What is process engineering?

Process engineering is a field of engineering focused on designing, implementing, controlling, and optimizing industrial processes, particularly in manufacturing and chemical production. Process engineers work to develop efficient systems for transforming raw materials into finished products, ensuring safety, quality, and cost-effectiveness. They apply principles from chemistry, physics, and mathematics to solve production problems and improve processes. Process engineering is essential in industries such as oil and gas, pharmaceuticals, food and beverage, and energy.

What is the difference between Process Engineering vs Chemical Engineering?

AspectProcess EngineeringChemical Engineering
Required CredentialsBachelor's in Chemical, Mechanical, or Industrial Engineering; often certifications like Six SigmaBachelor's or higher in Chemical Engineering; professional engineer (PE) license may be preferred
Work EnvironmentManufacturing plants, process facilities, industrial settingsResearch labs, chemical plants, design offices
Industry UsageFocuses on optimizing manufacturing processes and production efficiencyDesigns chemical processes, develops new chemicals, and research

Process Engineering primarily concentrates on improving and maintaining manufacturing processes within industrial settings, while Chemical Engineering involves designing chemical processes and developing new chemical products. Both roles require similar educational backgrounds and often overlap in industry applications, but their core focus areas differ.

What do process engineers do?

Process engineers design, develop, and optimize manufacturing processes to improve efficiency, safety, and quality. They analyze production systems, troubleshoot issues, and implement improvements using tools like process flow diagrams and statistical analysis. Their work often involves collaboration with other engineering teams and adherence to safety and environmental regulations.

What are some common challenges faced by process engineers when implementing process improvements in a manufacturing environment?

Process engineers often encounter challenges such as resistance to change from operators and staff, integrating new technologies with legacy systems, and ensuring that improvements do not disrupt ongoing production. Balancing cost-effectiveness with quality and safety standards can also be demanding. Successful process engineers collaborate closely with cross-functional teams, provide clear communication, and use data-driven approaches to overcome these obstacles and drive continuous improvement.

What are the key skills and qualifications needed to thrive as a Process Engineer, and why are they important?

To thrive as a Process Engineer, you need a solid background in engineering principles, process optimization, and problem-solving, typically supported by a degree in chemical, mechanical, or industrial engineering. Familiarity with process simulation software (like Aspen Plus or AutoCAD), Six Sigma certification, and experience with quality management systems are often required. Strong analytical thinking, effective communication, and teamwork are essential soft skills to excel in cross-functional projects and drive continuous improvement. These skills ensure efficient production processes, cost reduction, and consistent product quality within manufacturing or industrial environments.

Job description

Process Engineering Technician (Injection Molding)
Location: Buffalo Grove, IL
Pay: $28-37/hr
Shift Options:
  • 6:00 AM – 6:00 PM, 3/3/2 schedule (A Shift)
  • 6:00 PM – 6:00 AM, 3/3/2 schedule
Position Overview
We are seeking a strong Injection Molding Process Engineering Technician with hands-on mold setup and processing experience. This is not a press-monitoring role, this position requires ownership of setups, startups, troubleshooting, and technical support to engineering and production teams.

Responsibilities
  • Perform mold setup and full tool changeovers
  • Execute startups and validate processing parameters
  • Troubleshoot injection molding presses, molds, and tooling
  • Identify and resolve tooling vs. process-related issues
  • Adjust barrel temperatures, pressures, shot size, and cycle parameters
  • Process various resins, including proper material drying and moisture control
  • Support engineering with test runs, yield analysis, and process improvements
  • Monitor production performance and provide technical guidance to operators
  • Document process data and support continuous improvement initiatives
Required Experience and Skills
  • 5+ years of injection molding experience preferred
  • Strong mold setup experience (critical requirement)
  • Hands-on troubleshooting of presses and molds
  • Ability to restart tools and independently resolve downtime issues
  • Understanding of barrel and screw function and polymer processing fundamentals
  • Ability to work with minimal supervision and make sound technical decisions
  • Strong attention to detail and critical thinking skills
  • Scientific molding experience
  • RJG Master Molder certification or exposure
  • Experience supporting process engineering or development activities
  • Experience in cleanroom or regulated manufacturing environments
  • Background in medical, automotive, packaging, or similar molding environments
Qualified applicants will receive consideration for employment without regard to race, color, age, religion, sex, sexual orientation, gender identity, or national origin.
