What Is a Mechanical Engineer?
A Mechanical Engineer is a STEM professional who designs, analyzes, tests, and builds mechanical systems and devices. As one of the most versatile engineering fields, mechanical engineers work across aviation, aerospace, automotive, energy, robotics, manufacturing, and research. In aerospace specifically, they help design aircraft structures, engines, landing gear, thermal systems, actuators, robotics, propulsion components, and ground-support equipment.
Mechanical engineers apply physics, mathematics, materials science, thermodynamics, and mechanical design principles to develop systems that must operate safely, efficiently, and reliably in demanding environments.
Their responsibilities include:
Designing mechanical components and assemblies
Creating 3D CAD models and engineering drawings
Running simulations (structural, thermal, fluid, vibration)
Conducting tests and experiments
Evaluating materials, loads, and performance limits
Troubleshooting mechanical issues and failures
Supporting manufacturing and quality assurance
Collaborating with multidisciplinary engineering teams
Mechanical engineers are employed by aerospace companies, airlines, automotive firms, energy companies, defense contractors, robotics teams, research labs, and tech companies.
