Provide technical direction during cutover windows and deliver support to stabilize services following implementation.

Act as the primary technical advisor for Microsoft 365 architecture, integration strategy, and risk reduction best practices.

Requirements

At least 7 years of experience engineering and supporting enterprise-scale Microsoft 365 environments.

Demonstrated success leading tenant-to-tenant Microsoft 365 migrations in merger, acquisition, or large integration scenarios.

Strong hands-on knowledge of Azure AD or Entra ID, Exchange Online, SharePoint Online, OneDrive, and Microsoft Teams.

Required experience using PowerShell to automate administration, migration tasks, and environment standardization.

Solid understanding of identity and access management principles, security controls, and compliance requirements within Microsoft 365.

Ability to evaluate architectural options, recommend practical solutions, and explain technical trade-offs clearly to stakeholders.

Comfortable working as a senior individual contributor in a highly hands-on role without direct people management responsibilities.
