What does a mechanical prototype engineer do?

A Mechanical Prototype Engineer designs, builds, and tests physical prototypes of mechanical systems or products. They work closely with design teams to turn conceptual ideas into working models, often using CAD software, 3D printing, machining, and other fabrication techniques. Their role is essential for identifying design flaws, evaluating functionality, and making improvements before full-scale production. They also document their processes and collaborate across engineering, manufacturing, and quality assurance departments to ensure the final product meets specifications.
