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: As the Head of People Operations, you will be a key operational leader and cultural steward, responsible for implementing scalable systems that shape how we work and grow together. You will partner closely with the VP, People & IT and functional leaders to ensure the company’s strategy is reflected in our people practices—distilling objectives into clear pillars, annual and quarterly OKRs, team metrics, and individual scorecards that create transparency and alignment across the organization. You will embed our values and cultural behaviors into every stage of the employee lifecycle, from hiring and onboarding to performance, rewards, and communications—making sure every Atomizer feels connected to the mission and managers lead with consistency and fairness. You’ll develop career frameworks, leadership programs, and development pathways that unlock potential at every level, while also building systems that scale as the company grows. By maintaining a unified playbook for managers, you will help establish clarity on “how we do things here” and ensure the employee experience is consistent, equitable, and inspiring. At the same time, you’ll be responsible for monitoring organizational health risks, bringing forward data-driven insights, and advising leadership on decisions that impact people and culture.
