Job Summary
Design and operate the shared agent harness and backend infrastructure powering long-running, high-value workflows across OpenAI and third-party products. Build reusable capabilities spanning search, connected context, computer use, memory, tool execution, delegation, and multi-agent orchestration. Establish secure execution environments, identity management, observability, and evaluation frameworks to ensure safe, reliable, and efficient production operations. Partner with Research, Codex, and applied product teams to translate model progress into measurable gains in task completion and latency. This backend-focused role requires strong systems design judgment to abstract complex systems into durable primitives for the next generation of AI agents.

- Proficiency in one or more backend languages such as Python, Go, Rust, TypeScript, or similar, with the ability to move comfortably across service, platform, and product boundaries
- Strong systems design and operational judgment across distributed systems, APIs, workflow orchestration, search or storage, compute and execution, identity and permissions, or observability and reliability
- Infrastructure depth paired with product judgment: you can abstract complex systems into simple, durable primitives that other engineers and developers can build on
- Strong developer empathy and communication skills, including experience partnering with users, research teams, and product engineers to make fast-moving capabilities useful and dependable
- High agency and comfort operating in a fast-moving environment, with strong ownership of security, reliability, and operational excellence
