OpenAI's Core Network Engineering team is hiring a full-time software engineer in San Francisco, on-site, to build and run the networking that connects its training and inference compute. Work covers host networking, data-center fabrics and wide-area links: provisioning automation, observability tooling, protocol validation, and performance tuning. The posting asks for experience operating large-scale network or distributed systems, comfort near the hardware-software boundary, familiarity with Linux networking, NICs, RDMA, InfiniBand, RoCE or DPDK, and production code in C++, Python or Go.
