  • Support pneumatic and electrical design, with guidance from senior engineers

  • Work with domestic and offshore integration partners on the build and deployment of robotic cells

  • Contribute to feasibility and cost analyses for new mechatronic systems

  • Draft and maintain technical specifications

  • Test and characterize electromechanical and optical systems

  • Troubleshoot electrical and mechanical issues to keep equipment ready for demos and development

Experience and Skills You'll Need
