What You'll Do (Responsibilities):
-
Lead suppliers in developing optimized molding processes that produce high-quality parts with reduced cycle times.
-
Create and manage tool concept sheets for critical plastic parts and molds, integrating them into cost estimation workflows.
-
Validate tooling through closed-loop feedback and standardized manufacturing engineering practices.
-
Continuously improve mold tooling and manufacturing processes with Tier I suppliers and internal teams, aligning with GM global standards.
-
Support Strategic Tooling Initiatives (STI) to deliver high-value solutions in collaboration with suppliers.
-
Establish transparent workflows between tool concept inputs and cost outputs.
-
Develop and train others on best practices for injection-molded parts.
-
Partner with Product Engineering teams to implement effective design and manufacturing strategies.
-
Apply expertise in Class-A surface appearance requirements for molded, painted, chromed, or metalized automotive parts.
-
Formulate cost-effective, high-quality solutions by optimizing part design, tooling, and processing variables.
-
Collaborate globally to develop plastic part and tool designs that meet cost and quality goals.
-
Use mold filling analysis software to deliver design solutions that reduce mold debug time and improve part quality
Your Skills and Abilities (Required Qualifications):
-
Hands-on experience with plastic processing and/or tooling.
-
Proficiency in Unigraphics NX or equivalent CAD software.
-
Familiarity with injection mold filling analysis tools such as Autodesk Moldflow.
-
Bachelor’s degree in Plastics Engineering, Mechanical Engineering, Manufacturing Engineering, or a closely related field.
What Can Give You a Competitive Edge (Preferred Qualifications):
-
5+ years of experience in plastic processing and/or tooling.
-
MS in Plastics or Mechanical Engineering and/or MBA.
-
Autodesk Moldflow Associate or Professional Certification.
-
Design for Six Sigma Green or Black Belt Certification.
-
Background in scientific molding and process control (e.g., RJG).
-
Experience with statistical techniques such as Six Sigma.
-
Proficiency in formal problem-solving methods such as Shainin and/or Design of Experiment (DOE)
-
Multilingual communication skills (Spanish, Portuguese, German, Korean, and/or Chinese).
