What You’ll Do

The Michelle Martin Group (MMG) is seeking a M365 SharePoint Support Specialist Contractor (GCC High) to support the administration, security, and improvement of a Microsoft 365 SharePoint Online environment. This role focuses on secure collaboration with external users, effective site governance, and practical solutions that support business needs while maintaining government cloud security and compliance expectations.

Job Summary

The M365 SharePoint Support Specialist will administer SharePoint Online in a GCC High environment, support secure guest access and external sharing, and help maintain governance and data protection controls. The specialist will collaborate with IT, security and compliance teams, and internal and external users to resolve issues, document processes, and improve collaboration. This is a temporary assignment expected to last approximately six months.

Key Responsibilities

• Administer SharePoint Online (GCC High): Design and build modern SharePoint sites, pages, lists, libraries, forms, workflows, and business solutions. Manage site collections, permissions, hub/site architecture, content lifecycle, and sharing settings in alignment with US Government cloud feature nuances and compliance expectations.  

• Enable secure external collaboration: Configure and operate guest workflows (inbound/outbound access, domain restrictions, invitation redemption), with an emphasis on GCC High/Azure US Government considerations.  

• Govern external sharing for SharePoint/OneDrive: Implement and tune organization‑ and site level external sharing policies (link types, expiration, domain allow/deny lists, auditing), and transition legacy sharing patterns to current best practices. 

• Apply DLP and governance: Create and maintain Data Loss Prevention policies, connector classifications, and environment scopes that protect sensitive data while enabling productivity. 

• Documentation & runbooks: Produce clear admin and user documentation (site standards, sharing procedures, guest management SOPs, Power Platform solution guides, technical manuals, and training materials). 

• Incident & request handling: Triage and resolve SharePoint/Power Platform issues; support periodic onboarding of external customer teams into the tenant using approved processes and controls; provide technical support to users, site owners, content managers, and project teams. 

• Security/compliance alignment: Manage security groups, access permissions, sharing settings, and governance controls in line with organizational policies. Collaborate with security teams to ensure configurations align with GCC High commitments (data residency, screened personnel access, and US Government cloud isolation).  

Qualifications

• Hands‑on SharePoint Online administration in M365 GCC/GCC High (site architecture, permissions, external sharing controls, search/content governance). 

• External sharing best practices in SharePoint/OneDrive: link types (Specific People, People in org), expiration, “Anyone” link restrictions, site-level overrides, and audit/monitoring. 

• Scripting & tooling familiarity (PowerShell modules for SharePoint/Power Platform admin, PPAC, SharePoint Admin Center) to automate routine tasks.  

• Strong communication skills for collaborating with external customers and internal stakeholders; ability to write SOPs and deliver brief training as needed.  

Preferred Skills

• Prior experience operating in US Government cloud tenants (GCC High) with awareness of feature differences vs. commercial (e.g., service availability nuances, cross‑cloud B2B prerequisites).  

• Experience balancing security and collaboration for external partners (project‑based guest access, least‑privilege site design, domain allow lists) and modernizing legacy sharing models.  

• Familiarity with Center of Excellence concepts (environment strategy, ALM pipelines, maker onboarding, monitoring/analytics) for the Power Platform. 

• Knowledge of DLP advanced patterns (connector actions, tenant baseline vs environment exceptions) and related PowerShell administration. 

• Experience coordinating with compliance teams regarding GCC High commitments (e.g., data residency, screened personnel access, eligibility). 

• Power Platform experience: Building and maintaining Power Apps (Canvas/Model‑driven preferred) and Power Automate flows that integrate with SharePoint and approved connectors.  

• Governance & DLP: Ability to design and enforce Power Platform DLP policies (tenant and environment scope, connector grouping, blocked actions) and articulate their impact to makers and stakeholders. 

Additional Requirements

• U.S. citizenship is required for this position.
