Plastics Engineer

About the role

You will own the end to end development and optimization of plastic injection molding processes that directly support new product introductions and long term production programs. You will lead cross functional investigations and implement data driven improvements that enhance quality, reduce scrap, and increase overall equipment effectiveness. You will act as the primary technical leader for tooling, molding trials, and process qualification activities across multiple projects. You will partner closely with Engineering, Tooling, Quality, and Manufacturing teams to align on root cause analysis and corrective action plans. You will evaluate and recommend plastic materials and resins based on performance, manufacturability, and cost targets. You will utilize scientific molding principles and statistical methods to establish robust, repeatable processes that meet demanding customer specifications. You will provide technical leadership, training, and mentorship to Process Technicians, Mold Technicians, and production personnel.
