Staff Mechanical Engineer
Atomic Machines Emeryville, CA, USA
Atomic Machines is ushering in a new era in micromanufacturing with its Matter Compiler (MC) technology. The MC enables new classes of micromachines to be designed and built by offering manufacturing processes and a materials library that is inaccessible to semiconductor manufacturing methods. The MC promises to unlock MEMS manufacturing both for the many device classes that never could be made by semiconductor methods but also to open up entirely new classes. Furthermore, the MC is fully digital in the way 3D printing is digital, but where 3D printing produces parts of a single material using a single process, the MC is a multi-process, multi-material technology: bits and raw materials go in and complete, functional micromachines come out. The Atomic Machines team has also created an exciting first device - one that was only made possible by the existence of the Matter Compiler - that we will be unveiling to the world soon. Our offices are in Emeryville and Santa Clara,...
