Your greatest work is ahead! (3rd Impact Statement)
We are seeking a Senior Systems Engineer responsible for the design, build, integration, and lifecycle management of Windows-based systems within complex enclave environments. This role focuses on delivering and sustaining reliable, secure, and interoperable system capabilities across Windows server infrastructure, domain services, and integrated COTS applications.
The position centers on Windows domain engineering, including Active Directory administration, Group Policy architecture, and integration of core services such as Citrix, Microsoft Exchange, and Microsoft SQL Server. The role also includes support for endpoint security enforcement using Trellix ePolicy Orchestrator (ePO), as well as certificate and PKI services that support authentication and secure communications across systems.
This environment consists of multiple independent systems and domains supporting a wide range of COTS and engineering applications. These may include collaboration and workflow tools (such as Jira, Confluence, and SharePoint) as well as engineering platforms (such as SolidWorks and MATLAB). Deep expertise in any single application is not required; success in this role depends on the ability to integrate and sustain interoperability across diverse systems.
The role requires strong engineering discipline, the ability to manage multiple concurrent efforts, and the flexibility to support both design and operational activities as needed.
