What you'll do: Design, develop, and maintain reusable frameworks, libraries, APIs, and reference implementations for zero trust authentication and authorization. Create developer guides, documentation, and best practices to enable smooth integration with security services. Implement and support fine-grained authorization patterns (entitlements, row-level security, ABAC). Collaborate with architects and engineers to ensure security services meet performance, usability, and compliance requirements. Conduct code reviews and provide guidance to development teams on secure coding and integration practices. Research emerging zero trust and identity/access management technologies to recommend improvements.
