Security Engineer, AI Infrastructure
Brain Co., San Francisco Bay Area +3
The role
As our Security Engineer, Infrastructure, you'll secure the platform layer end-to-end including cloud infrastructure, Kubernetes, identity, networking, and the systems that AI runs on. This is a hands-on builder role. You'll write code, ship infrastructure, and work shoulder-to-shoulder with our infra team as a true engineering partner, not a reviewer. It's a high-ownership role for someone who wants to build secure-by-default infrastructure from first principles, and grow the function as the company scales.
