This role embeds security architecture directly into the Digital Journey Architecture and Solutions organization - providing the team with IAM and security expertise at the point of design, not as a downstream review function.The scope spans customer portal identity (who can access what and how), API security and authentication standards (OAuth2, OIDC, SAML), SSO integration (including Entra B2C for enterprise and government customers), FedRAMP and compliance-aligned security architecture, and the emerging security requirements of agentic AI systems. This role also serves as the primary DJAS interface for security architecture related to complex multi-cloud networking integrations and Lumen's public sector initiatives.
