Security Engineer, Infrastructure Security
OpenAIRole Description & Requirements
About the Team
Security is at the foundation of OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity.
The Security team protects OpenAI’s technology, people, and products. We are technical in what we build but are operational in how we do our work, and are committed to supporting all products and research at OpenAI. Our Security team tenets include: prioritizing for impact, enabling researchers, preparing for future transformative technologies, and engaging a robust security culture.
About the Role
OpenAI is seeking a Security Engineer to join our Infrastructure Security (InfraSec) team. InfraSec protects the foundations of OpenAI’s research and production environments, spanning GPU supercomputing clusters, multi-cloud infrastructure, datacenters, networking, storage, and the critical services that power our frontier AI models. Our charter includes securing everything from bare-metal hardware and firmware, to Kubernetes clusters and service meshes, to data storage and access pathways for highly sensitive model weights and user data.
In this role, you will:
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.
Collaborate with engineering and security teams to drive deployment of security enhancements and control changes across broad-scale infrastructure.
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.
Take a generalist approach to building security controls, balancing a mix of security expertise and broad technical skillsets to adapt to evolving challenges.
You will thrive in this role if you have:
Deep understanding of security principles, best practices, and common vulnerabilities.
A proactive mindset, with the ability to identify and address security gaps or inefficiencies through automation and tooling.
A track record of delivering scalable solutions and driving impactful changes 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.
Excitement about collaborating with cross-functional teams to build secure, reliable systems that scale globally.
