Software Engineer, Cloud Agents

Backend and infrastructure work on the platform that runs OpenAI's agentic workloads, building the orchestration, sandboxing and storage systems behind Codex, ChatGPT and the OpenAI API. The posting frames it as platform work in service of product teams rather than product work itself: the job is to define the right abstractions and let product engineers ship on them quickly. It asks for strong backend or infrastructure depth, and is explicit that the systems in question run untrusted agent code at scale, which is what makes the sandboxing a first-class concern rather than a detail.
