Chemical engineers with bachelor's degrees usually have their first job related to chemical, pharmaceutical, or biotechnology operations (Chemical Engineering Degrees and Careers | How to Become a Chemical Engineer. n.d. ). This work can be done in the field or in the office. Some young engineers work for contracting companies and may be involved in plant design, commissioning, troubleshooting, or validation (“FAQ, Chemical Engineering,” n.d.). There are many career paths you can choose once you earn a chemical engineering degree. Some fields of work for chemical engineers include: Chemical Process Industries (CPI) – Design and operation of reactors, processes, and systems to combine, transport, separate, and recycle chemicals; Biotechnology: Using living cells, cellular materials, and biological techniques to produce antibiotics, insulin, recombinant DNA, artificial organs, techniques for medical, environmental, and nutritional improvements, among other things; Food and drugs; Advanced Materials: Used in the aerospace, automotive, electronics, minerals and imaging industries to design and control the production of advanced polymers, ceramics and hybrid materials for improved performance; Environment, Health and Safety: Every process involving chemicals produces some by-products, and chemical engineers control these variables through process monitoring and control, efficient and safe process design, waste treatment, environmental impact studies, etc..;
