• Design, integrate, and test RF front end design & subsystems supporting EMSO and EW sensing, including antennas, RF front-end components, and software-defined radios (SDRs). • Develop RF architectures that enable wideband spectrum awareness, direction finding, and spectrum agility across VHF, UHF, and lower SHF bands. • Work with external vendors and partners to specify, evaluate, and validate custom RF components or subsystems when required to ensure Forterra’s systems can support a wide array for tasks. • Rapidly prototype RF systems using commercial off-the-shelf (COTS) or government off-the-shelf (GOTS) components, balancing speed, performance, and system maturity. • Perform RF field testing, system demonstrations, experimentation, and validation. • Collaborate with electrical and mechanical engineers to integrate RF hardware into autonomous vehicle platforms, considering antenna placement, grounding, shielding, and enclosure considerations. • Diagnose and resolve RF performance issues including interference, data rate/bandwidth limitations, and RF chain degradation in real-world environments.
