Many mechanical engineers go on to enter master's or doctoral programs, which, in addition to continued classroom study, include such activities as laboratory research and computational analysis. Most companies hiring mechanical engineers expect candidates to have bachelor's degrees in mechanical engineering. Today more and more companies are requiring employees to pursue advanced degrees, particularly if the employee manages, research, design and development projects. For those supervising an entire department, a combination of degrees and courses in engineering, accounting and business is recommended. Those who teach usually have doctorates.
Mechanical engineers work in industry, consulting practices, universities and government research.
The vast majority are employed in industry at equipment manufacturers, aerospace companies, utilities, material processing plants, transportation companies, petroleum companies and a host of other large and small firms. Job functions and responsibilities range from basic research and systems design to power plant operations and quality control. Some mechanical engineers cross over into corporate sales and management positions that require scientific and technical skills and expertise. The consulting side of the business offers mechanical engineers career opportunities in large and small engineering service firms and in private practice. Some engineers start a consulting practice later in life, often following long careers with a corporation.
