As a prosthetics engineer, your responsibilities are to research, design, and develop prosthetics, such as artificial limbs. Your duties include coming up with new designs, improving existing devices, sketching them in design software, and working with product designers and manufacturers to address production issues. Often, you consult with physicians and other clinicians about their needs and their patients’ needs. You also interact with prosthetic wearers who help you by providing feedback about your designs or test out new prosthetics before they launch.
