Senior Software Engineer, Infrastructure, High Performance Networking

Google•New York, NY

About The Position

Google's software engineers develop the next-generation technologies that change how billions of users connect, explore, and interact with information and one another. Our products need to handle information at massive scale, and extend well beyond web search. We're looking for engineers who bring fresh ideas from all areas, including information retrieval, distributed computing, large-scale system design, networking and data storage, security, artificial intelligence, natural language processing, UI design and mobile; the list goes on and is growing every day. As a software engineer, you will work on a specific project critical to Google’s needs with opportunities to switch teams and projects as you and our fast-paced business grow and evolve. We need our engineers to be versatile, display leadership qualities and be enthusiastic to take on new problems across the full-stack as we continue to push technology forward. 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 NIC. 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. Behind everything our users see online is the architecture built by the Technical Infrastructure team to keep it running. From developing and maintaining our data centers to building the next generation of Google platforms, we make Google's product portfolio possible. We're proud to be our engineers' engineers and love voiding warranties by taking things apart so we can rebuild them. We keep our networks up and running, ensuring our users have the best and fastest experience possible.
