Plastic Injection Molding Engineer(Moldex3D, Autodesk Moldflow,)
Listed pay for BS-level Process Engineering roles on Crosslinked center on $111k (486 with a salary).This posting does not list one.
Develop and validate injection molding processes and tooling for EV body components
Worth knowing
Why it is interesting. Hands-on with scientific molding and mold flow simulation for high-volume EV plastic components.
Might not be for you. Requires 5+ years of injection molding engineering experience, not for early-career.
Core polymer roleDeep knowledge of injection mold tooling... thermoplastic and thermoplastic elastomer materials (TPE, TPO, EPDM, PP, PA, PC/ABS)... shrinkage, warpage

What You Get To Do
- Be an integral part of an energetic team that's redefining what an electric vehicle can be, with injection molded components at the heart of the body system.
- 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.
- Collaborate with design, manufacturing, and supplier engineering teams to execute DFM reviews, mold flow analysis, and tolerance studies that eliminate risk early in development.
What You Bring To The Team
- 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.
- Excellent communication and collaboration skills with the ability to manage multiple suppliers and cross-functional priorities in a fast-paced, startup environment.
