Develop new concepts or standards which make significant and impactful improvements to processes, systems, solutions, or products
Provide tasking and guidance to ISSO team

Preferred Additional Skills:

Currently possess an active full scope polygraph
High level of personal motivation and initiative to learn and acquire new skills and a technical understanding of new technologies
9 years of prior relevant experience to include experience with networking equipment; experience interpreting vulnerability scanning results (e.g. Nessus, Rapid7, etc.); experience reviewing workstation, server, firewall, & IPS logs (e.g. Splunk); experience with SIEM, DLP, and/or UBA tools
Experience as an ISSM managing cybersecurity on classified systems under multiple agencies' JSIG, NISPOM Ch8, ICD 503, and/or NIST 800-53 implementations
Experience developing, managing, and providing evidence to close POA&Ms associated with the A&A and project management processes
Experience with diverse workstation and server operating systems, including but not limited to Microsoft and Linux offerings
