As a production plant engineer, you work in a manufacturing facility to ensure that daily operations run smoothly, with a focus on the equipment and machinery. Your responsibilities include designing new systems or equipment, directing plant personnel in proper methods and procedures of these systems and equipment, and executing or overseeing preventive maintenance and repair. Additional job duties may involve planning and supervising engineering projects, designing manufacturing equipment layouts, and checking for safety and environmental compliance. The main qualification for a career in plant engineering is a bachelor’s degree in industrial design or a sub-specialty of engineering, such as chemical, mechanical, nuclear, or electrical engineering. Professional certification, like the certified plant engineer (CPE) designation from the Association for Facilities Engineering (AFE) prove your skills, and employers may prefer these qualifications.
