3+ years of total experience in one or a combination of the following: professional experience designing, testing, and analyzing electric propulsion systems; or related spacecraft propulsion, fluid, pressure, plasma, or thruster-adjacent hardware experience (e.g., thermal, structural, power, or diagnostics for EP/plasma systems). Working knowledge of structural design, materials properties, thermodynamics, fluid/pressure/vacuum systems, and numerical analysis programming (e.g., Python, MATLAB); plasma physics as applicable (depth in several of these areas is valued; mastery of all is not expected).
