About The Position

3GIMBALS is seeking an experienced Counterintelligence (CI) Subject Matter Expert to provide direct, customer-facing support to the Naval Criminal Investigative Service (NCIS). The SME will apply extensive counterintelligence investigative and/or operational experience to support Research, Development, and Acquisition (RDA) protection, helping identify and mitigate foreign intelligence threats to sensitive technologies, programs, personnel, facilities, and activities.
