About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the Role Anthropic's U.S. Industrial Security team owns the company’s Facility Security Clearances (FCL), Personnel Security (PERSEC), Contracts and DD254s, Policies/Procedures/Automation/Metrics, and Compliance across the Defense Industrial Base and U.S. Intelligence Community.
