Security Engineer, Infrastructure Security

OpenAI OpenAI · AI Frontier · United States · Remote · Security

Security Engineer focused on protecting the infrastructure that supports AI models, including GPU clusters, cloud environments, and data storage. The role involves designing and building security controls, collaborating with engineering teams, and addressing high-impact security projects for AI workloads.

What you'd actually do

  1. Design and build security controls across diverse layers (e.g., physical hardware, firmware/BMC, OS, Kubernetes, networks, and CI/CD) to defend against sophisticated adversaries and insider threats.
  2. Collaborate with engineering and security teams to drive deployment of security enhancements and control changes across broad-scale infrastructure.
  3. Tackle high-impact projects such as checkpoint encryption, network isolation, secret management, and machine identity, while continuously raising the security bar for emerging AI workloads.
  4. Take a generalist approach to building security controls, balancing a mix of security expertise and broad technical skillsets to adapt to evolving challenges.

Skills

Required
