INNOVATE WITHOUT BOUNDARIES! At Milwaukee Tool, our People and our Culture drive everything we do. Our teams bring a passion to never settle and continuously improve, delivering high-quality products that positively impact our users. This mindset is central to how we approach manufacturing excellence every day.
This role supports injection molding operations through hands-on technical expertise, process ownership, and close collaboration with production, automation, and maintenance teams.

  • Participate in mold setups, startups, and changeovers to support production, validate process intent, and assist setup technicians during complex or abnormal conditions.
  • Troubleshoot, diagnose, and correct process-related issues using structured root-cause methods rather than symptom-based adjustments.
  • Document, track, and report mold, process, automation, and equipment-related issues, ensuring information is accurate and actionable.
  • Communicate and appropriately escalate production issues to ensure quality, safety, and on time delivery commitments are maintained.
  • Lead, mentor, and develop setup technicians, providing technical guidance and assisting with work direction during startups, changeovers, and abnormal conditions.
  • Maintain, and improve process documentation, including setup sheets, work instructions, operational guidelines, and troubleshooting aids.
  • Effectively prioritize and manage multiple concurrent technical activities in a fast-paced production environment.
  • Adhere to timelines while maintaining strong attention to process discipline, safety, and quality requirements.
  • Perform other duties as assigned that support manufacturing and engineering objectives.

The TOOLS you'll bring with you:
  • Associate's Degree (preferred) in Industrial Automation, Mechatronics, Plastics Technology, or completion of an Injection Molding Apprenticeship or equivalent technical training.
  • Minimum of 5 years of hands-on experience setting up, troubleshooting, and supporting injection molding production processes.
  • Solid understanding of mechatronic systems, including hydraulics, pneumatics, sensors, and electrical components as applied to manufacturing equipment.
  • RJG Master Molder I or II certification preferred or demonstrated equivalent knowledge of scientific molding principles.

Our Perks and Benefits:
  • Legendary Company Culture
  • Robust health, dental and vision insurance plans
  • Generous 401 (K) savings plan
  • Education assistance
