Trillium Professional is now seeking an IAM Platform Administrator in Richmond !

We are seeking a seasoned and proactive IAM Platform Administrator to lead the design, integration, and operational support of our enterprise-wide Identity and Access Management (IAM) ecosystem. This role is critical in shaping and maintaining a secure, scalable identity architecture across hybrid environments-spanning on-premises Active Directory, Microsoft Entra ID, and federated cloud services (Azure, AWS, M365, and more).

You will play a key role in implementing modern identity solutions, enabling seamless authentication, secure access, and governance aligned with zero-trust principles.

KEY RESPONSIBILITIES:

In addition to other occasional tasks, the candidate's key responsibilities will be:

• Design and maintain identity architecture across on-premises AD, Microsoft Entra ID, and federated cloud platforms (Azure, AWS, M365).
• Implement and manage hybrid identity solutions, including seamless SSO, passwordless authentication, and conditional access policies.
• Automate identity lifecycle processes (provisioning, deprovisioning, role transitions) using PowerShell, Microsoft Graph, and Entra ID Governance.
• Integrate third-party applications with Entra ID using SAML, OAuth2, and OpenID Connect protocols.
• Monitor and troubleshoot authentication flows, device join states, token issuance (PRT), and MFA challenges.
• Administer and support IAM components, including SSO, MFA, conditional access, and self-service password reset.
• Manage user lifecycle operations (Joiner-Mover-Leaver) across AD, Entra ID, and Okta, ensuring accurate role-based access.
• Provide production-level support for Active Directory infrastructure, including domain controllers, replication, trust relationships, and GPOs.
• Design and maintain automation scripts (PowerShell, Python, Bash) for bulk provisioning, reporting, and account cleanup.
• Collaborate with security and compliance teams to enforce least privilege, RBAC, and Just-In-Time access models.
• Monitor IAM systems for performance issues, outages, and anomalies, and respond swiftly to incidents.
• Collaborate with IT and helpdesk teams to resolve authentication and access-related issues.
• Document and maintain SOPs, escalation ladders, and architectural diagrams for identity services.
• Stay current on evolving identity threats, zero trust architecture, and Microsoft roadmap updates.
• Develop and deliver user training and support for IAM tools and workflows.

QUALIFICATIONS:

• • 10+ years of hands-on experience in IAM, IT security, or infrastructure administration.
  • Deep expertise in Microsoft Entra ID (Azure AD) and Okta, including hybrid identity, federation, and synchronization.
  • Strong proficiency in Active Directory administration, including GPOs, replication, and domain controller management.
  • Proven experience managing access via roles, groups, and entitlements across web, cloud, and service-based environments.
  • Skilled in lifecycle operations: provisioning, updates, suspension, and de-provisioning of identities.
  • Experience with IAM automation and scripting using PowerShell, Microsoft Graph, or similar tools.
  • Strong troubleshooting skills across IAM components and authentication protocols.
  • Demonstrated ability to detect and respond to IAM-related security incidents.

PREFERRED QUALIFICATIONS:

• • Experience managing hybrid identity environments, integrating on-prem AD with cloud IAM platforms.
  • Certifications such as Security+, CISSP, Okta Certified Administrator, or Microsoft Entra Certified.
  • Familiarity with federated identity protocols (SAML, OAuth2, OpenID Connect).
  • Working knowledge of identity synchronization tools (e.g., Microsoft Entra Connect, Okta AD Agent).
  • Hands-on experience with IAM migration projects from on-prem to cloud.
  • Exposure to Identity Governance & Administration (IGA) and Privileged Access Management (PAM) solutions.
  • Experience generating audit and compliance reports aligned with SOX, HIPAA, and ISO 27001.
  • Strong troubleshooting across multi-platform authentication (.NET, Java, cloud-native apps).
  • Understanding of cloud and on-prem security best practices (Azure, AWS, GCP).
