Job Description
Active Directory / Entra ID / IAM Engineer
Location: NYC, Jersey City, or Pittsburgh (2-3 days onsite)
Duration: 12-month engagement
Seeking an experienced Active Directory / Entra ID / IAM Engineer to support enterprise identity and access management services across production environments. This role is focused on maintaining and enhancing on-premises and cloud-based identity infrastructure, with deep emphasis on Active Directory, Microsoft Entra ID, hybrid identity operations, authentication services, and privileged access controls.
Key Responsibilities
  • Provide day-to-day engineering and operational support for enterprise Active Directory and Entra ID environments supporting large-scale global user populations.
  • Administer, harden, and support on-premises Active Directory infrastructure including domain controller build and maintenance, DNS (SRV records), LDAP, Kerberos, NTLM, GPO, OU structure, replication, and directory health.
  • Support Microsoft Entra ID administration including Conditional Access, MFA, Identity Protection, Privileged Identity Management (PIM), app registrations, and service principal governance.
  • Maintain and support hybrid identity environments including AD Connect configuration, sync operations, failover between data center instances, and PowerShell-based sync troubleshooting.
  • Administer PKI infrastructure including certificate authority management, certificate lifecycle, LDAP signing, and certificate installation on domain controllers and services.
  • Support authentication and access solutions including SSO, federation (SAML, OIDC, OAuth2), MFA, and privileged access controls.
  • Perform enterprise application onboarding and integration with identity platforms; troubleshoot authentication, authorization, and provisioning issues.
  • Execute platform hardening aligned with Microsoft cumulative hardening guidance and enterprise security policy — including SMB signing, LDAP signing, Kerberos enforcement, and legacy protocol disablement.
  • Support audit, compliance, and vulnerability remediation activities; respond to security findings from scanning tools such as Rapid7, Nessus, or CrowdStrike.
  • Partner with infrastructure, cybersecurity, and application teams to deliver identity-related changes and service improvements.
  • Develop and maintain runbooks, operational documentation, and support procedures; train follow-the-sun operations teams on repeatable workflows.
  • Participate in on-call rotations, after-hours change windows, and incident response including major incident bridge management.
  • Use PowerShell, Python, and Microsoft Graph / Entra APIs to automate operational tasks and improve efficiency.
Required Skills & Experience
  • 8+ years of hands-on experience administering and supporting enterprise Active Directory — including building, hardening, and directly owning domain controllers.
  • Knowledge of AD fundamentals: Kerberos and NTLM authentication protocols, DNS (SRV records), LDAP and LDAP signing, GPO design, replication, forest/domain architecture, and DC security hardening.
  • Strong experience with Microsoft Entra ID including Conditional Access, MFA, Identity Protection, PIM, app registrations, and service principal governance.
  • Hands-on experience with AD Connect in high-availability configurations including multi-data-center failover, sync troubleshooting, and PowerShell-based sync commands.
  • Experience supporting hybrid identity environments across on-premises Active Directory and Microsoft Entra ID.
  • Working knowledge of PKI infrastructure including certificate authority administration, LDAP signing, and certificate use cases on domain controllers.
  • Experience with IAM and PAM platforms such as SailPoint, Okta, and CyberArk.
  • Proficiency in PowerShell; Python and Microsoft Graph API experience preferred.
  • Experience with enterprise SIEM platforms (Splunk preferred) for log analysis, dashboard use, and incident triage.
