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.

This role reports to the Head of Engineering.

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 Solid Works, 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
What Success Looks Like
  • Reliable, scalable equipment supporting early product launches
  • Fast iteration cycles that improve system performance and manufacturability
  • Strong documentation and adherence to food safety standards
  • Effective troubleshooting that minimizes downtime and keeps production moving
  • Seamless collaboration across engineering, operations, and external partners
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
