About the Role We’re building the future of programmatic advertising through AI agents. Our Agentic Marketplace team is creating the infrastructure that enables AI agents to discover, negotiate, and transact media inventory autonomously. In this role, you’ll be a technical leader responsible for the APIs, protocols, and agent interfaces that power our agentic advertising platform.
