Principal Architect - Identity, Access, and Management

The Role

Define and own identity, access management, and security architecture for Lumen's NaaS platform,
customer-facing digital services, and AI/agent ecosystems. 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.

Location

This is a remote opportunity open to candidates located anywhere in the U.S.

The Main Responsibilities

• Own IAM strategy and target-state architecture across Lumen's NaaS identity ecosystem:
  LIAM/ECAPS, Microsoft Entra ID/B2C, AWS IAM.
• Design and operationalize Zero Trust identity principles: continuous verification, risk-based access,
  least privilege enforcement.
• Architect customer identity and access management (CIAM): web portal, mobile, and API access
  patterns with security and customer experience in balance.
• Define authentication and federation standards: OAuth 2.0, OpenID Connect, SAML - enforced across
• APIs and customer-facing surfaces.
• Design SSO architecture across NaaS portal, partner portals, and government-facing services (Entra
  B2C).
• Develop IAM governance frameworks: RBAC/ABAC models, access lifecycle, entitlement review, audit
  evidence.
• Define IAM-as-Code practices: Terraform-based identity configuration, version-controlled, auditable
• Architect security for agentic AI systems: agent authentication, authorization boundaries, audit trails for
  AI-generated actions, token lifecycle management for agents.
• Provide security architecture for FedRAMP-aligned government initiatives: boundary preservation,
  tokenization patterns, identity flow compliance.
• Serve as the embedded DJAS security architect for multi-cloud networking integration: define IAM and
  security boundary requirements across cloud-to-cloud and cloud-to-physical network interconnects
• Conduct security architecture reviews on NaaS designs: threat modeling, attack surface analysis,
  risk-based recommendations.
• Define security NFRs for DJAS architecture work: what every design must address from a security
  perspective regardless of work type.
• Partner with Lumen's Security team (not owned by DJAS) and bring the security perspective into DJAS
  design work proactively.

What We Look For in a Candidate

• Bachelor's degree in computer science, engineering, information security, or related field with 12
  years of relevant experience or
• Master's degree with 10 years of relevant experience
• AI-first practitioner - actively integrates AI tools (LLMs, coding assistants, AI-powered analysis and
  design tools) as a routine part of architecture and engineering work, not as an occasional experiment.
• Candidates must demonstrate specific, current examples of how AI has meaningfully accelerated or
  improved their work.
• CISSP, CISM, or equivalent security certification preferred
• Deep expertise in enterprise IAM architecture: Microsoft Entra ID/Azure AD, AWS IAM - production
  scale
• Expert knowledge of OAuth 2.0, OpenID Connect, and SAML - not just implementation but architecture
  and standards governance
• Customer identity (CIAM) experience: portal, mobile, and API access patterns
• Zero Trust architecture principles and implementation experience
• RBAC/ABAC model design at enterprise scale
• FedRAMP, FISMA, or NIST 800-53 compliance architecture experience
• Security architecture for API ecosystems: API gateway security, token management, key rotation,
  scope enforcement
• Threat modeling disciplines (STRIDE or equivalent)

Preferred:

• Experience securing agentic AI systems or autonomous workflow platforms
• Microsoft Entra B2C (government/B2C federated identity) experience
• Experience with multi-cloud networking security or cloud-to-physical network security boundaries
• (SD-WAN, SASE, network security gateways)
• PAM (Privileged Access Management) architecture experience
• IAM-as-Code: Terraform-based identity configuration management
• Government/Public Sector cloud security architecture experience (GovCloud, FedRAMP
  High/Moderate)
• Understanding of compliance frameworks across multiple regulators: ISO 27001, SOC 2, PCI-DSS,
  GDPR
