U.S. citizenship and an active Secret clearance are required to start; the candidate must be eligible to obtain and maintain TS/SCI clearance.

The MECM Administrator will architect and sustain MECM (formerly SCCM) infrastructure across distributed and bandwidth-constrained networks. The role leads enterprise patching and compliance, software distribution, operating system deployment, reporting, complex endpoint issue resolution, documentation, and mentorship.

The ideal candidate brings substantial systems administration and direct MECM/SCCM experience, strong PowerShell automation, and practical knowledge of server hardware, virtualization, and network infrastructure. Experience supporting large endpoint fleets and secure DoD operating environments will help the team deliver reliable, compliant services.

Responsibilities include but are not limited to:

 * Architect, configure, maintain, and troubleshoot MECM (formerly SCCM) infrastructure, including Primary Sites, Management Points, and Distribution Points.
 * Support MECM operations across distributed and bandwidth-constrained networks.
 * Lead the enterprise patching strategy for Microsoft operating systems and third-party applications.
 * Plan and track timely vulnerability remediation in line with security requirements, including DISA STIGs and Information Assurance Vulnerability Management (IAVM) directives.
 * Package, test, and deploy complex software applications, updates, and custom PowerShell scripts to tens of thousands of endpoints while minimizing user disruption.
 * Engineer and maintain operating system deployment (OSD) baselines, task sequences, boot images, and driver packages.
 * Support zero-touch provisioning, bare-metal imaging, and in-place Windows upgrades.
 * Develop custom SQL queries, SQL Server Reporting Services (SSRS) reports, and CMPivot queries that show endpoint health, compliance metrics, and deployment status.
 * Serve as a Tier 3 escalation point for complex endpoint and deployment issues.
 * Create and maintain detailed technical documentation and standard operating procedures (SOPs).
 * Mentor junior system administrators and share operational knowledge across the team.
