About The Position

We are seeking an experienced Migration Support Engineer to provide onsite execution, validation, and issue-resolution support for a multi-site user and device migration across nine (9) U.S.-based distribution centers. The role is 100% field-based for the duration of the engagement and works in close coordination with a remote migration consultant who runs the centralized cutover activities. You will be the on-the-ground execution resource: walking the floor of each DC, validating that workstations land cleanly in the target Active Directory and Microsoft 365 tenant, and troubleshooting Quest Desktop Update Agent (DUA) issues during scheduled wave cutovers and HyperCare.

Requirements

Proven experience supporting end-user computing migrations, workstation refreshes, or domain / tenant transitions.
Strong working knowledge of Active Directory and Windows workstation environments.
Hands-on experience troubleshooting user login, profile, and access issues.
Working familiarity with Microsoft 365 services from a troubleshooting perspective – Exchange Online, Outlook, OneDrive, Teams, SharePoint, and Intune-managed devices.
Familiarity with Quest On Demand Migration (ODM) and the Desktop Update Agent (DUA), or comparable migration tooling, is strongly preferred.
Strong troubleshooting skills with the ability to work calmly during live cutovers and HyperCare.
Excellent communication skills and the ability to work effectively with a remote technical team.

Nice To Haves

Prior experience supporting multi-site or geographically distributed migrations.
Experience working in warehouse, distribution center, or manufacturing environments and an understanding of shift-driven cutover windows.
Exposure to Okta, hybrid Exchange, PKI, or domain rewrite scenarios.
Ability to work independently and manage onsite priorities with minimal supervision.

Responsibilities

Provide onsite presence during scheduled wave cutovers, working systematically through the floor and shift areas in coordination with the remote migration consultant.
Validate that workstations are successfully migrated and joined to the target Active Directory and Microsoft 365 tenant, with full post-migration functionality (domain membership, GPO/Intune policy, sign-in, mail flow, Teams, OneDrive, SharePoint).
Execute pre-wave smoke tests and post-wave verification spot checks; contribute results to wave validation reporting.
Troubleshoot ODM and Desktop Update Agent (DUA) issues; remediate stalled or failed agents and escalate to the remote consultant where centralized action is required.
Support HyperCare monitoring of mail delivery, sign-in/auth, address policies, permissions, and device compliance for recently migrated users.
Serve as the primary onsite point of contact: coordinate with local DC site contacts on access and shift windows, document and escalate issues, and report daily progress to the migration lead.
