What Does An Engineer Do?

Are you considering pursuing a career in engineering?

That would indeed be the right choice.


There are numerous job opportunities within the engineering field that provide career stability.

From a switchboard to an aircraft, a light bulb to a missile, we can see how the engineering field and engineers contribute to our daily lives.

So for you to have a better insight into the engineering field, we will discuss what engineers do. We will also look at where engineers work to understand the working environment of this field.

What is an Engineer?

An engineer is responsible for planning, designing, building, and supervising projects to fulfill society’s requirements. They apply principles of science, technology, and math to solve problems. 

We can witness the magic of engineering around us and across the globe in almost everything as engineers work devotedly to improve how we travel, live, work, communicate, entertain, and stay healthy.   

Considering this. it is not uncommon for people to ask, “do engineers build things as well?”  

Well, engineers work to build things that make our lives easier.

So, what do engineers build?  

These are the things engineers build:

  • Homes
  • Buildings 
  • Bridges 
  • Roads
  • Tunnels
  • Airports
  • Dams
  • Sewerage systems 

So if you love to design and invent new things to resolve obstacles, a career in engineering may be the perfect fit for you. 

What Does an Engineer do?

While there are multiple disciplines of engineering to opt for, all engineers share some basic set of duties and responsibilities.

So, let’s take a look at what does an engineer do on a daily basis:


Planning and preparing are the core responsibilities of successful engineers. Engineers do planning by creating detailed drawings and budget plans and then executing them. In addition, they outline the project deadlines to develop and assure that the project gets completed on time and within budget.


Companies employ engineers to develop accurate and precise specifications of the project. Engineers design and carry out experiments for safety and efficiency to test their ideas, which is considered an essential step in building. 


What’s most crucial at every step of development in engineering is communication. For this reason, engineers have to make technical reports to effectively communicate their research and findings with their coworkers and customers. Furthermore, they discuss regulatory manuscripts and report safety issues. 

15 Popular Engineering Fields

Below are some of the most popular types of engineering fields that discuss the responsibilities of engineers working in respective fields:

  1. Electrical engineering

An electrical engineer is responsible for transferring electricity from an engine to a powered source such as a plane, car, or electronic device. They are also responsible for designing, developing, installing, and troubleshooting electrical appliances and products. 

  1. Chemical engineering 

A chemical engineer is responsible for planning, creating, and testing products for consumption, like food, drink, and pharmaceuticals. They convert raw materials into end products. They also devise procedures to transport, transform, and develop products.

  1. Civil engineering

A civil engineer builds construction projects for transportation through planning and designing. Those projects can be both private as well as public, which includes dams, flyovers, skyscrapers, airports, and sewerage systems. 

  1. Mechanical engineering

A mechanical engineer is responsible for designing and inventing machines that utilize or generate energy. In addition, they are also responsible for creating, fixing, installing power-generating machines such as engines, generators, medical equipment, and steam/gas turbines. Creating and troubleshooting power-consuming machines like elevators, cars, HVAC systems, and food processors is also done by civil engineers.

  1. Biological engineering

Biological engineering involves studying living organisms and processes for designing and implementing solutions. Biomedical engineers are responsible for creating and troubleshooting medical diagnostic equipment for hospitals. They also replicate parts of the body and artificial internal organs for patients that require them.

  1. Aerospace engineering

Aerospace engineers are responsible for designing, testing, and overseeing the manufacturing of spacecraft, aircraft, and missiles. They also develop new and advanced technologies used in defense systems, aviation, and space exploration. 

  1. Agricultural engineering

Agriculture engineers are responsible for designing agricultural equipment, machinery, sensors, procedures, and structures. They develop methods for conserving soil and water to improve agricultural products processing.

  1. Environmental engineering

Environmental engineers apply the principles of chemistry and biology to resolve environmental issues. They are responsible for recycling, air and water pollution control, waste disposal, and public health.

  1. Industrial engineering

Industrial engineers are responsible for figuring out how to utilize the primary factors of production, which includes people, machines, materials, information, and energy, for manufacturing a product or offering a service in the most efficient way possible. They create management control systems to help plan finance and analyze costs, coordinate activities using control systems, and design production planning. 

  1. Marine engineering

Marine engineers oversee the design, building, and maintenance of boats, ships, and relevant equipment. They are responsible for supervising the design and construction of aircraft carriers, submarines, tankers, and sailboats. Marine engineers work on ships’ systems such as steering and propulsion.

  1. Petroleum engineering

Petroleum engineers develop techniques for extracting oil and gas from deposits beneath the earth. They are also responsible for attaining the maximum oil and gas recovery by designing methods and equipment.  

  1. Nuclear engineering

Nuclear engineers research procedures, instruments, and systems that benefit from nuclear radiation and energy. They are responsible for designing, developing, monitoring, and operating nuclear plants to produce power. 

  1. Materials engineering

They are responsible for creating products by developing, processing, and testing different materials. They make everything from golf clubs, computer chips, aircraft wings to snow skis. They are also involved in choosing materials for new applications.

  1. Health and safety engineering

Health and safety engineers apply knowledge of systems engineering to ensure the protection of people and property against any harm. Moreover, they are responsible for recognizing and estimating potential hazards, like the dangers of fires or risks involved in handling toxic chemicals.  

  1. Computer engineering 

Computer engineers are involved in researching, designing, developing, testing, and supervising computer hardware production and installation, including circuit boards, computer systems, computer chips, etc.

Engineering Job Work Environment

Engineering workplace depends on:

  • Type of engineer 
  • Job description of an engineer 
  • The organization that an engineer works for

Many engineers work in a typical office environment, laboratories, factories, offshore oil rigs, or industrial plants. Some work outside in the field to supervise their projects. Other engineers, for instance, ship engineers, travel most of the time to local industrial plants or foreign worksites.

Engineers Average Salary in the USA

On average, an engineer’s salary in the United States is $49.87 per hour or $97,254 per year. 

Entry-level engineering positions start from $74,906 per year, while most experienced engineers’ salaries go up to about $140,004 per year on average. 


The engineering field has influence all over the world. We can see how engineers work to improve our way of traveling, living, and communicating by developing city structures, buildings, healthcare, etc.
