Is it better to be a product manager or a maintenance engineer in the medical industry?

Hello, product manager. The product manager is responsible for drafting the product quality management system of the enterprise, guiding and supervising the implementation of the system, exercising supervision and management in product procurement, acceptance, storage and maintenance, medical device transportation and other links, and exercising veto power over the quality of medical devices. Maintenance engineers are blue-collar and skilled workers, commonly known as part-time workers, who work hard every day, and their wages are not as high as those of product managers.
