About the Team

Security is at the foundation of OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity.

Our Security team tenets include: prioritizing for impact, enabling researchers, preparing for future transformative technologies, and engaging a robust security culture.

About the Role

As a Security Engineer you will join our OpenAI engineers and researchers in building, operating and securing transformational AI technologies.

  • Develop, measure, and tune detection rules to ensure effective and sustainable operations.

  • Automate manual response processes

  • Ensure visibility and control of OpenAI’s endpoint fleet (macOS, Windows)

  • Driving improvements across identity access and management (IAM), device management, productivity software, and our use of public cloud environments (e.g. AWS, Microsoft Azure)

You might thrive in this role if you:

  • Experience in Security or a Security-adjacent field

  • Experience with Microsoft Azure and/or cloud infrastructure platforms

  • Knowledge of modern adversary tactics, techniques, and procedures.
