Principal RF Engineer

Your Impact We are seeking a Principal RF Engineer with advanced expertise in RF front-end systems and antenna design to spear-head the development of high-performance Software Defined Radio (SDR) platforms.

You will be instrumental in architecting and implementing RF front ends, with an emphasis on high-power amplifiers (>50dBm), LNAs, and antennas capable of operating across broad and dynamic frequency ranges.

This role demands both technical leadership and hands-on design excellence, supporting next-generation RF systems critical to our airspace security solutions.

What You'll Do Location: Onsite in Sterling, Virginia * Architect and develop RF front ends including PAs, LNAs, and filters.

* Specify and integrate antennas for SDR platforms, ensuring optimized performance across frequency bands and dynamic environments.

* Lead RF validation, characterization, and environmental qualification for field deployments.

* Collaborate with other RF engineers, antenna experts, hardware, software, and systems teams to optimize performance in real-world scenarios.

* Serve as a technical leader and mentor, supporting the long-term roadmap and cross-functional integration What You Bring * M.S.

in Electrical Engineering, Physics, or a related field (Ph.D.

preferred). * 8+ years of experience in advanced RF system development, particularly in SDR, wireless, or sensing domains.

* Demonstrated expertise in: * Proficient in RF simulation and test tools (ADS, HFSS, CST, MATLAB/Python, VNA, spectrum analyzer, etc.). * Deep understanding of propagation physics, impedance matching, linearity, and thermal effects in RF systems.

* Experience with counter-UAS, radar, SIGINT, or defense-oriented RF systems.

* Familiarity with SDR platforms such as USRP, GNURadio, or custom FPGA-based solutions.

* Experience with beamforming, MIMO, direction-finding, or geolocation technologies.

* Proven record of patents, publications, or fielded RF systems.
