About Brain Co.
At Brain Co., we build AI systems that power mission-critical workflows for some of the world’s most important institutions. Our platform operates in high-stakes, highly regulated environments where security is not an afterthought — it is a core product requirement.
As a Security Engineer at Brain Co., you will design and build the security foundations that protect AI systems deployed inside governments, energy providers, and healthcare organizations. You will work across cloud infrastructure, application layers, and compliance-driven environments to ensure our platform is secure by default, auditable, and resilient at scale.
This is a foundational role on our Platform organization. You will partner closely with Infrastructure, AI/ML, and Product Engineering to embed security into how we design, ship, and operate systems — not bolt it on afterward.
