Top engineering companies employ engineers and engineering consultants from multiple areas to offer a complete service to their clients. Here are the areas of engineering that are generally considered to be the main branches:

Chemical engineering is the application of chemical, physical and biological processes to convert materials or chemicals into useful products. This includes manufacturing materials plastic and steel, as well as optimising chemical processes.
Civil engineering comprises of designing, constructing and maintaining physical and naturally built structures. This involves working with the environment, transport, mines, water and buildings.
Electrical engineering deals with optimising electrictronics and using electromagnetism. Some electrical engineers design complex power systems, while others design tiny processors.
Mechanical engineering is involved with operating mechanical systems more efficiently. Think factories, vehicles and energy plants.

There are many more specialisations in engineering ranging from biomedical, aerospace, marine and genetic engineering. Engineers work across all industries to make things around us work.
