* Participate in capacity planning, system tuning, and performance optimization.
* Contribute to the continuous improvement of IT policies, standards, and support processes.

* Familiarity with virtualization technologies (i.e., VMware vSphere/ESX).
* Experience with system vulnerability scanning, patching, and remediation.
* Excellent communication and documentation skills.
* Willingness to provide occasional desktop and end-user support.
* DOD 8570 IAT Level II certification (i.e., Security+) or ability to obtain within 6 months.
* Experience managing RedHat-based systems with RedHat Satellite and Ubuntu systems using Canonical Landscape is preferred.
* Experience supporting classified environments and working with DoD or federal agency partners is a plus.
* Hands-on experience with encryption protocols for securing data at rest and in transit is advantageous.
