What is a Chemical Engineer?

The chemical engineers apply several scientific and mathematical disciplines as they develop new, more cost-effective ways to use both materials and energy to make life easier and safer for people.

Chemical engineers are responsible for creating new materials such as solvents, anti-bacterial polymers, coatings, pesticides, fuel, and other complex chemical components used in manufacturing, food production, etc. Chemical engineers work in several industries: electronic, pharmaceutical, biomedical, consumer products, food, petroleum, chemical, environmental industries, and materials.

Steps to Becoming a Chemical Engineer

  • Step 1: Find a College Program

  • Step 2: Earn Your Degree in Chemical Engineering

  • Step 3: Internship

  • Step 4: Apply for, Take, and Pass Examination


Step 1: Find a College Program

Check out all of the chemical engineering programs within the universities in which you are most interested. Read the descriptions of each program, to include what you will learn and what you’ll be expected to do.

You should also know about the strong points of the different programs you’re considering. Each program will strengths in different areas; one school may have an excellent record of educating chemical engineers who are ready to work in the industry, compared to another university that has excellent faculty that are well known and have a lot of experience in the field.

Find Your Online Chemical Engineering Program

Explore the areas of focus of each chemical engineering program, which will also vary from one school to another. Look for classes and research areas like Biofilm engineering and muscle systems. Once you’re satisfied with your choice of school, you’re ready to apply to 1-3 programs and wait for your admission letter.

Step 2: Earn Your Degree in Chemical Engineering

Engineering programs are notorious for being difficult. You’ll need to approach all your classes with a strong work ethic. You’ll also learn to work independently and as a part of a student group. You’ll do the same when work in chemical engineering, working with a lab full of technicians who are all working on the same problem. Do your group work, complete your part of every project and contribute everything that’s expected of you.

Make sure that you attend an Accreditation Board for Engineering and Technology (ABET) accredited program. This is vitally important, as it may be required for licensure in your state. This accreditation proves to future educators and employers that your education was top-quality and that it was rigorous enough to teach you everything you needed to know. Non-accredited programs are unsupervised and unproven and should be avoided when you’re going for any engineering position. At the end of it all, you’ll have earned the degree in chemical engineering that will land you the first job in the first step of your career.

Step 3: Internship

Pursue a good internship. This is a way of gaining highly valuable work experience, which you can put on your resume. Future employers will look for internship experiences because they see work experience as something that is an imperative in your field.

Before you get into an internship, polish up your resume, including anything that would showcase your leadership abilities and your knowledge of engineering. Visit the Career Placement Center on your campus. An internship experience is so important that future employers will almost always choose recruits who have that experience documented on their resumes over those who don’t.

Step 4: Apply for, Take, and Pass Examination

Before your graduation ceremony, start the process of signing up for your chemical engineering licensing exam. If you plan to work in this industry, then licensure makes you even more attractive and will likely be necessary for most jobs. You’ll be taking the Fundamentals of Engineering (FE) exam in order to obtain licensure. You should also do your own research for any other requirements in your state, as this type of licensure is not national, but state-based.

To prepare for your licensure exams, make sure you complete a minimum of four years of acceptable engineering practice. You should also take and pass the Principles and Practice of Engineering exam.

What Do Chemical Engineers Do?

In your workdays, you’ll work on creating or improving chemical products or materials. However, this can be used in nearly any industry; in manufacturing you could create lubricants for machines, in healthcare you can create polymers which have antibacterial properties to make hospitals safer, you can create chemicals which break down plastics safely or more efficient energy storage if you want to work in environmental science. No matter what industry you are interested in, there may very well be chemical engineering involved.

You could be expected to work in the petrochemical industry, in a fertilizer plant, or, a personal care product manufacturer. You could be tasked with developing a new fingerprinting method using a person’s sweat pores - this is being worked on. Or, you may study prickly pears, learning about their properties as you and your team look for ways to purify drinking water.

Skills for Chemical Engineers to Acquire

When you work in chemical engineering, you will be expected to have and use a wide range of skills. Your work is highly technical, requiring the following skills:

  • Mathematical
  • Engineering
  • Physics
  • Highly Versatile, able to switch between engineering disciplines
  • Basic and Advanced Chemistry
  • Excel
  • ChemDraw
  • Mathematica
  • LoggerPro
  • Laboratory Techniques
  • Analytical
  • Good attention to detail
  • Ability to summarize well
  • Data Analysis
  • Test Hypotheses
  • Evaluate Results
  • Clarify Problems
  • Develop Theories
  • Able to identify relationships between problems and solutions
  • Use analogy to reason
  • Apply logic to engineering problems
  • Able to spot patterns and structures
  • Excellent problem-solving skills
  • Able to analyze how things work together
  • Use reasoning and logic to solve various problems
  • Enjoy chemistry and math
  • Able to work within safety standards

All of these skills are vital to the work that chemical engineers do every day. Because you will be working with chemicals and various processes to make new products, you’ll be exposing yourself and others to some risks, and this is why you need to know, respect, and work within strict standards of safety.

Alternative Paths

If you plan to work in the chemical engineering field, you won’t be able to enter this field without extensive education in chemical engineering. In addition, several internships are vital for you so you can begin to apply theory to practice.

Several universities work to provide experience-based learning for their engineering students in every engineering discipline. These include paid and unpaid work assignments and internships that are structured specifically to meet the needs, abilities, and interests of students in the chemical engineering major. These work experiences also meet the needs of employers who offer internships to these students.

One student noted the difficulty in transitioning from a college major to a full-time job without the needed experience—in any engineering discipline, this is especially true.

Find Online Chemical Engineering Schools

Other colleges point out that people who want to become chemical engineers “need” strong foundations in chemistry, physics, biology and mathematics. Without the foundational grounding that these courses provide, anyone who tries to work in a chemical engineering position will soon become lost and flounder in their daily work.

The undergraduate years are the most critical. This is when you have the best opportunity to take the widest array of classes outside the chemical engineering discipline, including accounting or policy classes as well as a different engineering disciplines.
