We are seeking a Systems Engineer to support the design, integration, and sustainment of Windows-based systems within complex enclave environments. This role operates between Tier 2 support and senior engineering, serving as a key escalation point while developing deeper engineering capability.

The position focuses on Windows infrastructure, including Active Directory, Group Policy, and Windows Server environments, along with integrated platforms such as Citrix, Microsoft Exchange, and Microsoft SQL Server.
