Senior Mechanical Engineer
Build something that’s never been built before. Join a small team turning breakthrough food tech into real products, and own the systems that make it happen.
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 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
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
