Injection Molding Engineers - Troy, Michigan - Onsite

Job description:

This engineer will own the full lifecycle of injection molded components — from tooling concept and mold design through process development, production launch, and ongoing quality assurance — for body system applications across the vehicle.
What you get to do

• Review and approve mold designs, manage tooling builds with suppliers, and drive mold qualification (T1–T3 and beyond).
• Develop, validate, and document robust injection molding processes using scientific molding principles — establishing and locking process windows for pressure, temperature, fill rate, pack, hold, and cooling.
• Manage all aspects of injection molded components to meet program requirements including dimensional performance, functional sealing performance, cost, mass, cycle time, and manufacturability.
• Own component quality from mold qualification through production: lead PPAP submissions, develop control plans, drive root cause analysis on defects, and implement corrective actions to ensure zero-escape quality.

Qualifications

• Bachelor's Degree in Mechanical Engineering, Plastics Engineering, or related field from an ABET accredited university.
• 5+ years of hands-on injection molding engineering experience, spanning tooling design, process development, and production support for high-volume plastic components.
• Deep knowledge of injection mold tooling: cavity and core design, side actions, lifters, hot runner systems, cooling circuit layout, tool steel selection, and mold maintenance practices.
• Proficiency in scientific molding methodology, including systematic process development, DOE, and the use of SPC and process capability metrics to control part quality.
• Strong understanding of thermoplastic and thermoplastic elastomer materials (TPE, TPO, EPDM, PP, PA, PC/ABS) and how material properties affect shrinkage, warpage, sink, and functional performance.
• Demonstrated experience with quality systems and launch tools: APQP, PFMEA, control plans, PPAP, GD&T, MSA, and capability studies in a production injection molding environment.
• Familiarity with mold flow simulation software (Moldex3D, Autodesk Moldflow, or equivalent) and the ability to interpret results to drive tooling and process decisions.
