The role

OpenAI is hiring a Principal Security Engineer for its Infrastructure Security team, which protects GPU clusters, multi-cloud environments, datacenters and the systems holding model weights and user data. The role sets technical direction for security programs across the company.

What you will do

  • Own security outcomes for one or more critical infrastructure areas, including multi-quarter strategy, roadmap and delivery.
  • Design and build security controls across hardware, firmware, OS, Kubernetes, networks and CI/CD against sophisticated and insider threats.
  • Lead cross-functional programs that roll out control changes across large-scale infrastructure without hurting reliability or velocity.
  • Lead threat modeling and design reviews for major infrastructure changes.
  • Mentor engineers on the InfraSec team and partner teams through guidance and reviews.

What they ask for

  • Deep understanding of security principles, common vulnerabilities and sound judgment under ambiguity.
  • Track record of leading large cross-org initiatives from concept to rollout with measurable risk reduction.
  • Deep expertise securing cloud platforms such as AWS and Azure, including multi-cloud networks and cloud-agnostic design.
  • Experience securing on-prem deployments and datacenters, from construction to multi-tenant use.
  • Familiarity with container and orchestration security and authentication/authorization.
  • Skill at automating security work with tooling, and curiosity about using frontier models and agents for security.
  • Clear communication with executive, technical and non-technical audiences.
