What does a mechanical systems engineer do?

A Mechanical Systems Engineer designs, analyzes, and maintains mechanical systems and components, such as engines, HVAC systems, or manufacturing equipment. They ensure that systems perform efficiently, safely, and reliably by applying principles of mechanics, thermodynamics, and materials science. Their work often involves creating technical drawings, conducting simulations, selecting materials, and collaborating with other engineers and stakeholders. Mechanical Systems Engineers play a key role in troubleshooting issues, improving existing designs, and overseeing the installation and testing of mechanical systems.
