The role involves bringing benchmarks and real-world workloads onto new hardware platforms, measuring performance across compute, memory, storage, and networking, finding bottlenecks, and adapting workloads to use hardware better. It also requires debugging across software, runtime, and hardware boundaries and sharing findings with hardware, modeling, and software teams. The posting asks for performance-analysis or optimization experience, CPU/GPU and I/O knowledge, profiling skills, and distributed-systems experience. AI/ML workload and accelerator experience is preferred. Hybrid, San Francisco-based, with relocation assistance.
