In this role, you will collaborate with the entire company including controls and software engineers, scientists and strategists to develop the systems that will revolutionize agriculture.

Type of Role


What You'll Do

  • Create cost-effective, fast, reliable equipment, and support it through validation and production handoff

  • Collaborate with engineering product managers/systems engineering to ensure all design requirements are met, and quantify and execute appropriate validation testing

  • Work closely with controls engineers to integrate sensors, electromechanical actuators, pneumatic controls, field IO, etc.

  • Get hands-on to design, build, and test rapid proof of concept prototypes

  • Independently execute on and troubleshoot designs, as well as mentor other members of the team in solving technical problems

  • Own final design of key systems for a production-ready machine, including assembly, maintenance, and cleanability considerations

  • Create and maintain 2D part drawings, assembly drawings, and BOMs

  • Generate other necessary documentation for design validation/production release (design requirements docs, FMEAs, final SOPs, spare parts lists, etc.)

What We're Looking For

  • Mechanical engineering degree (or similar)

  • Experience owning at least two subsystems or machines through all product cycles(concept through production release)

  • Experience with manufacturing/processing equipment and validating that equipment meets process parameters

  • Experience designing for several manufacturing processes, i.e. machining, sheet metal processing, welding; strong knowledge of materials and finishes

  • Strong knowledge of pneumatic and electric actuators, sensors, and other components typically used in industrial equipment

  • Extensive experience creating 3D CAD and 2D drawings, including familiarity with using and creating templates

  • Excellent internal and external communication skills, including a strong understanding of how the product you will be working on interfaces with and affects other parts of the farm

  • Comfortable leading cross-functional design reviews and FMEA activities

  • Ability to understand and adapt to flexible and evolving design requirements, as well as tight time constraints

  • Experience designing equipment for food/washdown/other harsh environments is a plus

  • Experience with industrial robots, machine vision, or PLC programming is a plus
