AI Agent Core Infrastructure Engineer

OpenAI is seeking engineers to build the infrastructure that powers Codex agents in production. You’ll design and operate sandboxed execution environments, orchestration, stateful workflows, app-server and SDK boundaries, and model rollouts.

You’ll work at the intersection of distributed systems, developer tooling, and AI, building primitives that make Codex faster, safer, more reliable, and easier for the rest of the organization to build on.
