Job description

Manufacturing Manager
Injection Molding | Leadership Development | Path to Plant Manager
We are seeking a Manufacturing Manager to lead production operations at a growing injection molding facility east of Philadelphia.
This is much more than a traditional production management role. This hire is a succession plan to develop into the Plant Manager role in 4 years. The successful candidate will gain exposure to all aspects of running a manufacturing operation while leading daily production.
Why This Opportunity Stands Out
  • Clearly defined succession plan to become Plant Manager
  • Direct mentorship from an experienced Plant Manager
  • Approximately 45-person manufacturing facility
  • Continued investment in new injection molding equipment, including clean room manufacturing capabilities
  • Opportunity to broaden leadership responsibilities beyond production into overall plant operations
Responsibilities
  • Lead day-to-day production operations to achieve safety, quality, delivery and productivity objectives.
  • Drive Lean Manufacturing, 5S and continuous improvement initiatives throughout the operation.
  • Coach, mentor and develop supervisors and production personnel.
  • Optimize labor utilization, workflow and manufacturing efficiency.
  • Partner with Scheduling, Engineering, Quality, Maintenance and Customer Service to ensure customer expectations are met.
  • Support new product introductions and manufacturing process improvements.
  • Monitor production metrics including efficiency, scrap, quality and labor performance.
  • Foster a culture of accountability, teamwork and continuous improvement.
Qualifications
  • Strong leadership experience within an injection molding manufacturing environment.
  • Solid understanding of injection molding processes, tooling and production operations.
  • Experience leading supervisors and production teams.
  • Background implementing Lean Manufacturing and continuous improvement initiatives.
  • Ability to develop people while driving operational performance.
  • Excellent communication and problem-solving skills.
Compensation
  • Base salary: $140,000-$170,000
  • Bonus opportunity
  • Relocation assistance available for the right candidate

This opportunity is ideal for an ambitious manufacturing leader who wants to move beyond production management and prepare for full Plant Manager responsibilities over the next several years.
