There are different types of engineering jobs available in the global market. Most of it, require a person who have some creative skills, along with mathematical and scientific expertise. These types of engineers are broadly classified into electrical, mechanical, civil and chemical engineer. Along with it, there are various other subcategories also. In all of these mentioned fields, people need to try for designing and building things to solve problems and hopefully turn society better. They just do this things by just keeping in mind how feasible their design will be to develop and if it is worth the cost.
A mechanical engineer is one who has been trained to design mechanical systems, and practices designing mechanical systems.
They may perform work power systems, vacuum technology, weapon systems, transportation products, aircraft, kinematic chains, or any other physical machine.
On the other hand, a electric engineer works on rather large number of electric items and systems. This includes telecommunications, fiber optics, electronic circuits, computers, electronic devices, generators, and many others.
If somebody like to go in civil engineering field they will likely to construct and design structures the public uses on daily basis. They also perform work on structures which is used by private individuals. These job description may include big buildings, roads, bridges, rail-roads, water supply, water treatment systems and certain other structures we all use on our daily basis. A chemical engineer works with chemical processing, usually on big scale. They may develop new and pioneer typo of fuel, which are hopeful better and less polluting than what people are using in current situation.
All of these mentioned engineering jobs may need huge amount of education. How much amount will be depend on the field and subcategory one chooses. A new booming sector is dealing with software field and known as software engineering.
