Essential Job Functions:

~ 60%

  • Execute machine, mold, and process validation activities (IQ/OQ/PQ) under the direction of Engineering and Quality.
  • Support validation documentation development as a technical SME, with primary responsibility focused on execution and data collection rather than document authorship or approval.
  • Collect, analyze, and document molding process data during validation studies and engineering trials.
  • Execute approved protocol activities and clearly communicate results, deviations, and observations.
  • Support implementation of new equipment, molds, and process changes on the molding floor.
  • Support implementation and operation of new vision cameras in molding, bristling and packaging. Specifically: physical installation, vision programming and integration. Final integration would include corresponding with a responsible Controls Engineer to make final connections.
  • Assist Engineering with continuous improvement initiatives through data‑driven analysis and experimentation.
  • Ensure all validation and engineering support activities comply with internal procedures and applicable regulatory requirements.
  • Communicate technical findings effectively to Engineering, Quality, and Manufacturing teams.
  • Provide hands‑on technical support to the Molding Department when not actively executing engineering or validation tasks.
  • Troubleshoot molding process issues related to quality, scrap, cycle time, and process stability.
  • Serve as a technical mentor to Process Technicians and Operators, reinforcing scientific injection molding principles and standard work.
  • Support Kaizen events and continuous improvement initiatives focused on safety, quality, delivery, and cost.
  • Assist with training efforts related to molding processes, validations, and best practices.
  • Act as a liaison between Engineering and Manufacturing to support effective communication and execution of process changes.
  • Help sustain process improvements through standardization and monitoring on the molding floor.

Knowledge/

Experience:
  • 5–10 years of injection molding experience, with the majority of time spent applying scientific injection molding principles.
  • Basic Vision system experience, understanding of how vision tools work and open to formal training.
  • Hands‑on experience in setting, optimizing, and troubleshooting injection molding processes using data‑driven methodologies.
  • Experience supporting or executing machine, mold, and process validations in a regulated manufacturing environment (medical device preferred).
  • Strong understanding of process capability, DOE fundamentals, and molding process robustness.
  • Proven ability to work effectively in a fast‑paced, hands‑on manufacturing environment.
  • Experience supporting cycle time reduction, scrap reduction, and continuous improvement initiatives.
  • Strong written and verbal communication skills with the ability to clearly document technical activities and results.
