  • Maintain, modify, and optimize the equipment and tools with vendor's guidelines

What you bring to this role:
  • Advanced degree in mechanical or chemical engineering or related field
  • 5+ years of experience in a cell fabrication role in a Li ion battery industrial environment
  • Group leading experience is preferred
  • Hands-on experience with multi-layer large format pouch cell assembly processes
  • Experience with all-solid-state-battery development is strongly preferred
  • Experience of vendor qualification and customer interactions
  • A desire to hold your own in a fast-moving environment alongside highly technical peers
  • Ability to work safely and in compliance with all regulations and quality systems

We are happy to offer our team members:
  • Competitive salary versus leading employers in industry, commensurate with experience
  • Medical, dental, and vision insurance
  • Generous employee stock options
