What Does an Engineer Do? General Information

An engineer is a professional who applies scientific knowledge to the design, construction, and operation of structures, machines, or systems. Engineers are involved in all aspects of a project, from initial feasibility studies and concept designs to overseeing construction and commissioning.

The work of an engineer can be divided into three main categories. What does an engineer do when it comes to design, construction and operation?


Engineers design things. This can be anything from the skeleton of a skyscraper to the circuit board of a cell phone. The key here is that engineers use their scientific knowledge to figure out how something should be made or how it should work. This step usually requires lots of creativity and problem-solving.


Once the design is finished, it’s time to start building. Engineers oversee the construction of their designs to make sure everything is being built according to plan. This step usually requires a lot of coordination and communication with other professionals, such as architects, contractors, and subcontractors.


Once a project is completed, engineers may be responsible for its operation. This could involve anything from ensuring that a power plant is running smoothly to making sure that an elevator is working properly. Engineers often use their scientific knowledge to figure out how to improve the performance of their designs.
