We are seeking a highly motivated and skilled Cross Domain Solutions (CDS) Systems Administrator with 3–5 years of experience to join our Federal Systems Team as a key contributor to our high-performing Classified IT operations. This is an on-site role supporting mission-critical environments.

The ideal candidate brings a strong aptitude for learning, an exceptional ability to troubleshoot complex systems, and a deep commitment to maintaining the integrity and security of classified environments.
