This includes designing intelligent, dynamic mechanisms for ephemeral access control, secrets management, and agent/user identity tailored to the

• Lead the evolution of MCPs and agentic AI, transforming innovative ideas into systems that define how intelligent agents operate at scale.
• Collaborate with architects and engineers to shape and deliver high-performance platform components you can take pride in.
• Write clean, maintainable, and scalable code that powers some of the world’s largest and most security-conscious companies.
