Security Infrastructure Engineer

This role designs, builds, and operates identity and access management systems that scale across cloud infrastructure, SaaS platforms, and internal services at AI companies. Engineers here balance automation with compliance, implementing SSO consolidation, RBAC models, and lifecycle management while reducing access sprawl and supporting rapid business growth. They work at the intersection of security governance and operational efficiency, partnering with infrastructure, IT, and compliance teams to embed least-privilege access into AI development workflows and multi-cloud environments. The role sits within security or infrastructure teams and demands expertise in identity platforms like Okta, cloud IAM services, and scripting automation to protect critical assets while enabling researchers and engineers to move quickly.
