From the employer's listing (short excerpt)
ABOUT THE TEAM
The Cloud Infrastructure team builds and operates the infrastructure behind OpenAI’s products, including ChatGPT and the API. Within Cloud Infrastructure, the Traffic team owns how traffic enters our cloud environments, moves between services, clusters, and regions, and reaches external dependencies.
Our work spans cloud networking, Kubernetes networking, ingress and egress gateways, proxies, load balancing, and traffic steering. We build the systems, controls, and observability that make these paths reliable, secure, efficient, and straightforward for other engineering teams to use.
ABOUT THE ROLE
You’ll build and operate the networking and traffic infrastructure that connects OpenAI’s products and services across clouds and regions. The team’s work spans L3, L4, and L7—from IP connectivity, NAT, and transport behavior to service proxies and application request routing.
You’ll bring depth in part of this stack and curiosity about how the whole path works. Projects may include building gateways and control planes, improving cross-region connectivity, diagnosing packet loss or connection exhaustion, and making routing changes safer and easier to operate.
