Software Engineer, API Multicloud

We’re looking for experienced infrastructure engineers to design, build, and operate the systems that run OpenAI’s API across CSP platforms. You’ll help establish the cloud deployment platform: configuring and launching model-serving environments, planning capacity, improving caching and utilization, and making new releases safe and repeatable. Working closely with inference engineers, you’ll connect advances in model serving to the infrastructure and operational practices needed to run them reliably in production.

The role calls for strong distributed systems judgment and comfort moving across API services, cloud infrastructure, deployment tooling, and production debugging. You’ll work directly with CSP engineers to navigate differences in infrastructure, native services, and operating models, resolve integration issues, and build reusable solutions that reduce repeated work as we expand. Your decisions will affect how quickly new capabilities reach customers, how reliably they run, and how efficiently we use cloud resources.
