Brain-computer interface expands new possibilities for life.
About the role
As our Security Engineer, Application & AI, you will own the security of our products and application layer — secure development practices, agent security, third-party integration security, and data protection for AI products operating in some of the world's most regulated and sensitive environments.
What they're looking for
- Have 5+ years of experience in application security or product security, with hands-on experience on production systems at scale
- Are a builder first — you write code and ship security tooling, and see embedding security into the engineering workflow as the job, not a side effect of it
- Have deep fluency in application security fundamentals: OWASP Top 10, AuthN/AuthZ, secure SDLC, secrets management, secure integration patterns, and cryptography basics
- Understand the security surface of agentic AI across the product layer — how agents should be designed, scoped, and reviewed for risk — and can work shoulder-to-shoulder with engineers to build those standards in
- Have experience protecting sensitive data at the application layer: access controls, audit logging, and preventing data exposure through third-party integrations and AI-generated outputs
- Work AI-natively — you already use AI to write better code, move faster, and do more with less, and you bring that same instinct to security work
More about this role
Rebuild how the world works, to make institutions work better for the people they serve.
Brain Co. builds AI-native operating systems for large, regulated institutions. Each system is built for a specific industry, powered by agents that push real workflows forward. Underneath it all is Atlas, our proprietary platform that keeps customers in control, secure by design, and never locked into one model.
Brain Co. is entering its next phase of production deployments on a national scale with an elite team built from Palantir, Google, Meta, and Nvidia, and a growing footprint across government, insurance, health, and financial services.
Joining now means shaping both the company and a new category of applied AI. Every project here ships to production and is expected to create measurable customer value and impact.
You'll work alongside exceptional peers on some of the hardest problems in applied AI. It’s the kind of work you'll still be proud of in ten years from now.
