Establish scalable approaches for working with identity providers across internal and platform systems. Authorization and access control Design and evolve authorization frameworks using models such as RBAC , ABAC , and policy-based access control. Drive consistent access patterns for complex, distributed systems where security and usability must both scale. Standardize policy-as-code and automation approaches for identity and access control enforcement. Workload identity and zero trust Build and scale service-to-service authentication and workload identity patterns, including short-lived credentials and identity-based access. Establish zero trust architecture principles and ensure they are enforced consistently across infrastructure. Define identity patterns for cloud , Kubernetes , and GPU-based infrastructure environments. Lead the design of privileged access management , secrets management , and secure access workflows. Cross-functional technical leadership Partner with infrastructure, platform, and security teams to integrate identity into core systems and services. Influence large-scale initiatives across organizational boundaries as a senior technical leader. Mentor senior engineers and raise the bar for security engineering across teams.
