Senior RF Engineer

Senior Radio Frequency Engineer

A rapidly growing research and development organization specializing in advanced antenna technologies for Department of Defense and Commercial/Civil Space applications. Core business focus areas include tactical radar systems, satellite communications, millimeter-wave antennas, and large space-deployable antenna structures.

The team possesses extensive expertise in both small and large phased-array radar systems, satellite communication phased arrays, and deployable space antennas. The facility includes a state-of-the-art 20' × 30' robotic near-field antenna range, enabling highly versatile testing of antennas, radomes, and radar cross-section measurements through automated robotic methods.

The organization is seeking an experienced Senior Radio Frequency Engineer to lead innovative active electronically steered antenna (AESA) development programs. This role provides technical ownership of RF system design, simulation, integration, and testing.

Key Responsibilities

• Perform full-wave electromagnetic modeling and simulation using CST or similar tools
• Design and test active RF networks
• Select and integrate active components such as amplifiers, switches, and phase shifters into PCB assemblies
• Conduct Vector Network Analyzer (VNA) calibration, measurement, and data evaluation
• Execute antenna testing and post-processing using far-field and near-field methods
• Prepare detailed technical reports, analysis summaries, and presentations
• Design multilayer RF PCB transitions and support overall PCB layout considerations
• Perform system-level analysis and testing for radar and communication systems
• Provide technical leadership and mentorship to supporting design and test engineering personnel

Qualifications

• Bachelor of Science in Electrical Engineering (Master's degree preferred)
• Deep familiarity with small and large antenna array radiator design and analysis
• Proficient in full-wave electromagnetic simulation
• Experience with MATLAB, Python, or C for modeling and data analysis
• Knowledge of PCB layout for RF and mixed-signal designs
• Self-starter with strong collaboration skills and the ability to work effectively in a team environment
• Ten or more years of relevant RF engineering experience
• Must be a U.S. citizen

This is a full-time, on-site position located in Berthoud, Colorado.
