Key Experience:

Responsibilities:

• Work directly with IT leadership & individual business unit IT site administrators & vendor-partners to establish a practical, secure, and supportable architecture enabling cross-company calendar free/busy, identity collaboration, and controlled SharePoint/OneDrive file and folder sharing, while maintaining appropriate CMMC and data-segregation requirements.
• Assess the current Microsoft 365, Entra ID, Exchange Online, SharePoint, and security configurations across the three production tenants.

• Establish appropriate Conditional Access, MFA, guest/external-user, access-control, and least-privilege policies.
• Establish security groups and governance mechanisms for cross-company collaboration.
• Ensure the architecture appropriately separates general corporate/non-CUI collaboration from GCC High CUI enclave.
• Review the implications of the newly acquired domain and recommend an appropriate corporate identity/namespace strategy.
• Assess the deprecated AdTech Commercial tenant for any remaining dependencies and recommend/assist with retirement where appropriate.
• Document the resulting architecture, configuration, security controls, administration procedures, and ongoing support requirements.
• Provide knowledge transfer to staff and leave the environment fully supportable after completion.

  • Microsoft 365 GCC / GCC High
  • ITAR/EAR environments
  • Security boundary and data-flow considerations.
