Chemical engineers held about 26,900 jobs in 2021. The largest employers of chemical engineers were as follows:
| Research and development in the physical, engineering, and life sciences | 11% |
| Engineering services | 11 |
| Pharmaceutical and medicine manufacturing | 5 |
| Wholesale trade | 4 |
| Petroleum and coal products manufacturing | 3 |
Chemical engineers work mostly in offices or laboratories. They may spend time at industrial plants, refineries, and other locations, where they monitor or direct operations or solve onsite problems. Chemical engineers must be able to work with those who design other systems and with the technicians and mechanics who put the designs into practice.
Some engineers travel extensively to plants or worksites, both domestically and abroad.
Injuries and Illnesses
Chemical engineers can be exposed to health or safety hazards when handling certain chemicals and plant equipment, but such exposure can be avoided if proper procedures are followed.
Work Schedules
Nearly all chemical engineers work full time. Occasionally, they may have to work additional hours to meet production targets and design standards or to troubleshoot problems with manufacturing processes. Some chemical engineers work more than 40 hours per week.
Chemical engineers typically need a bachelor’s degree in chemical engineering or a related field. Some employers prefer to hire candidates who have practical experience, so internships and cooperative engineering programs may be helpful.
Education
High school students interested in studying chemical engineering should take science classes, such as chemistry, physics, and biology. They also should take math courses, including algebra, trigonometry, and calculus.
College students typically study chemical engineering or a related field that leads to a bachelor's degree. Programs in chemical engineering usually take 4 years and include classroom, laboratory, and field studies. Some colleges and universities have 5-year engineering programs that lead to both a bachelor’s degree and a master’s degree. A graduate degree, which may include a degree up to the Ph.D. level, allows an engineer to work in research and development or as a postsecondary teacher.
Some colleges and universities offer internships and/or cooperative programs in partnership with industry. In these programs, students gain practical experience while completing their education.
ABET accredits engineering programs. ABET-accredited programs in chemical engineering include courses in chemistry, physics, and biology. These programs also include applying the sciences to the design, analysis, and control of chemical, physical, and biological processes.
Licenses, Certifications, and Registrations
Licensure for chemical engineers is not as common as it is for other engineering occupations, nor is it required for entry-level positions. 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 (PE).
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 engineers to take continuing education to keep their licenses.
Advancement
Entry-level engineers usually work under the supervision of experienced engineers. In large companies, new engineers also may receive formal training in classrooms or seminars. As junior engineers gain knowledge and experience, they move to more difficult projects with greater independence to develop designs, solve problems, and make decisions.
Eventually, chemical engineers may advance to supervise a team of engineers and technicians. Some may become architectural and engineering managers. Preparing for management positions usually requires working under the guidance of a more experienced chemical engineer.
An engineering background enables chemical engineers to discuss a product’s technical aspects and assist in product planning and use. For more information, see the profile on sales engineers.
Chemical engineers typically have an interest in the Building and Thinking interest areas, according to the Holland Code framework. The Building interest area indicates a focus on working with tools and machines, and making or fixing practical things. The Thinking interest area indicates a focus on researching, investigating, and increasing the understanding of natural laws.
If you are not sure whether you have a Building or Thinking interest which might fit with a career as a chemical engineer, you can take a career test to measure your interests.
Chemical engineers should also possess the following specific qualities:
Analytical skills. Chemical engineers must be able to figure out why a particular design does not work as planned. They must be able to ask the right questions and then find answers that work.
Creativity. Chemical engineers must be able to explore new ways of applying engineering principles. They work to invent new materials, advanced manufacturing techniques, and new applications in chemical and biomedical engineering.
Ingenuity. Chemical engineers learn the broad concepts of chemical engineering, but their work requires them to apply those concepts to specific production problems.
Interpersonal skills. Chemical engineers must develop good working relationships with people in production because their role is to put scientific principles into practice in manufacturing industries.
Math skills. Chemical engineers use the principals of calculus and other advanced topics in mathematics for analysis, design, and troubleshooting in their work.
Problem-solving skills. In designing equipment and processes for manufacturing, these engineers strive to solve several problems at once, including such issues as workers’ safety and problems related to manufacturing and environmental protection. They must also be able to anticipate and identify problems to prevent losses for their employers, safeguard workers’ health, and prevent environmental damage.
The median annual wage for chemical engineers was $105,550 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 $62,730, and the highest 10 percent earned more than $187,430.
In May 2021, the median annual wages for chemical engineers in the top industries in which they worked were as follows:
| Engineering services | $152,430 |
| Petroleum and coal products manufacturing | 126,780 |
| Research and development in the physical, engineering, and life sciences | 102,390 |
| Wholesale trade | 100,290 |
| Pharmaceutical and medicine manufacturing | 96,220 |
A 2015 survey report by the American Institute of Chemical Engineers indicated that the median yearly salary of those with no supervisory responsibility was $106,300.
Nearly all chemical engineers work full time. Occasionally, they may have to work additional hours to meet production targets and design standards or to troubleshoot problems with manufacturing processes. Some chemical engineers work more than 40 hours per week.
Employment of chemical engineers is projected to grow 14 percent from 2021 to 2031, much faster than the average for all occupations.
About 2,000 openings for chemical 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
Demand for chemical engineers’ services depends largely on demand for the products of various manufacturing industries. Many chemical engineers work in manufacturing firms that provide products to other firms. For example, environmental and sustainability concerns have led chemistry and manufacturing firms to research alternative fertilizers, resulting in a need for chemical engineers.
In addition, chemical engineering will continue to migrate into other fields, such as nanotechnology, alternative energies, and biotechnology, and thereby help to sustain demand for engineering services in many manufacturing industries. However, because it is a small occupation, the fast growth will result in only about 3,700 new jobs over the projections decade.
