SITEC is seeking a Systems Security Engineer who would like to join our team in support of the customer. The Security Engineer would be responsible for supporting the customer as part of a small team co-located between Colorado Springs, CO and Annapolis Junction, MD. This will require close collaboration and interaction with team members between the two sites. The team interfaces directly with government leadership of the agency’s Technology Solutions Division. Candidates must have experience supporting senior government representatives and have strong communication skills.
