  • Some experience with injection molding, automation, or IML labeling is a big plus
  • Ability to read machine instructions and troubleshoot issues logically
  • Willing to work in a fast-paced manufacturing environment and respond to machine downtime quickly
  • Able to lift up to 50 lbs and work on your feet throughout the shift

Bonus Skills (Nice to Have):
