About The Position

CACI is seeking a mid-level Systems Engineer to support Operations and Maintenance (O&M), limited Research and Development (R&D), and procurement of data and information-processing capabilities under the SCION IV contract. This role supports the United States Space Force Combat Forces Command (CFC) within a fast-paced, mission-driven operational environment This is an execution-focused role supporting operational systems You will work as part of an interdisciplinary engineering team providing direct support to operational units across the globe. The role blends systems engineering discipline with hands-on execution, supporting real-world mission systems rather than purely theoretical designs You will provide engineering expertise across a varied set of hardware, software, and expeditionary equipment. Communicate highly technical information to all levels of the USSF’s CFC teams and subordinate units You will have the opportunity to work with both co-located and remote engineering teams across the globe, along with providing on-site support to exercise events throughout the year

Requirements

Active TS/SCI clearance (polygraph may be required for Special Access Programs)
Bachelor’s degree in a STEM discipline with 2–4 years of relevant experience, or 7+ years of relevant experience in lieu of a degree
Willingness to learn, teach, and share information in both co-located and distributed team environments
Working understanding of RF systems, including design, propagation, and receiver performance
Knowledge of systems engineering fundamentals applied to operational environments
Experience producing technical documentation such as technical volumes, white papers, and version description documents
Strong attention to detail, active listening skills, and clear written and verbal communication
Self-motivated and able to work independently at remote or operational sites
Ability to lift 50+ pounds to support system installation, testing, and pack-out activities

Nice To Haves

Exposure to the Systems Engineering Body of Knowledge (SEBoK) and interest in advancing SE best practices within USAF customer environments
Experience integrating subsystems into larger systems (e.g., aircraft, ground vehicles, ships, fixed installations)
Experience with antenna system maintenance, sub-system repair, or depot-level support
Hands-on experience with RF measurement and test equipment
Exposure to SIGINT production systems
Familiarity with networking principles and experience working with classified networks
Understanding of DoD acquisition practices
DoD 8570.01 IAT Level II certification (Security+ or equivalent)
Systems Engineering or Project Management certifications (ASEP, Project+)

Responsibilities

Provide Operations and Maintenance (O&M) support for operational systems, including large fixed antenna systems, portable and expeditionary antenna systems, and associated RF and test equipment
Troubleshoot RF, power, networking, and software issues affecting system availability or performance
Perform hands-on system installations, upgrades, and sustainment at geographically dispersed locations
Configure systems to meet mission- and customer-specific requirements, often under time constraints
Investigate degraded or intermittent system performance and execute tuning, optimization, or corrective actions
Conduct on-site system verification, acceptance testing, and operational turnover
Maintain configuration baselines, redlines, and technical documentation in the Configuration Management Knowledge Base
Write and update technical documentation, briefings, drawings, and delivery artifacts
Coordinate with logistics and supply chain teams to track parts, validate spares, and support sustainment activities
Communicate technical status, risks, and limitations clearly to engineers, operators, and leadership
Support exercises and operational surges that may require evenings, weekends, or rapid reprioritization
This is not a desk-only role. Engineers in this position are expected to be comfortable working in operational spaces and at remote sites with limited reach-back
