MEANINGFUL WORK AND PERSONAL IMPACT

As a Zero Trust ICAM & PKI SME, the work you do at GDIT will be impactful to the mission of supporting infrastructure security on the CITS contract for USCENTCOM. You will play a crucial role in leading the engineering, deployment, and operational integration of identity-centric, credentialing, and access control solutions across USCENTCOM’s network enclaves, aligned with DoW Zero Trust principles.

HOW A ZERO TRUST ICAM & PKI SME WILL MAKE AN IMPACT

Your responsibilities span across the three core ICAM pillars:

1. Identity Management (Identity Lifecycle & Directory Services)

• Design, implement, and maintain enterprise Identity Management solutions, prioritizing DISA’s enterprise solution to ensure seamless integration with Zero Trust architectures.
• Architect and manage Master User Records (MUR), directory services (e.q., Active Directory), and Automated Account Provisioning (AAP) pipelines.
• Troubleshoot complex identity synchronization, profile mapping, and lifecycle workflows across heterogeneous enclaves and mission partners.
• Build, deploy, and maintain identity connectors and integrations with enterprise HR/authoritative data sources and cloud environments.
• Maintain system documentation, data dictionaries, and SOPs for identity lifecycle management tasks.

2. Credentialing & PKI (Authenticators, Non-Person Entities & Cryptography)

• Design, engineer, and operate enterprise Public Key Infrastructure (PKI) solutions aligned with DoD/NSS PKI standards, CNSSP-1300, and CJCSM requirements.
• Configure, harden, and maintain Certification Authorities (CAs), Registration Authorities (RAs), Validation Authorities (OCSP), and Hardware Security Modules (HSMs).
• Architect and operationalize enterprise Certificate Lifecycle Management (CLM) processes, automating certificate issuance, renewal, and revocation across web servers, endpoints, and secure communication channels.
• Implement Network Device Enrollment and automated Non-Person Entity (NPE) credentialing utilizing protocols such as SCEP, EST, and ACME.
• Lead PKI-enablement for enterprise applications, network appliances, and workloads to enforce mutual TLS (mTLS) and smart-card/phishing-resistant MFA (CAC/PIV, hardware tokens).
• Maintain disaster recovery, business continuity, and key recovery/custody plans for cryptographic infrastructure.

3. Access Management & Governance (Authorization, Federation & PAM)

• Configure, enforce, and optimize fine-grained access control models, including Role-Based (RBAC), Attribute-Based (ABAC), Policy-Based (PBAC), and Identity-Based Access Control (IBAC).
• Lead the deployment and operational administration of Privileged Access Management (PAM) platforms (e.g., Delinea) to safeguard privileged accounts and enforce just-in-time access.
• Implement Identity Governance and Administration (IGA) solutions (e.g., SailPoint) for access certifications, segregation of duties (SoD), and role mining.
• Troubleshoot complex federation and Single Sign-On (SSO) integrations utilizing modern protocols (SAML 2.0, OAuth 2.0, OIDC).
• Collaborate with multi-disciplinary cybersecurity teams to enforce continuous authentication and dynamic authorization in line with Zero Trust principles.

Cross-Pillar Operations & Compliance

• Perform regular maintenance, vulnerability scanning, security STIG remediation, and patching across all ICAM and PKI server environments.
• Ensure strict adherence to DoD ICAM policies, DISA STIGs, FIPS cryptographic benchmarks, and DoD Zero Trust reference architectures.
• Interface with third-party vendors (e.g., F5, Microsoft, SailPoint, Delinea, Keyfactor, Thales) for tier-3/escalated troubleshooting.
• Produce management reports, audit metrics, compliance packages, and system administration runbooks.
