About Brooks McMillin

I'm an Infrastructure Security Engineer at Dropbox, leading a team focused on AI agent security, LLM development tooling, and securing production AI systems. My work spans building security frameworks for autonomous agents, securing authentication flows, and driving infrastructure security strategy.

Professional Background

Current Role: Infrastructure Security Engineer at Dropbox

I lead a team of four focused on securing Dropbox's infrastructure and AI systems:

  • AI Agent Security Frameworks — Designing and implementing security architectures for autonomous AI agents, including sandboxing, permission models, and runtime monitoring
  • LLM Development Tooling — Building internal security tools that help engineers safely integrate LLMs into products, with guardrails for prompt injection, data leakage, and model abuse
  • OAuth & Identity Flows — Securing authentication and authorization across services, with a focus on token lifecycle management and least-privilege access patterns
  • Security Strategy — Driving the team's roadmap for infrastructure security priorities, threat modeling, and cross-functional security initiatives

Prior to this role, I built experience across infrastructure engineering, cloud security, and production systems, which informs my current focus on securing the intersection of traditional infrastructure and emerging AI capabilities.

Contact Information

I'm always eager to connect with fellow security researchers, autonomous systems enthusiasts, and anyone interested in the intersection of security and emerging technologies.
