  • Apply first-principles engineering to design high-performance structural plastic and sheet metal components capable of withstanding static and dynamic mechanical loads
  • Own analysis, prototyping, and failure analysis efforts for plastic components
  • Fabricate first-of-a-kind plastic prototypes for mechanical fit checks and verification testing
  • Conduct validation testing to prove that designs meet critical requirements
  • Negotiate interface requirements with Battery Module and Electrode teams
  • Produce and release detailed 2D part and assembly drawings; define technical specifications (dimensional, functional, performance, manufacturing)

What You'll Bring

  • Degree in Mechanical Engineering, or related field; Bachelor's with 4+ years of industry experience
  • Experience with end to end product development, from concept to launch
  • Proficient in CAD and engineering analysis to drive design decisions
  • Strong data analysis skills, especially with respect to mechanical test results
