[Remote] Data Center Security Technical Lead at OpenAI

The Data Center Security Technical Lead will spearhead the overall security vision, architecture, execution, and sustained operations to protect data center infrastructure globally. This role involves recruiting, mentoring, and leading a diverse, distributed team of security professionals across multiple time zones. Responsibilities include integrating hardware-rooted trust, segmented enclaves, side-channel mitigations, and insider-risk countermeasures. The lead will drive security design reviews, threat modeling, supply-chain risk assessments, secure provisioning, runtime monitoring, incident response, and structured decommissioning. Collaboration with engineering, operations, and security teams to define and enforce security best practices, including network segmentation, physical security, identity management, and access control, is crucial. Engaging with suppliers and partners to mitigate third-party risks, preparing executive-level updates on risk posture and compliance, and ensuring facilities meet strict compliance requirements are also key duties. The role requires continually evolving data center security in response to cybersecurity advancements, adversary activity, and the increasing sophistication of frontier models.
