Software Engineer, Product Infrastructure - Agent Runtime

The posting, as OpenAI wrote it

ABOUT THE TEAM

Agent Runtime builds the shared agent primitives and compute runtime that power OpenAI products and applications. As agents take on more complex, longer-running tasks, we build the systems that let them maintain state, use tools, and work reliably in the environments they need.

We work closely with Research, Product, and infrastructure teams to turn advances in model capabilities into useful products. Our work combines deep systems engineering with a clear understanding of customer needs, creating reusable foundations that help teams build and scale new agent experiences.

ABOUT THE ROLE

We’re looking for a software engineer with strong product infrastructure experience to build the services, APIs, and runtime capabilities behind persistent agents. You’ll focus on the product infrastructure that makes agent workflows reliable and scalable, including persistent state, asynchronous execution, orchestration, and visibility into work in progress.

You’ll bring product judgment to infrastructure decisions: understanding how people and developers use agents, translating those needs into clear abstractions, and owning systems from design through launch and production operation. You’ll work closely with partner teams to deliver new capabilities while strengthening the shared foundations they depend on.

IN THIS ROLE, YOU WILL

• Design, build, and operate backend services, APIs, and reusable runtime primitives that support agent experiences across products.
• Build systems for persistent agent state, asynchronous execution, orchestration, and progress reporting so agents can carry work forward over time.
• Develop infrastructure that connects agents with tools and execution environments, with clear interfaces and safe, reliable behavior.
• Improve reliability, scalability, and performance through observability, production debugging, failure recovery, and thoughtful system design.
• Partner with Product, Research, and engineering teams to turn emerging capabilities and customer needs into reusable infrastructure.
• Own projects end to end, balancing rapid iteration with maintainable architecture and the operational demands of systems used across products.

YOUR BACKGROUND MIGHT LOOK SOMETHING LIKE

• 7+ years of professional software engineering experience, with substantial ownership of backend systems, product infrastructure, or developer platforms.
• A track record of designing, shipping, and operating production services, APIs, and data models that support complex product workflows.
• Strong distributed systems fundamentals and experience reasoning about state, concurrency, asynchronous work, and failure recovery.
• Experience building production systems in Python, Go, Rust, TypeScript, or similar languages, and the ability to work across service and infrastructure boundaries.
• Experience improving reliability and performance, using observability and debugging to understand system behavior and reso
