About the role

The High Performance Networking (HPN) team maintains end-to-end (E2E) ownership of the RDMA (Driver + guest) stack. We deliver scalable, high-performance networking solutions to support a wide range of workloads on Google Cloud. Our team is focused on enhancing the performance of HPC and ML workloads utilizing TCP, and enabling and optimizing HPC/ML workloads to leverage the RDMA capabilities of next-generation Smart NICs.

We Perform comprehensive full-stack optimizations to maximize HPC and ML performance across Google Cloud infrastructure. This spans a wide range, from RDMA/Device driver, kernel optimization, userspace communication libraries (e.g., MPI library, libfabric, NCCL, UCX), all the way to customer's HPC and ML applications. Additionally, we develop advanced solutions that leverage Google Cloud's forthcoming RDMA capabilities, specifically those enabled by Diorite and next-generation Smart NICs.
