POSITION OVERVIEW

This is an entry-level engineering role designed for recent graduates (A.S. or B.S.) who are eager to apply their technical education in a hands-on manufacturing environment. You will work alongside our experienced Process Engineers and Production team to learn, analyze, and optimize injection molding operations from the ground up.

The ideal candidate is analytically minded — someone who enjoys reading data, identifying root causes, and engineering a solution. If you graduated with a technical degree and want to see your problem-solving skills, make a real measurable difference on a production floor, this role is for you.

• Apply statistical and analytical thinking to real production data every day

• Interpret process parameters, blueprints, and quality specifications — then act on them

• Develop troubleshooting skills in a structured, mentored environment

• Build a foundation in plastic injection molding process engineering with a clear path to growth

• Work in a modern, state-of-the-art facility with advanced equipment and metrology capabilities

JOB DUTIES AND RESPONSIBILITIES

Process Analysis amp; Problem Solving

• Monitor and analyze machine, mold, and material data to identify deviations from standard and determine corrective action

• Troubleshoot machine, mold, and material problems using structured analytical approaches — gather data, form a hypothesis, test, iterate

• Perform running adjustments to maintain maximum production quality and minimize scrap; document findings and outcomes

• Consistently review nonconforming materials and assist in root cause analysis to drive scrap levels to acceptable targets

• Work closely with the Process Engineer to address difficult processing challenges and pursue continuous improvement

Setup amp; Operations

• Support machine start-ups: install molds in presses and make all required connections, adjustments, and settings per established documentation

• Assist with setup and operation of secondary equipment including sonic welders, thermolators, conveyor belts, drill presses, and gate cutters

• Act as first responder to machine, robot, thermolator, and secondary equipment alarms — assess, escalate, or resolve

• Ensure machines and robots are running at optimum efficiency throughout the shift

Data Interpretation amp; Documentation

• Interpret specifications, blueprints, and engineering drawings to determine whether parts produced meet defined standards

• Maintain setup documentation and record all machine adjustments during processing for traceability and continuous improvement

• Monitor the production board and production priorities; communicate proactively when schedule changes affect shift operations

• Verify that materials and production paperwork are on hand and aligned with production goals

Team Collaboration amp; Development

• Collaborate with Operators, Process Engineers, and Quality Technicians to meet quality and throughput standards

• Assist the Process Engineer in training Setup and Material Handling personnel on process, equipment, and safety best practices

• Contribute ideas to improve production methods, working conditions, equipment performance, and team efficiency

• Perform other related duties as required or assigned

EDUCATION amp; QUALIFICATIONS

• Associate or Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Plastics Engineering Technology, Industrial Engineering, or a closely related technical field — required

• Recent graduates (0–2 years of experience) strongly encouraged to apply; internship or co-op experience in manufacturing is a plus

• Strong analytical and problem-solving skills — you know how to read data and draw a conclusion

• Ability to read and interpret engineering drawings, blueprints, and technical specifications

• Comfortable in a fast-paced, dynamic environment with shifting priorities

• Strong written and verbal communication skills

• Self-starter who can work independently once oriented and trained

• Knowledge of or coursework in GD amp;T, SPC, lean manufacturing, or plastics processing is a plus — not required
