Data Center Security Engineer

About the Role

As part of a small team of data center security experts, the successful candidate will drive security architecture, control validation, and defensive improvements across multiple, diverse environments. The focus will be on IT, Enterprise, ICS, and Operational Technology (OT) networking, with an emphasis on securing OT and IT networking environments through strong segmentation, access control, monitoring, hardening, and connectivity patterns suited to critical infrastructure.

What You Will Do

• Design and implement security controls that protect data center infrastructure across a growing global footprint, with particular focus on both OT and IT networking environments.
• Partner closely with a small team of data center security specialists, as well as engineering, operations, and broader security teams, to deliver resilient and practical security outcomes.
• Secure OT and IT networking environments through strong segmentation, access control, monitoring, hardening, and connectivity patterns suited to critical infrastructure.
• Contribute to security architecture and design reviews for data center systems, including OT and IT networking, network segmentation, identity and access management, provisioning workflows, hardware and firmware trust boundaries, and operational safeguards.
• Perform recurring audits, control assessments, and validation activities across OT and IT networking environments to ensure continued compliance against defined controls.
• Drive ongoing evidence collection, gap tracking, and remediation follow-through so control deficiencies are identified quickly and closed durably.
• Help define measurable security standards, control objectives, audit procedures, evidence requirements, and validation mechanisms for infrastructure and facility security programs.
• Support security monitoring, incident response, and post-incident improvement efforts for data center, OT, and IT networking environments.
• Work with suppliers, partners, and internal stakeholders to evaluate and reduce risks associated with third-party hardware, firmware, software, and operational dependencies.
• Continually evolve the security of our data centers alongside changes in adversary activity, infrastructure complexity, and the increasing demands of Openai's systems.

What We Are Looking For

• 15+ years of experience in security, including meaningful hands-on experience securing large-scale infrastructure, industrial environments, or data center systems.
• Deep expertise securing OT and IT networking environments in critical infrastructure settings, including segmentation strategies, remote access controls, and threat detection.
• Experience with security architecture and design reviews for data center systems, including OT and IT networking, network segmentation, and identity and access management.
• Strong understanding of security controls, including access control, monitoring, hardening, and connectivity patterns suited to critical infrastructure.
• Experience performing recurring audits, control assessments, and validation activities across OT and IT networking environments.
• Ability to drive ongoing evidence collection, gap tracking, and remediation follow-through.
• Experience defining measurable security standards, control objectives, audit procedures, evidence requirements, and validation mechanisms.
• Strong understanding of security monitoring, incident response, and post-incident improvement efforts.

Nice to Have

• Experience with security information and event management (SIEM) systems and incident response platforms.
• Knowledge of cloud security and compliance frameworks, such as AWS or Azure.
• Familiarity with containerization and orchestration technologies, such as Docker and Kubernetes.
• Experience with automation tools, such as Ansible or SaltStack.

• Competitive salary and benefits package.
• Opportunity to work with a cutting-edge AI company.
• Collaborative and dynamic work environment.
• Professional development opportunities.
• Flexible working hours and remote work options.
• Access to the latest security technologies and tools.
• Comprehensive health insurance and wellness programs.
• Generous paid time off and vacation policy.

• Develop a strong portfolio showcasing your experience in securing large-scale infrastructure and industrial environments.
• Stay up-to-date with the latest security challenges and technologies, including cloud security and compliance frameworks.
• Be prepared to discuss your approach to security architecture and design reviews, as well as your experience with security controls and threat detection.
• Highlight your ability to work collaboratively with cross-functional teams, including engineering, operations, and security teams.
• Consider obtaining certifications in security or related fields to demonstrate your expertise and commitment to the field.
• Prepare to discuss your experience with security information and event management (SIEM) systems and incident response platforms.
• Research the company culture and values to understand how your skills and experience align with Openai's mission and goals.
