Experience with dynamic mechanical systems (motors, actuators, mechanisms, etc.) Strong 3D modeling (CAD) skills for complex parts and assemblies. Self sufficient with at least basic structural and thermal simulation. Self sufficient with hands-on prototyping, metal fabrication, 3D printing. Competence with assembly and test fixture design.
