Experience with application of GD&T to engineering drawings. Demonstrated experience applying Design for Manufacturability and Assembly principles. Ability to visually see and focus on fine details of small components. Good verbal and written technical communication skills. PREFERRED EXPERIENCE Experience building proof‑of‑concept prototypes from the ground up, using 3D printing, off‑the‑shelf parts, and rapid prototype vendors. Experience in a lean, mid‑volume manufacturing environment, including debugging design issues that arise in early pre‑production. A portfolio of creative product design solutions that optimize size, cost, functionality, or aesthetics. Experience with thermal or vibration analysis, simulation, and experimentation. Understanding of a variety of manufacturing processes used on metal, plastics, and glass. Understanding of ASTM E595 – how to choose materials for space. Familiarity with cubesator space flight hardware design techniques. Familiarity with fiber‑optic or free‑space optical systems or optical atomic clocks. Experience using SolidWorks PDM and Arena PLM or similar document control systems. Experience using SolidWorks, ANSYS, or COMSOL design analysis tools.
