Atomic Machines is ushering in a new era of micromanufacturing with its Matter Compiler technology. This full-stack technology 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. It promises to unlock MEMS manufacturing for the many device classes frustrated by semiconductor methods and to open up entirely new product classes. The Matter Compiler technology fully realizes the digital manufacturing dream: 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 technology - that we will be unveiling to the world soon. Our offices are in Emeryville and Santa Clara, California. About the role: This role will begin 8:30am - 5:00pm to support initial ramp-up and training.
