RF Engineer ..

Location: Boulder, Colorado (Onsite)

Employment Type: Contract

Role Overview: We are seeking a Level 3 RF Engineer to support the design, integration, and testing of advanced RF systems within ground-based and space-related programs. This role focuses on developing and sustaining RF hardware solutions that enable mission-critical communications and sensor capabilities. The ideal candidate will bring hands-on experience with RF equipment and signal flow, combined with a strong understanding of RF performance metrics and measurement techniques.

Key Responsibilities: Design, develop, and support RF systems and subsystems, including front-end and back-end signal chains. Analyze and troubleshoot RF signal flow across complex systems, ensuring optimal performance and reliability. Work with RF components such as upconverters/downconverters, modems, waveguides, Low Noise Amplifiers (LNAs), high-power amplifiers (HPAs), and RF antenna subsystems. Support system integration activities involving RF ground systems and communications infrastructure. Perform RF testing, validation, and performance characterization using industry-standard tools and methodologies. Evaluate system performance using key RF metrics such as Gain-to-noise temperature ratio (G/T), power levels (dBm), and antenna measurements. Collaborate with multidisciplinary engineering teams to ensure end-to-end RF performance. Participate in system design reviews, requirements development, and verification activities.

Education: Bachelor's degree in Electrical Engineering, RF Engineering, or a related technical field.

Experience: 3–7 years of experience working with RF systems or equipment. This includes hands-on experience with RF signal chain design, integration, or troubleshooting.

Technical Skills: Experience with RF test equipment (spectrum analyzers, signal generators, network analyzers). Familiarity with Ku-band and S-band RF systems. Understanding of RF propagation, link budgets, and system-level performance. Strong knowledge of RF signal flow and system architecture. Ability to interpret and analyze RF measurements (G/T, dBm, antenna patterns).

Security Clearance: Candidates must be able to obtain and maintain a Department of Defense Secret clearance as a condition of employment.

Preferred Qualifications: Experience supporting space, satellite, or ground station RF systems. Familiarity with antenna design, waveguide systems, and high-frequency RF transmission. Experience with modeling or simulation tools for RF systems.
