OpenAI's Hardware organization is hiring a performance modeling engineer to build and maintain tools that model AI system behavior. The work covers simulations and analytical models of compute, memory, interconnect and storage, distributed scaling bottlenecks, and validating models against real measurements, feeding into architectural and vendor decisions. The posting asks for a strong software or modeling background, familiarity with system architecture fundamentals, and comfort with quantitative analysis; exposure to AI/ML workloads is preferred. Hybrid, three days a week in San Francisco, with relocation assistance.
