What Does a Chemical Engineer Do?

A chemical engineer designs and troubleshoots processes for making fuels, foods, pharmaceuticals, chemicals, and biologicals. They take a process developed in a laboratory setting and turn it into a practical application. Chemical engineers are employed by companies in various industries, from biomedical to aerospace, automotive, energy, and the military.

Chemical engineers are involved in the development and production of almost every industrially manufactured product. They design experiments, monitor results, and conduct tests throughout production. In some cases, chemical engineers create safety procedures for working with dangerous chemicals. Usually, a chemical engineer specializes in a particular chemical process such as oxidation, or a specific field or type of product, like food additives.

  • Duration: Is this a one-time project or an ongoing need?
  • Management: Do you have the time and expertise to direct the work effectively?
  • Urgency: How soon does the work need to be completed?
  • Headcount: Do you have the budget and approval for an internal employee, or should you consider alternate options?

Answering these questions will help determine the best course of action for your current hiring need. Fortunately, great options exist for every scenario. These are our recommendations:

1. Use 4 Corner Resources (or another professional recruiting firm)
