Principal Architect - Identity, Access, and Management

Lumen is the trusted network for the AI-powered world, connecting people, data, and applications through our expansive fiber network and connected ecosystem. We enable secure, high-performance connectivity across cloud, edge, and AI workloads for enterprises, governments, and communities. At Lumen, you’ll work on infrastructure customers rely on today and build for what’s next, where performance, security, and resilience matter. This is a high accountability environment where bold ideas drive real innovation for our customers, partners, and industry. The work is challenging, expectations are clear, and trust is built into how we operate. If you’re ready to take ownership, deliver meaningful impact, and help shape the future of AI-ready connectivity, join us today. The Role Define and own identity, access management, and securityarchitecture 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 accesspatterns 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 (EntraB2C).

Develop IAM governance frameworks: RBAC/ABAC models, access lifecycle, entitlement review, auditevidence.

Define IAM-as-Code practices: Terraform-based identity configuration, version-controlled, auditable

Architect security for agentic AI systems: agent authentication, authorization boundaries, audit trails forAI-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 andsecurity 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 securityperspective regardless of work type.

Partner with Lumen’s Security team (not owned by DJAS) and bring the security perspective into DJASdesign 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 anddesign 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 orimproved their work.

CISSP, CISM, or equivalent security certification preferred

Deep expertise in enterprise IAM architecture: Microsoft Entra ID/Azure AD, AWS IAM - productionscale

Expert knowledge of OAuth 2.0, OpenID Connect, and SAML - not just implementation but architectureand 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, FedRAMPHigh/Moderate)

Understanding of compliance frameworks across multiple regulators: ISO 27001, SOC 2, PCI-DSS,GDPR
