AI SummaryOpenAI is hiring a Principal Security Engineer to set strategy and deliver high-impact infrastructure security controls across research and production environments. The role covers security from hardware, firmware, and datacenters through cloud platforms, Kubernetes, networks, storage, and CI/CD. This principal-level engineer will lead cross-functional security programs, conduct threat modeling and design reviews, and balance robust controls with reliability and engineering velocity. Success requires deep cloud and on-premises security expertise, strong judgment under ambiguity, and the ability to mentor engineers and communicate with varied stakeholders. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 5/5EasyHard ### Pace & Pressure 5/5RelaxedFast-paced ### Autonomy Level 5/5GuidedFull ownership ### Communication Load 5/5IndependentCollaborative AI insightThis is a principal-level role securing highly sensitive, globally scaled AI infrastructure across many technical layers and organizational boundaries.

I would define a prioritized roadmap around strong identity controls, segmentation, secure hardware and workload baselines, centralized telemetry, and tested incident response, then establish measurable risk-reduction outcomes and rollout milestones with infrastructure partners. Describe how you would balance a security control rollout with platform reliability and developer velocity. I would engage platform owners early, document the security objective and operational constraints, and test the control in a representative environment before broad deployment. I would use phased rollouts, automation, clear exception processes, observability, and rollback plans, measuring both security coverage and reliability impact so the final control is durable rather than merely restrictive. What security risks are particularly important for Kubernetes environments supporting critical workloads? Key risks include excessive RBAC privileges, compromised service accounts, weak admission controls, vulnerable images, insecure secrets handling, insufficient network isolation, and poor audit visibility. I would address these through least-privilege identity design, workload policy enforcement, image provenance and scanning, secrets management, network policies, runtime detection, and comprehensive logging. How would you approach securing on-premises datacenter hardware from construction through multi-tenant operation? I would establish physical-security and supply-chain requirements first, including asset provenance, secure receiving, tamper controls, and lifecycle tracking. Technical controls would include firmware and BMC hardening, secure boot and attestation where available, segmented management networks, tightly controlled break-glass access, continuous inventory, and monitoring for configuration drift and anomalous activity. Tell us about a time you would need to influence senior stakeholders to accept a significant infrastructure security change. I would frame the discussion in terms of concrete attack paths, business impact, operational tradeoffs, and viable implementation options rather than presenting security as an abstract requirement. By proposing a staged plan with ownership, success metrics, reliability safeguards, and a transparent risk-acceptance path for exceptions, I can help stakeholders make an informed decision and build alignment around the preferred solution. 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 Principal 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. As a principal engineer, you will set technical direction and drive execution on high-impact infrastructure security programs, partnering across various orgs at OpenAI to deliver durable controls that raise the security bar at OpenAI scale. In this role, you will: * Own end-to-end security outcomes for one or more critical infrastructure areas, including multi-quarter strategy, roadmap, and delivery. * 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. * Lead cross-functional programs to deploy security enhancements and control changes across broad-scale infrastructure, balancing security guarantees with reliability and velocity. * Take a generalist approach to building security controls, balancing a mix of security expertise and broad technical skillsets to adapt to evolving challenges. * Lead and/or drive threat modeling and design reviews for major infrastructure changes, ensuring strong security foundations and operational excellence. * Mentor and level up engineers across InfraSec and partner teams, contributing to a strong security culture through guidance, reviews, and technical leadership. You will thrive in this role if you have: * Deep understanding of security principles, best practices, and common vulnerabilities, including strong security judgment under ambiguity * A proactive mindset, with the ability to identify and address security gaps or inefficiencies through automation and tooling. * Expertise and curiosity about using frontier models and agents to effectively solve security challenges. * A track record of leading large, cross-org initiatives from concept to rollout, including navigating tradeoffs, driving alignment, and delivering measurable risk reduction. * Deep 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 executive, technical, and non-technical stakeholders. * Excitement about collaborating with cross-functional teams to build secure, reliable systems that scale globally.
