M365 ​/ Collaboration Platform Administrator

Description

This role is contingent upon a contract award.

ICF is seeking an M365 / Collaboration Platform Administrator to configure, govern, and maintain the Microsoft 365, Google Workspace, and SaaS productivity platform environment for a federal technology program. Reporting to the Cloud / Enterprise Architecture Lead, this role owns tenant configuration, data protection settings, SaaS platform governance, and Power Platform administration across a broad portfolio of collaboration and productivity tools.

The ideal candidate has deep experience hardening and operating M365 and SaaS environments in federal settings. The right candidate understands how to configure collaboration platforms securely at scale, govern low-code tooling without blocking adoption, and keep tenant settings audit-ready without constant manual intervention.

This is a remote-friendly position with occasional onsite requirements in the Washington, DC Metro area.

This position requires that the job be performed in the United States. If you accept this position, you should note that ICF does monitor employee work locations and blocks access from foreign locations/foreign IP addresses and also prohibits personal VPN connections.
