Mechanical Engineer
Powering progress by designing, building, and testing mechanical systems.
What is a Mechanical Engineer?
Mechanical engineers design, develop, and test mechanical devices and systems, including engines, machines, tools, and heating/cooling systems. They apply principles of mechanics, thermodynamics, and materials science to solve engineering problems. They may work in a variety of industries, from automotive and aerospace to manufacturing and energy.
A mechanical engineer spends time reading blueprints and schematics, drafting specifications, and analyzing customer proposals to evaluate feasibility, cost, and maintenance. Typical days mix desktop work—calculations, computer reports, and design reviews—with meetings to confer with engineers and technicians. You investigate equipment failures, recommend remedial actions or design modifications, and direct component selection to meet performance and regulatory requirements.
