Job Description

Advance how our customers operate while you advance your career. Join GDIT as a Zero Trust ICAM & PKI SME and build an impactful career in enterprise IT, collaborating with people who are driven and resourceful like you.

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 DoD Zero Trust principles.

How a Zero Trust ICAM & PKI SME will make an impact

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.
