Engineers are responsible for the innovation and development of new products, services, technologies and processes. They can work in many different fields, making this a diverse career for prospective engineers to explore. Understanding the scope of engineering can help you decide if engineering is a good fit for your interests and skills. In this article, we explore what engineering is and some careers you can find in this field.

What is an engineer?

An engineer is a professional who is involved in inventing, designing and maintaining a variety of machines, structures and data systems. Engineers are also responsible for adhering to their employer's specifications for budget and timeline. Engineers are experts in their fields, creating and innovating constantly.

What does an engineer do?

Engineers use math and science to solve problems and make use of new discoveries. While engineers don't typically make scientific discoveries themselves, they take the information from these and find practical uses for them. They pursue valuable innovations that advance the way humans use products or perform tasks. Engineers can work with everything from massive architectural constructions to complex maps of the human genome.

Average salary for engineers

The average salary for an engineer is $85,720 per year. However, this varies by industry, with industrial engineers making an average of $73,922 and aeronautical engineers earning an average salary of $98,310. Experience impacts an engineer's salary as well. Those with a longer tenure and more proven abilities typically earn more.

Skills for engineers

Several key skills are important for engineers. These equip them to come up with the innovations that will help them succeed and advance in their careers.

  • Creativity: Engineers must have creative minds that help them come up with new constructs and original approaches.

  • Communication: Engineers are responsible for communicating their ideas clearly with others on their team. They may do so orally or in writing.

  • Attention to detail: The small details can make a big difference in engineering. These professionals must have a keen eye for even the smallest elements of a project.

  • Self-discipline: Engineering is a challenging career that continuously presents new problems to solve. Engineers must have the self-discipline to work diligently on each project until it is complete.

  • Technical skills: The scope of an engineer's technical and scientific abilities varies by specialty, but all engineers should have strong technical skills.

How to become an engineer

A strong educational background is necessary to become an engineer. Follow these steps to begin your engineering career:

  1. Get a bachelor's degree.

  2. Complete the Fundamentals of Engineering exam.

  3. Gain entry-level work experience.

  4. Complete the state licensure examination.

  5. Prepare your resume.

1. Get a bachelor's degree

Engineers must have a minimum of a bachelor's degree, preferably in engineering or engineering technology. Most programs allow for specialization, which will help you gain detailed knowledge in a particular area of engineering. Look for an educational program that's accredited by the Accreditation Board for Engineering and Technology.

2. Complete the Fundamentals of Engineering exam

The FE exam is the first of two tests required to gain licensure as a professional engineer. In most states, you can take this test upon graduation. After passing the test, you become known as an engineer in training or an engineer intern.

3. Gain entry-level work experience

Engineers need a minimum of four years of relevant work experience to gain licensure in most states. Seek an entry-level engineering position or internship that will help you hone your skills, improve your engineering skills and prepare for licensure.

4. Complete the state licensure examination

The exact requirements for licensure as an engineer vary by state, but typically include an examination after you've completed the necessary work experience. Complete your state's exam and any other requirements to become a professional engineer.

5. Prepare your resume

Draft a detailed resume that provides specific examples of your engineering experience. Detail the solutions and systems that you've designed as well as their benefits. For example, if your manufacturing processes increase output by 30%, you should include this valuable statistic. Include your relevant skills as well, such as communication, project management and problem-solving.
