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 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.

WHAT YOU’LL NEED TO SUCCEED

Bring your technology expertise and drive for innovation to GDIT. The Zero Trust ICAM & PKI SME must have:

• •Clearance: Active Secret
• •Citizenship: U.S. Citizenship required
• •Education: Bachelor's Degree in a related discipline (Cybersecurity or Information Assurance concentration preferred) or six (6) years of real-world or military experience in information assurance, network security, or systems administration.
• •Certification: Applicable DoW 8140 / DoW 8570 IAT Level II/III or IAM Level II/III Certification (e.g., Security+ CE, CASP+, CISSP) along with relevant role-based credentials (e.g., CIAM, CIGE, CIMP, Microsoft Certified: Identity and Access Administrator Associate, or Okta Certified Professional).
• •Experience: 10+ years of related engineering and operations experience in enterprise IT and cybersecurity.

Technical Competencies by Pillar

1. Identity Management

• •10+ years of experience in enterprise identity architectures and directory infrastructure (Active Directory, LDAP).
• •Deep understanding of Master User Records (MUR), Identity Governance & Administration (IGA platforms such as SailPoint), and automated provisioning workflows.
• •Familiarity with DISA enterprise identity solutions and federal identity federation models.

2. Credentialing & PKI

• •In-depth expertise in Public Key Infrastructure (PKI) concepts: X.509 certificates, CA trust hierarchies, Certificate Revocation Lists (CRLs), and Online Certificate Status Protocol (OCSP).
• •Hands-on engineering experience administering enterprise CA platforms (e.g., Microsoft AD CS, Keyfactor) and integrating with DoD/Federal PKI (FPKI).
• •Direct experience with Certificate Lifecycle Management (CLM) tools and automated enrollment protocols (SCEP, EST, ACME).
• •Experience with CAC/PIV middleware, hardware tokens, and Hardware Security Modules (HSMs) (e.g., Thales/SafeNet).

3. Access Management & Governance

• •Advanced proficiency in designing and implementing access control models (RBAC, ABAC, PBAC, and IBAC).
• •Hands-on experience configuring and managing Privileged Access Management (PAM) suites (e.g., Delinea).
• •Strong understanding of modern authentication protocols and federation mechanisms (SAML 2.0, OAuth, OpenID Connect, Kerberos, mTLS).
• •Proven experience supporting Zero Trust policy enforcement points (PEP) and policy decision points (PDP).

Desired Skills & Qualifications

• •Microsoft Windows Hybrid Administrator or ITIL 4 Foundation Certification.
• •Operational familiarity with USCENTCOM mission networks, enclaves, and operating environments.
• •Scripting and automation proficiency (PowerShell, Python, or Bash) for automating identity provisioning and certificate management workflows.
• •Experience integrating mTLS and certificate validation within enterprise API gateways, microservices, and reverse proxies.
• •Proven ability to author system architecture documents, CONOPS, disaster recovery runbooks, and engineering implementation guides.
