethernet interconnects.
- Experience with Slurm, container runtimes, and cgroups, including understanding how workload placement, resource isolation, and CPU/GPU/NIC affinity impact performance.
- Experience improving distributed training, inference, or scientific applications by conducting strong- and weak-scaling studies, or building automated performance regression frameworks using tools such as ReFrame.
