1+ years of total experience in one or a combination of the following: professional or internship experience designing, testing, and analyzing power electronics, analog/mixed-signal, or spacecraft avionics; academic research with comparable design/build/test ownership of power supplies, plasma or electric-propulsion power processing, high-voltage, or control electronics; or closely related hardware experience (e.g., motor drives, converters, RF/power, or instrumentation for vacuum or plasma systems). Working knowledge of analog and power electronics, high-voltage design, circuit protection, EMI/EMC, and numerical analysis programming (e.g., Python, MATLAB); control loops, plasma or nonlinear electrical loads, schematic/layout review, vacuum operation, and C/C++ as applicable (depth in several of these areas is valued; mastery of all is not expected).
