AI Platform Engineer, Security

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.
