Active Directory Engineer

Job Description

A client of Insight Global is seeking a highly skilled Active Directory Engineer to join their Cloud Infrastructure / Identity team. This is an engineer-level, hands-on role (not an architect-only position). You’ll step into a large, complex on‑prem Active Directory environment that has grown over many years and includes legacy domains from past acquisitions/mergers. The environment is hybrid (on‑prem AD integrated with Entra ID) and needs stabilization, modernization, and cleanup.

This role is ideal for someone who enjoys “getting into the weeds,” improving imperfect systems, and helping shape how the environment should operate going forward. The team is looking for an engineer who is comfortable with ambiguity, enjoys problem-solving, and is excited to help re-engineer and optimize identity infrastructure.

Key Responsibilities:

• Clean up, stabilize, and improve an existing enterprise Active Directory environment.

• Support and execute Active Directory migration and optimization efforts across workstations, servers, and applications with minimal disruption.

• Troubleshoot and remediate complex AD issues, including replication, DNS, schema, trusts, domain controllers, GPOs, and legacy performance problems.

• Assess AD health and drive improvements across multi‑domain and multi‑forest environments.

• Support hybrid identity operations, including on‑prem AD integration with Entra ID and directory synchronization tooling.

• Build and maintain PowerShell automation to improve AD health, compliance, and operational consistency.

• Implement and reinforce tiered security / tiered administration practices, least‑privilege access, and auditing standards.

• Collaborate with cross‑functional teams to assess dependencies, mitigate risk, and execute changes in a controlled manner.

• Partner with IAM stakeholders to support governance workflows and understand how SailPoint integrates with AD for access lifecycle management (joiner/mover/leaver, provisioning, deprovisioning).
