The master mechanic is a highly advanced mechanic at an auto repair shop or dealership. While a master mechanic is not necessarily a higher ranking employee as compared to a mechanic, your qualifications may grant you seniority. As a master mechanic, your responsibilities revolve around fixing engine and frame failures in customer’s cars. Your day-to-day job duties involve diagnosing issues, assessing vehicle damage, and executing repairs. You may also be responsible for performing basic maintenance, but you may delegate these procedures to less advanced employees. Master mechanics must be knowledgeable in technology, engine repair, collision repair, and other areas. As a master mechanic, you may work for yourself, an automobile dealer, or a larger auto repair shop.
