Work in this occupation is typically performed in a structured environment, such as an office, or an inside work environment where the temperature or humidity may be considerably different than normal room conditions.

Career paths and resources

Career paths

There is considerable mobility between mechanical engineering specializations at the less senior levels. Also, mechanical engineers work closely with civil, electrical, aerospace, chemical, industrial and other engineers, and mobility is possible between some fields of specialization in these disciplines. Finally, engineers often work in a multidisciplinary environment and acquire knowledge and skills through work experience that may allow them to practise in associated areas of science, engineering, sales, marketing or management.
