The Opportunity:
The Opportunity:
CACI is seeking a Senior RF and Antenna Systems Engineer to support the design, development, integration, and test of advanced RF and antenna solutions for mission-critical defense applications. This role focuses on phased array antennas, reflector antenna systems, beamforming architectures, and RF subsystem integration across the full engineering lifecycle-from concept development and requirements definition through prototype development, test, and transition to fielded systems.
You will work in a collaborative environment with multidisciplinary engineering teams to deliver innovative, practical solutions for complex technical challenges.
Responsibilities:
  • Lead and support the design, development, integration, and test of advanced RF, phased array, and reflector antenna systems.
  • Develop system and subsystem architectures, requirements, and trade studies for antennas, apertures, beamforming approaches, RF distribution networks, feeds, and associated hardware.
  • Perform system-level analyses including RF propagation, link budgets, range estimates, cascade analysis, interference assessments, and sensitivity evaluations.
  • Support prototype development, fabrication, and assembly of RF systems and antenna hardware.
  • Develop and execute test plans and procedures for laboratory, chamber, range, and field testing; analyze results and recommend design improvements.
  • Present technical concepts, tradeoffs, and program status to leadership, customers, and stakeholders.
  • Contribute to proposals, IRAD efforts, technical volumes, and BOE development.
  • Collaborate across multidisciplinary teams and provide technical guidance to junior engineers as needed.

Qualifications:
Required:
  • Bachelor's degree in Electrical Engineering, Computer Engineering, Physics, or a related technical field.
  • 10+ years of experience in RF systems, antenna systems, or related mission applications.
  • Experience designing, analyzing, integrating, and testing RF and antenna systems, with emphasis on phased arrays and/or reflector antennas.
  • Strong knowledge of RF propagation, link budgets, range estimates, cascade analysis, interference effects, and system sensitivity.
  • Experience developing and managing system and subsystem technical requirements.
  • Hands-on experience with RF test equipment such as network analyzers, spectrum analyzers, and power meters.
  • Familiarity with antenna performance metrics such as gain, beamwidth, sidelobes, efficiency, scan loss, and aperture illumination.
  • Experience working in multidisciplinary engineering teams.
  • Strong written and verbal communication skills.
  • Experience supporting proposals and BOE development.
  • Ability to work independently in a fast-paced environment.

Desired:
  • Master's degree or higher in Electrical Engineering, Electromagnetics, RF/Microwave Engineering, or a related field.
  • Experience with AESA, digital or hybrid beamforming, array calibration, and beam steering validation.
  • Experience with reflector antenna systems, including feed design, aperture illumination, alignment, and efficiency optimization.
  • Experience with tools such as Microwave Office, Keysight Genesys, MATLAB, and/or Python.
  • Understanding of spherical- and planar near-field antenna ranges and near-field to far-field transformation methods.
  • Familiarity with electromagnetic modeling, antenna simulation, and RF analysis tools.
  • Experience supporting defense, intelligence, or other government mission customers.
  • Active TS/SCI clearance.
