Senior Microsoft 365 & IT Systems Administrator (Long-Term, Native English Required)

We are a 50-employee company that recently migrated from Google Workspace to Microsoft 365.

The migration is complete, but our Microsoft 365 environment requires a full audit, restructuring, and proper policy setup.

We are looking for a senior-level Microsoft 365 & Systems Administrator to:

Review our current configuration

Identify structural and policy issues

Propose and implement best-practice governance

Establish scalable policies for long-term growth

Provide ongoing structured IT support

This is a long-term collaboration reporting directly to the IT OPS & AI Director.

Communication quality is critical. Native English fluency is mandatory.

Current Challenges (Examples):

Microsoft 365 / Teams

Teams meeting recordings not starting automatically

Recordings not easily shareable across the organization

External communication restrictions

Calendar visibility policies (we want organization-wide visibility of busy/free without details)

Permissions & governance inconsistencies

External sharing configuration clarity

Storage / Migration

We currently have:

~12TB of data in Google Shared Drives

Need to migrate to:

Microsoft (SharePoint / OneDrive / Teams), OR

A third-party storage solution that integrates seamlessly with Microsoft 365 but at same or lower cost than Google Drive (Google Workspace Business Standard 2TB/user)

We are aware of Microsoft's 1TB per-user limitation and need an expert to design the correct architecture (SharePoint libraries, pooled storage, etc.).

We do NOT want improvised solutions — we want a properly architected system.
