• Administer and support core business systems (Microsoft 365 GCC High, collaboration tools, ticketing systems, etc.)

• Manage users, permissions, groups, and access provisioning across tools

• Maintain system configurations, workflows, and basic automations

• Troubleshoot system issues and act as the primary point of contact for internal users

• Support administration of systems across multiple entities and international operations, ensuring consistency in access, configuration, and compliance requirements

• Support administration of a mixed Windows/Linux Microsoft 365 and Active Directory environment

• Execute access controls, conditional access policies, and device/user management

• Help maintain secure collaboration environments for sensitive data (ITAR / CUI)

• Partner with IT/security leadership on implementing security best practices including health monitoring, backup and recovery.

• Support ongoing CMMC compliance efforts by implementing required system updates and controls

• Execute changes related to CUI data handling, access restrictions, and audit readiness

• Maintain documentation, access logs, and system configurations for audits

• Partner with external consultants and internal leads to ensure controls are properly applied

• Help monitor and remediate compliance gaps across systems

• Support implementation and ongoing use of security monitoring tools (e.g., SIEM) by contributing logs, access data, and system context

• Support integrations and data consistency across tools (HRIS, finance systems, collaboration tools, etc.)

• Assist in maintaining data integrity, user lifecycle processes, and system hygiene

• Generate basic reports or exports to support compliance and business operations

• 3–6 years of experience administering enterprise SaaS tools in a business environment

• Strong experience with Microsoft 365 and Intune
