Machinist / Prototype Fabrication Engineer
About The Position
Becoming is building a technology platform at the intersection of developmental biology, engineering, and AI, and needs highly customized hardware to support its work. The Machinist / Prototype Fabrication Engineer will work directly with engineers and scientists to rapidly turn designs into physical hardware. This is primarily an R&D and prototyping role rather than conventional production manufacturing, suited to someone who enjoys rapid iteration, unusual engineering challenges, and close collaboration with the people designing and testing the hardware. The role focuses on machining precision components and building custom hardware for experiments, from CAD, engineering drawings, sketches, or early-stage concepts through fabrication and inspection. The engineer will advise on manufacturability and fabrication choices, modify parts in response to experimental results, and support assembly, troubleshooting, repair, and modification of experimental hardware. The position will also help establish a strong internal rapid-prototyping capability. Success means helping move ideas from CAD to experiments dramatically faster by fabricating, testing, modifying, and rebuilding difficult hardware under one roof.
Requirements
- Substantial hands-on machining experience.
- High capability with CNC milling and/or turning.
- Comfort with manual mills and lathes.
- Ability to independently take a component from drawing or CAD through fabrication.
- Understanding of GD&T, tolerancing, fits, surface finishes, and inspection.
- Strong intuition for manufacturability.
- Comfort working across metals and engineering polymers.
- Enjoyment of working directly with engineers in a fast-moving R&D environment.
- Exceptional pride in the quality of physical things built.
