Active Directory / Identity Engineer (Journeyman)

About this role

Overview
DecisionPoint seeks an Active Directory / Identity Engineer to administer, sustain, secure, and recover the Microsoft Active Directory Domain Services environment supporting the USMEPCOM ENLIST program. This position manages AD objects, organizational units, Group Policy Objects, trusts, replication, schema changes, delegated permissions, domain services, and recovery capabilities.
The Active Directory / Identity Engineer provides direct, hands-on AD DS support while assisting with approved Identity, Credential, and Access Management initiatives. The engineer helps test potential Okta integrations and other identity-modernization technologies without reducing the program’s need for strong traditional Active Directory engineering and operational expertise.
The engineer works closely with the Senior AD/Identity Engineer, cybersecurity personnel, Service Desk, systems administrators, cloud and application teams, COOP personnel, and Government identity stakeholders. The position supports routine directory administration, complex troubleshooting, modernization testing, disaster recovery, and critical incident response.
This position is remote, with Chicago-area candidates preferred. Occasional after-hours maintenance, COOP exercises, incident response, on-site support, or travel may be required.
Note: By applying to this position, you acknowledge and consent to having your resume included in an active competitive government contract bid.

• Troubleshoot authentication, authorization, account, group-membership, policy, trust, replication, and directory-permission issues.

• Implement approved corrective and preventive actions resulting from incidents and problem reviews.

• Maintain and execute Active Directory backup and restoration procedures.

• Test system-state backups, deleted-object recovery, authoritative and non-authoritative restoration, and forest-recovery procedures.

• Support COOP exercises, disaster-recovery tests, recovery validation, and actual continuity events.

• Document recovery results, technical deficiencies, corrective actions, and lessons learned.

• Support testing of approved ICAM and identity-modernization technologies.

• Assist with integration testing between Active Directory and Okta or other Government-approved identity platforms.

• Validate identity synchronization, authentication flows, attribute mappings, group mappings, account linking, provisioning behavior, access controls, and error handling.

• Support testing involving approved federation and modern authentication protocols such as SAML, OpenID Connect, OAuth, SCIM, or LDAP.
