What Does a Mechanical Engineer Do (Roles and Responsibilities)?

A mechanical engineer designs and develops various machines that could be dealing with the manufacturing of heavy parts or even small but sensitive pieces of instruments. Mechanical engineering deals with the complete process of the production of instruments. Some examples of products that need a mechanical engineer’s expertise are printers, disk drives, prosthetic devices, semiconductor tools, robots and heavy machineries like turbines, engines and transformers.

Mechanical engineering is one of the oldest disciplines in engineering, and the areas where it is involved in a major way are mechatronics and nanotechnology. Other industries that influences on mechanical engineering include metallurgical engineering, civil engineering, aerospace engineering and electrical engineering.

In this blog, we will explore the role of a mechanical engineer, the responsibilities that come with the profile and the career prospects.

What is the Role of Mechanical Engineer?

The role of a mechanical engineer can be broken down into the following:

  • Analyse the problem to find out how a machine can solve the problem

  • Design or redesign devices

  • Develop and test prototypes
