• Lead process validations including IQ/OQ/PQ activities, DOE studies, and process window development.
• Troubleshoot molding defects and implement corrective actions using data-driven methodologies.
• Support new product introductions from concept through production launch.
• Conduct mold design reviews and provide Design for Manufacturability (DFM) recommendations.
• Utilize Moldflow simulation tools to perform fill, pack, cooling, shrinkage, and warp analyses.
• Recommend improvements to gating, runner, cooling, venting, and ejection systems.
• Utilize advanced metrology systems including CMMs, optical inspection systems, and industrial CT scanners to validate part geometry and dimensional capability.
• Perform root cause analysis of dimensional variation through metrology data and statistical methods.
• Establish SPC, MSA (Measurement Systems Analysis), Gage R&R, and capability studies (Cp/Cpk).
• Collaborate with tooling, automation, quality, production, and customer teams.
• Evaluate and implement new manufacturing technologies, software platforms, and engineering tools.
• Other duties as assigned.

QUALIFICATIONS
