About The Role

We are hiring a Senior Mechanical Engineer to design, develop, test, and validate our next generation of food manufacturing systems. In this role, you will help scale R&D discoveries into novel food processing equipment and play a key part in delivering food-safe systems for our first product launches while laying the foundation for future hardware scale-up. You’ll lead portions of hardware design, development, and validation, and create and maintain food safety documentation for equipment.

What You’ll Do

  • Design, develop, and validate food processing equipment from concept through commercialization
  • Translate R&D learnings into scalable, manufacturable systems
  • Create and maintain food safety documentation aligned with regulatory standards
  • Lead and support hardware builds, testing, and iteration cycles
  • Troubleshoot equipment and process issues in real-time to keep production running
  • Work cross-functionally with internal teams, co-manufacturers, and external partners
  • Contribute to the development of new systems that support future production scale

What We’re Looking For

  • 5+ years of experience in mechanical engineering, ideally in food process scaling or systems development
  • Strong CAD experience (Onshape preferred; also SolidWorks, Siemens NX, etc.)
  • Experience designing sanitary food equipment within regulatory guidelines (BOH, DPH, GMP, FDA, NSF)
  • Ability to solve complex, ambiguous problems and operate effectively in unknown territory
  • Hands-on troubleshooting skills across mechanical systems (motors, seals, components, etc.)
  • Experience leading projects end-to-end in fast-paced environments
  • Strong collaboration skills across technical teams and external partners
  • A startup mindset — adaptable, hands-on, and excited to take ownership

Nice to Have

  • Experience working with novel or first-of-its-kind manufacturing processes
  • Background working with co-manufacturers or scaling early-stage hardware
  • Exposure to food-grade equipment design and validation at commercial scale

Why Join Us?

  • Inclusive and fun work culture
  • High ownership and impact in a fast-growing startup
  • Equity package
  • Unlimited PTO (that people actually take), Vision, Dental, 401k
