Job Description

Job Description
Benefits:
  • 401(k)
  • Employee discounts
  • Health insurance

Work Authorization Requirement
Applicants must be authorized to work in the United States on a permanent basis. We are unable to offer visa sponsorship at this time.


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.
