HR Business Partner, Manufacturing

Our mission at Atomic Machines is to bring autonomous bits-to-atoms manufacturing of anything at any scale to the world, and we are well on our way.  We are developing an entirely new class of manufacturing foundry for micro- and nano-scale machines, and we are using that foundry to create products the world has heretofore been unable to build.  Our first device has exceptionally strong and large-scale product-market fit: it is both iconic of what our platform can do and a driver of very significant enterprise scale.

Joining forces with us means becoming part of an incredibly talented, inventive and passionate multi-disciplinary team running hard to make our platform, devices and vision a reality.  You will have the opportunity to help define the company from its earliest days. You'll be challenged to learn and grow as a builder and a leader as the company itself grows rapidly. And you will receive significant equity compensation - you'll truly be a company owner and benefit financially from our overall success. 

Our offices are in Emeryville and Santa Clara, California.

You'll partner closely with leaders and employees, translating business priorities into high-impact people strategies that improve performance, engagement, and retention. You'll use data to spot trends, anticipate challenges, and help leaders look around corners, while also being a trusted, visible presence with a strong pulse on the organization.

• Own and optimize HR systems, regularly assessing effectiveness and ensuring we maximize their value as we scale.
• Maintain deep knowledge of California employment laws and best practices, mitigating risk and ensuring compliance; partner with external legal counsel as needed.
• Lead the design and delivery of management and leadership development programs, leveraging AI-enabled tools, learning platforms, and data-driven insights to scale high-quality training and support leaders as the organization grows.

What You'll Need:

• 5 - 10 years of progressive HR Business Partner or HR leadership experience, ideally within a fast-growing, technical startup environment; hardware experience is a plus.
• A strong passion for people - paired with the ability to balance empathy, business needs, and sound judgment.

• Excellent communication and influencing skills, including experience partnering with and presenting to senior leaders.
• High discretion, sound judgment, and a strong ethical foundation.
• Comfort navigating ambiguity, change, and competing priorities in a rapidly evolving environment.
