• Analyze trends, validate root causes, and deploy prevention systems that stabilize supplier molding capability.

Process Capability & Statistical Control

• Validate molding process capability using Cp/Cpk, DOE, control charts, and other statistical methods.
• Ensure suppliers maintain repeatable, predictable molding parameters with robust process windows.

Leadership, Influence & Cross‑Functional Collaboration

• Partner with engineering, purchasing, and quality teams to communicate technical insights and influence supplier decisions.
• Support risk assessment, technical reviews, and supplier transition efforts.

Risk Management

• Identify and mitigate risks related to tooling, process variation, capacity, and supplier stability.

TOOLS you’ll bring with you:

• BS in Plastics Engineering Technology or equivalent; RJG Master Molder I/II strongly preferred.
• Minimum 5 years hands‑on thermoplastics processing experience.
• Strong understanding of mold design, tooling principles, material data, and injection molding processes.
• Demonstrated leadership in complex project execution within cross‑functional environments.
• Experience with supplier management, including assessment, auditing, development, performance evaluation, and improvement planning.
• Working knowledge of Quality Management Systems (QMS), including NCMR, SCAR, PPAP, APQP, FMEA, and root cause methodologies.
• Travel required up to 25-50% domestically and internationally, sometimes on short notice

Other TOOLS we prefer you to have: 

• Professional certifications (e.g., Lean, Six Sigma Green Belt).
