Professional Engineers typically hold a PE license, enabling them to sign off on projects and work independently, often in consulting or regulatory roles. Mechanical Engineers usually have a bachelor's degree and may or may not be licensed; they work primarily in design, analysis, and manufacturing. Salaries for PEs tend to be higher due to licensure and increased responsibilities, but both roles are vital in engineering industries.
