What Is A Mechanical Engineer?

A mechanical engineer is someone who designs, builds, and tests mechanical devices such as tools, engines, and machines. They often work in manufacturing plants or industrial settings.


A candidate for a mechanical engineering position should have at least a bachelor’s degree in mechanical engineering from an accredited school. They should also have strong mathematical and critical thinking skills.

Day in the Life of a Mechanical Engineer

A typical day in the life of a mechanical engineer may include working with other engineers to design a new product, conducting tests on prototypes, analyzing data from those tests, and revising the design, as necessary. They may also be responsible for supervising the production of the final product.

Duties and Responsibilities

A mechanical engineer has a wide range of responsibilities. These include:

  • Designing mechanical systems.
  • Testing mechanical prototypes.
  • Analyzing data from tests.
  • Improving upon existing designs.
  • Presenting findings to clients or management.
  • Supervising the production of products.
  • Drafting reports and technical manuals.
