We are seeking a SharePoint Information Architecture and Governance Lead to lead the technical design, governance, and development of our SharePoint Online platform across a global footprint. This role combines information architecture ownership, governance program execution, hands‑on SharePoint Framework (SPFx) development, and ownership of the M365 backup platform.

The role also includes evaluating emerging AI capabilities (Copilot for Microsoft 365, SharePoint Agents) to enhance content discovery and knowledge management.
