Contact: Supriya Krishnan Contact Email: supriya_k@depusa.com]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 (Moldex 3D, 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. Skillsinjection molding
