Body Systems Injection Molding Engineer - Process Leader

Fast Switch, Ltd.; Michigan; On-site; USD 90,000 - 120,000; Full time

Job summary

FastTek Global in Michigan is seeking a hands-on Injection Molding Engineer to own the full lifecycle of body-system components—from tooling concept and mold design to process development, production launch, and ongoing quality assurance.

You will drive mold qualification, establish process windows (pressure, temperature, fill, pack, hold, cooling), manage all quality and manufacturability metrics, and collaborate with design, manufacturing, and suppliers to ensure robust, cost-effective

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 in tooling design, process development, and production support.
• Deep knowledge of injection mold tooling: cavity and core design, side actions, lifters, hot runner systems, cooling circuit layout.
• Proficiency in scientific molding methodology, including DOE, and the use of SPC and process capability metrics.
• Strong understanding of thermoplastics and related materials and how properties affect shrinkage and performance.
• Experience with quality systems and launch tools: APQP, PFMEA, control plans, PPAP, GD&T, MSA, and capability studies.

Responsibilities

• 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 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, 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.
• Collaborate with design, manufacturing, and supplier engineering teams to execute DFM reviews, mold flow analysis, and tolerance studies that eliminate risk early in development.
