Head Of People Operations

Atomic Machines is ushering in a new era of micromanufacturing with its Matter Compiler technology platform. This platform enables new classes of micromachines to be designed and built by providing manufacturing processes and a materials library that are inaccessible to semiconductor manufacturing methods. It unlocks MEMS manufacturing not only for device classes that could never be produced by semiconductor methods, but also for entirely new categories. Furthermore, this digital platform is fully programmable in the way 3D printing is digital-but whereas 3D printing produces parts of a single material using a single process, the Matter Compiler technology platform is a multi-process, multi-material system: bits and raw materials go in, and complete, functional micromachines come out. The Atomic Machines team has also created an exciting first device-made possible only through the Matter Compiler technology platform-that we will be unveiling to the world soon.

Our offices are in Emeryville and Santa Clara, California.

About the Role:

Atomic Machines is at an exciting inflection point. As we scale beyond 250 employees and continue expanding across multiple locations, we're looking for a strategic builder to design and lead the next generation of our People Operations function.

You'll lead People Operations, People Programs, HR systems, and employee experience initiatives while partnering closely with our HR Business Partner, Head of Strategic Growth, IT, and executive leadership to ensure our people infrastructure evolves alongside the business.

This is a unique opportunity for someone who loves creating from the ground up. You'll evaluate new technologies, modernize processes, implement scalable systems, and design programs that support a diverse workforce spanning engineering, operations, research & development, manufacturing, and corporate functions across multiple locations.
