About Brain Co.
Brain Co. is building the infrastructure that turns advanced AI research into real-world impact. We work at the frontier of productionizing AI for complex, high-stakes environments—particularly in government and regulated industries where manual workflows still dominate.
Our mission is to make AI systems reliable, scalable, and dependable in the real world. That means going beyond demos and models to build robust platforms that support complex workflows, human-in-the-loop processes, and production-grade reliability at scale.
What You’ll Work On
Build the security foundations of our AI platform: identity, isolation, and access control.
Embed security into cloud infrastructure, Kubernetes, and deployment workflows.
Create paved roads and guardrails so engineers can move fast safely.
Own auditability, detection, and incident readiness.
You Might Be a Great Fit If You…
Have 3+ years of experience in security, platform, or infrastructure engineering.
Have designed secure systems end-to-end (not just reviewed them after the fact).
Are fluent in cloud security fundamentals (IAM, networking, KMS, secrets, isolation).
Have hands-on experience with Kubernetes and modern cloud environments.
Think in terms of threat models, trust boundaries, and failure modes.
Enjoy building paved roads and guardrails that help teams move fast safely.
Thrive in ambiguous, high-agency environments and want ownership of the security function as it grows.
