Industrial engineers held about 301,000 jobs in 2021. The largest employers of industrial engineers were as follows:
| Transportation equipment manufacturing | 16% |
| Computer and electronic product manufacturing | 12 |
| Professional, scientific, and technical services | 12 |
| Machinery manufacturing | 9 |
| Fabricated metal product manufacturing | 6 |
Depending on their tasks, industrial engineers work either in offices or in the settings they are trying to improve. For example, when observing problems, they may watch workers assembling parts in a factory. When solving problems, industrial engineers may be in an office at a computer where they analyze data that they or others have collected.
Industrial engineers must work well on teams because they need help from others to collect information about problems and to implement solutions.
Industrial engineers may need to travel to observe processes and make assessments in various work settings.
Work Schedules
Most industrial engineers work full time. Depending upon the projects in which these engineers are engaged, and the industries in which the projects are taking place, hours may vary.
Industrial engineers typically need a bachelor’s degree. Some employers prefer to hire candidates who have experience, so cooperative-education programs may be beneficial.
Education
High school students interested in industrial engineering should take classes in mathematics, such as algebra, trigonometry, and calculus; computer science; and sciences, such as chemistry and physics.
Industrial engineers typically need a bachelor's degree in industrial engineering or industrial engineering technologies. However, many industrial engineers have degrees in mechanical engineering, electrical engineering, manufacturing engineering, or general engineering.
Bachelor’s degree programs include lectures in classrooms and practice in laboratories. Courses include statistics, production systems planning, and manufacturing systems design, among others. Many colleges and universities offer cooperative education programs in which students gain practical experience while completing their education.
Several colleges and universities offer 5-year degree programs in industrial engineering that lead to a bachelor’s and master’s degree upon completion, and several more offer similar programs in mechanical engineering. A graduate degree allows an engineer to work as a professor at a college or university or to engage in research and development. Some 5-year or even 6-year cooperative education plans combine classroom study with practical work, permitting students to gain experience and to finance part of their education.
Programs in industrial engineering are accredited by ABET.
Licenses, Certifications, and Registrations
Licensure is not required for entry-level positions as an industrial engineer. A Professional Engineering (PE) license, which allows for higher levels of leadership and independence, can be acquired later in one’s career. Licensed engineers are called professional engineers (PEs). A PE can oversee the work of other engineers, sign off on projects, and provide services directly to the public. State licensure generally requires
- A degree from an ABET-accredited engineering program
- A passing score on the Fundamentals of Engineering (FE) exam
- Relevant work experience, typically at least 4 years
- A passing score on the Professional Engineering (PE) exam.
The initial FE exam can be taken after one earns a bachelor’s degree. Engineers who pass this exam are commonly called engineers in training (EITs) or engineer interns (EIs). After meeting work experience requirements, EITs and EIs can take the second exam, called the Principles and Practice of Engineering.
Each state issues its own licenses. Most states recognize licensure from other states, as long as the licensing state’s requirements meet or exceed their own licensure requirements. Several states require continuing education for engineers to keep their licenses.
The Society of Manufacturing Engineers offers certification, which requires a minimum of 8 years of a combination of education related to manufacturing and at least 4 years of work experience.
Advancement
Industrial engineers who are just starting out usually work under the supervision of experienced engineers. In large companies, new engineers also may receive formal training in classes or seminars. As beginning engineers gain knowledge and experience, they move on to more difficult projects with greater independence to develop designs, solve problems, and make decisions.
Eventually, industrial engineers may advance to become technical specialists, such as quality engineers or facility planners. In that role, they supervise a team of engineers and technicians. Earning a master’s degree facilitates such specialization and thus advancement.
Many industrial engineers move into management positions because the work they do is closely related to the work of managers. For more information, see the profile on architectural and engineering managers.
Industrial engineers typically have an interest in the Thinking, Persuading and Organizing interest areas, according to the Holland Code framework. The Thinking interest area indicates a focus on researching, investigating, and increasing the understanding of natural laws. The Persuading interest area indicates a focus on influencing, motivating, and selling to other people. The Organizing interest area indicates a focus on working with information and processes to keep things arranged in orderly systems.
If you are not sure whether you have a Thinking or Persuading or Organizing interest which might fit with a career as an industrial engineer, you can take a career test to measure your interests.
Industrial engineers should also possess the following specific qualities:
Creativity. Industrial engineers use creativity and ingenuity to design new production processes in many kinds of settings to reduce use of material resources, time, or labor while accomplishing the same goal.
Critical-thinking skills. Industrial engineers create new systems to solve problems related to waste and inefficiency. Solving these problems requires logic and reasoning to identify strengths and weaknesses of alternative solutions, conclusions, or approaches to the problems.
Listening skills. These engineers often operate in teams, but they must also solicit feedback from customers, vendors, and production staff. They must listen to customers and clients to fully grasp ideas and problems the first time.
Math skills. Industrial engineers use the principles of calculus, trigonometry, and other advanced topics in mathematics for analysis, design, and troubleshooting in their work.
Problem-solving skills. In designing facilities for manufacturing and processes for providing services, these engineers deal with several issues at once, from workers’ safety to quality assurance.
Speaking skills. Industrial engineers sometimes have to explain their instructions to production staff or technicians before they can make written instructions available. Being able to explain concepts clearly and quickly is crucial to preventing costly mistakes and loss of time.
Writing skills. Industrial engineers must create documentation for other professionals or for future reference. The documentation must be coherent and explain their thinking clearly so that others can understand the information.
The median annual wage for industrial engineers was $95,300 in May 2021. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $60,850, and the highest 10 percent earned more than $129,620.
In May 2021, the median annual wages for industrial engineers in the top industries in which they worked were as follows:
| Computer and electronic product manufacturing | $99,340 |
| Professional, scientific, and technical services | 99,340 |
| Transportation equipment manufacturing | 97,090 |
| Machinery manufacturing | 80,260 |
| Fabricated metal product manufacturing | 78,210 |
Most industrial engineers work full time. Depending upon the projects in which these engineers are engaged, and the industries in which the projects are taking place, hours may vary.
Employment of industrial engineers is projected to grow 10 percent from 2021 to 2031, faster than the average for all occupations.
About 22,400 openings for industrial engineers are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
Employment
Industrial engineers focus on reducing internal costs, making their work valuable in manufacturing and other industries, such as consulting and engineering services and research and development firms. As more companies look to lower costs, demand is expected to increase for industrial engineers to optimize production processes, manage supply chains and logistics, and provide expertise on automation.
