OpenAI's Codex Core Agents team is hiring an AI systems engineer to build the harness that turns model outputs into actions: tool use, code execution, sandboxing, orchestration, and state and workflow infrastructure. The work spans evals and ablations across prompts, context and tool-use strategies, plus observability, profiling and inference/runtime performance across GPUs and fleet capacity. The posting asks for production distributed-systems experience, Rust and Python, and hands-on work with LLM applications, coding agents, evals or inference. The harness is open source, and the role sits close to research.
