About the Team
Join the security team at OpenAI, where we're building the future of AI while ensuring it benefits all of humanity. We're a team of technical experts dedicated to protecting OpenAI's technology, people, and products. We prioritize impact, enable researchers, prepare for future transformative technologies, and cultivate a robust security culture. We believe security is at the very foundation of our mission.
About the Role
We're seeking a talented Security Engineer to join our Infrastructure Security (InfraSec) team. As part of InfraSec, you'll be defending the very foundations of OpenAI's research and production environments, including our massive GPU supercomputing clusters, multi-cloud infrastructure, datacenters, networking, and storage systems. You'll play a critical role in securing the services that power our groundbreaking AI models. Our mission covers everything from bare-metal hardware and firmware to Kubernetes clusters, service meshes, data storage, and access pathways for highly sensitive model weights and user data. This is a chance to have a real impact on the security of cutting-edge AI research.
What You'll Do
Design and build robust security controls across diverse layers (physical hardware, firmware/BMC, OS, Kubernetes, networks, CI/CD) to defend against sophisticated adversaries and insider threats.
Collaborate closely with engineering and security teams to drive the deployment of critical security enhancements and control changes across our expansive infrastructure.
Tackle high-impact projects, such as checkpoint encryption, network isolation, secret management, and machine identity, continuously raising the security bar for emerging AI workloads.
Take a generalist approach to building security controls, blending security expertise with broad technical skills to adapt to evolving challenges and stay ahead of the curve.
What You'll Bring
Deep understanding of security principles, best practices, and common vulnerabilities.
A proactive, threat-hunting mindset, with the ability to identify and address security gaps or inefficiencies through automation and tooling.
A proven track record of delivering scalable solutions and driving impactful security improvements across infrastructure in real-world projects.
Expertise in the security of cloud platforms (e.g., Amazon AWS, Microsoft Azure), especially securing multi-cloud networks and infrastructure, and designing cloud-agnostic systems.
Experience securing on-prem deployments and datacenters from construction to multi-tenant use.
Familiarity with container security, orchestration security, and authentication/authorization.
Strong analytical and problem-solving skills, with an ability to think critically and objectively assess security risks.
Excellent communication skills, with the ability to convey complex security concepts to technical and non-technical stakeholders.
A passion for collaborating with cross-functional teams to build secure, reliable systems that scale globally.
