About The Position

Advanced Technology Systems Company (ATSC), a federal contractor supporting U.S. defense and homeland security missions, is seeking a hands-on Principal Systems Architect to lead architecture, integration, testing, and technical execution of advanced C4ISR/C5ISR, border and perimeter surveillance, and Counter-UAS systems. The role translates customer mission needs into scalable system architectures and top-level designs that integrate technologies such as sensors, communications, command and control, networking, AI/ML, cybersecurity, and edge computing. The architect works closely with engineering teams, customers, Program Managers, Business Development, and external partners from concept through deployment and operational acceptance. The position provides end-to-end architectural leadership and hands-on technical direction across multidisciplinary teams; guides integrated hardware and software systems through development, production, deployment, and sustainment; and leads system-level integration, verification, validation, testing, demonstrations, field trials, and customer acceptance activities. The role also serves as a senior technical authority in customer engagements, technical reviews, proposals, and business development activities. The position is based on-site in either Gilbert, Arizona, or McLean, Virginia. Applicants must be U.S. citizens and eligible to obtain and maintain a U.S. government security clearance.
