Principal Network Administrator - Top Secret

This position supports the Classified Solutions team by leading network architecture, integration, migration, security, and lifecycle efforts for large-scale, multidomain environments. The administrator will establish network standards, oversee monitoring and compliance, resolve advanced infrastructure issues, and provide technical guidance to customers, leadership, and project teams. The role also includes mentoring other engineers, coordinating vendors, tracking operational performance, and developing resilient solutions involving technologies such as SD-WAN, Zero Trust, cloud networking, routing, switching, firewalls, and encryption. It suits an experienced network engineer who is comfortable serving as a senior technical authority in classified government programs and communicating with both technical and nontechnical stakeholders. Candidates must be willing to work onsite, handle equipment and occasional nonstandard hours, and maintain the required security and special-program access.
