The ideal candidate has 15+ years of experience in RF systems engineering, RF signature modeling, signal processing, propagation modeling, and the development of software or simulation products that have been shipped to customers or fielded as part of an operational capability. This role will translate RF physics and customer requirements into maintainable, production-quality software that accurately represents propagation, attenuation, time delay, Doppler, waveform interaction, and the superposition of multiple RF components at a sensor or victim receiver.
