The Opportunity

CACi is seeking an experienced Senior Architect to provide technical leadership for large-scale Department of Defense (DoD), U.S. Space Force, Intelligence Community (IC), and Federal Civilian modernization programs supporting secure communications, enterprise IT infrastructure, satellite ground systems, and mission-critical network architectures.

The Senior Architect will serve as the principal technical authority responsible for developing innovative, scalable, and secure enterprise solutions supporting complex government acquisitions from opportunity identification through proposal development, system implementation, transition, and operations. This individual will lead technical strategy, solution architecture, systems engineering, and technical execution across multiple programs while collaborating with customers, program managers, chief engineers, capture managers, and engineering teams to deliver resilient, mission-focused capabilities. The position requires an exceptional combination of systems engineering expertise, satellite communications experience, enterprise networking, cybersecurity, cloud technologies, and infrastructure modernization.

The ideal candidate possesses direct experience leading the engineering and deployment of globally distributed satellite ground infrastructure, including Ka-Band Ground Entry Points (GEPs), S-Band antenna systems, and Optical Ground Terminals (Laser Communications) supporting next-generation military satellite constellations.

Responsibilities Include

• Serve as a principal Architect, leading technical strategy, architecture development, and engineering execution for large-scale defense, intelligence, and national security programs.
• Lead multidisciplinary engineering teams through the design, integration, modernization, deployment, and sustainment of enterprise IT, secure communications, and satellite ground systems.
