• ADFS SSO
• trust configuration
• RBAC mapping
• Security alignment

Systems Engineer's Responsibilities: -Lead the design and deployment of Active Directory forest and domain architecture, including multi-domain and multi-forest environments. -Architect and implement Active Directory Federation Services (ADFS) solutions to enable single sign-on (SSO) across classified and unclassified systems. -Design and configure cross-domain and cross-forest trust relationships in complex, segmented network environments. -Develop and enforce role-based access control (RBAC) frameworks, group policy objects (GPOs), and delegation models aligned with least-privilege principles. -Align directory services architecture with DISA STIG requirements, NIST 800-53 controls, and program-specific security policies. -Collaborate with cybersecurity teams to support ATO processes, RMF documentation, and identity-related continuous monitoring requirements. -Serve as the subject matter expert for identity and directory services, providing technical leadership and mentorship to junior engineers. -Troubleshoot and resolve complex Active Directory, ADFS, and identity federation issues across multi-domain environments. -Evaluate emerging identity and access management technologies and recommend solutions aligned with program roadmaps and government requirements. -Produce and maintain technical documentation including forest design diagrams, trust maps, RBAC matrices, and configuration baselines.

8-10+ years of hands-on experience in systems engineering with deep expertise in Active Directory architecture and identity management. -Demonstrated experience designing and deploying AD forest and domain structures in large-scale enterprise or government environments. -Strong working knowledge of ADFS, SSO federation protocols (SAML, OAuth, WS-Federation), and identity provider configuration. -Experience designing and managing cross-domain and cross-forest trust relationships in segmented or classified network environments. -Deep understanding of RBAC frameworks, GPO design, and least-privilege access models. -Working knowledge of DISA STIGs, NIST 800-53, and RMF as applied to directory services and identity infrastructure. -Active Top Secret security clearance required; TS/SCI eligibility strongly preferred., Prior experience supporting classified programs in a DoD, IC, or cleared defense contractor environment. -Familiarity with Azure Active Directory, hybrid identity architectures, and cloud identity integration. -Experience with Privileged Access Management (PAM) solutions such as CyberArk or BeyondTrust. -Familiarity with PKI infrastructure, certificate services, and smart card authentication in DoD environments. -Experience with PowerShell scripting for AD automation and administration. -Bachelor's degree in Computer Science, Information Technology, Systems Engineering, or a related field; equivalent experience considered.
