OpenAI's Hardware organization is hiring a software engineer to build the low-level device runtime for its custom AI accelerator. The work covers kernel-launch scheduling, command submission and queueing, device memory and address spaces, synchronization primitives, and interfaces to drivers, firmware, compilers and kernels. The posting asks for strong low-level systems programming in C, C++, or Rust, plus familiarity with concurrency, memory ordering, DMA and coherency. Cycle-accurate simulation experience is used to develop and tune runtime behavior before silicon exists. San Francisco, hybrid.
