Enterprise Security protects the systems, identities, devices, and services that enable OpenAI's employees to work securely and effectively. We partner across IT and Security to understand risk, build practical defenses, and support a rapidly evolving technical environment. We are looking for an Enterprise Security Engineer with a focus on vulnerability management, novel vulnerabilities, and zero-day response. You will investigate vulnerabilities and security weaknesses across networks, endpoints, and SaaS, prioritize them in the context of real exposure, and drive remediation through verified outcomes. You will also build security capabilities and automation, use AI agents to solve practical problems, and help shape how enterprise security operates as agents become a larger part of everyday work. This role is open to candidates in San Francisco, CA, and to remote candidates in the United States.
