What Does a Process Engineer Do?

Process engineers are responsible for designing and improving industrial processes in order to maximize efficiency and productivity while minimizing waste and costs. Among the industries in which they work are manufacturing, chemicals, pharmaceuticals, and energy. Their responsibilities include analyzing existing processes, identifying areas for improvement, and designing and implementing new processes to satisfy operational needs. In order to ensure quality standards are met, and the process is operating as intended, they work closely with other engineers and technicians.

A process engineer must have engineering principles and a strong understanding of equipment and systems. Their problem-solving and analytical skills must be excellent, and they should be capable of rapidly identifying and resolving technical issues. To work effectively with other engineers, technicians, and stakeholders, they must also possess strong communication and interpersonal skills. Typically, process engineers are required to have a bachelor’s degree in chemical engineering, industrial engineering, or a related field. Depending on their industry, they may also need to undergo additional training or certification. Process engineers are often trained on the job and gain experience before moving into engineering roles.

How to Hire a Process Engineer

Consider the following when hiring a process engineer:

  • Recruiting: Do you have the internal resources and tools to source and recruit for this role successfully?

  • Duration: Is this a one-time project, or an indefinite need?
  • Management: Can you effectively direct the work effort?
  • Urgency: Are there any deadlines associated with this need?
  • 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, various great options exist for every scenario, no matter how unique. When hiring a process engineer, we recommend the following options:
