A growing plastics manufacturer is seeking an experienced, hands-on Process Engineer to support injection molding operations. This role is responsible for developing, validating, and optimizing molding processes to ensure stable, capable, and efficient production.

This is a highly technical, manufacturing-floor–driven position. The ideal candidate must have direct injection molding processing experience and be comfortable working at the press—not just behind a desk.

Key Responsibilities

• Develop and validate injection molding processes for new and existing tooling using scientific and decoupled molding principles.
• Optimize molding parameters to improve quality, cycle time, throughput, and scrap reduction.
• Establish and maintain documented process standards and startup parameters.
• Perform machine startups, shutdowns, and in-depth troubleshooting of presses, molds, and auxiliary equipment.
• Conduct DOE’s, capability studies, and tooling qualifications.
• Provide daily technical support for production, sampling, and quality-related concerns.
• Identify opportunities for mold improvements, equipment upgrades, and cost reduction initiatives.
• Partner cross-functionally with Production, Engineering, and Quality teams to maintain process stability.
• Train and mentor mold setters, technicians, and operators on proper processing techniques.
• Support quoting, trials, and technical discussions with customers or suppliers as needed.
• Ensure compliance with applicable quality and environmental management systems.

Required Qualifications

• Two-year technical degree or equivalent hands-on experience.
• Minimum 8 years of experience in an injection molding environment.
• At least 5 years of direct plastic injection molding processing experience.
• Demonstrated expertise in Scientific Injection Molding techniques.
• Strong troubleshooting and root-cause analysis skills.
• Ability to read blueprints and use precision measuring instruments.
• Experience conducting DOE’s and process capability studies.
• Working knowledge of lean manufacturing principles preferred.
• Proficiency with standard Microsoft Office tools.
• Strong communication and leadership skills with the ability to train others.

Work Environment & Expectations

• Manufacturing-floor–focused role with extensive hands-on involvement.
• Regular standing and movement in a production environment that may include heat, noise, and industrial conditions.
• Strong commitment to safety and process discipline.
• Expected to lead technical initiatives and respond quickly to production needs.

Benefits & Growth Opportunities

• Competitive compensation package
• Medical, dental, and vision coverage
• Company-paid short- and long-term disability
• 401(k) with employer match
• Paid time off and paid holidays
• Tuition reimbursement
