Job Description

Diamond Foundry Inc. is solving the thermal limitation at the foundation of today's most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. We have managed to produce the world's first single-crystal diamond wafers and are now on a mission to put a diamond behind every chip. We are the rare unicorn that has grown fast and profitably. We received $515m in funding and are executing a multi-$B expansion plan for one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy.

We’re looking for a People & Culture Generalist to support a fast-paced, high-trust startup environment in a highly technical manufacturing company.

This role spans HR operations, employee relations (ER), HR compliance, HRIS management, and employee lifecycle support across both hourly manufacturing/technician teams and salaried engineering and corporate staff.

This is an opportunity to help build and scale People Operations infrastructure at a fast-growing organization where your ideas, judgment, and execution will directly influence employee experience and company culture.

You’ll need strong judgment, discretion, and the ability to connect day-to-day HR work to broader business needs.

• Partner with managers and leadership to support employee experience, team effectiveness, and organizational growth
• Own and improve core People Operations processes across the employee lifecycle, including onboarding, offboarding, and HR systems administration
• Build and scale HR policies, workflows, and infrastructure with an ownership mindset and focus on continuous improvement
• Manage employee relations matters with professionalism, sound judgment, and discretion
• Ensure compliance with federal, state, and local employment laws and HR best practices

• 3–6 years of experience in HR Generalist, People Operations, or HRBP-adjacent roles
• Strong knowledge of HR compliance, California labor law, and FLSA classification (hourly vs. salaried)
• Experience handling employee relations (ER), investigations, and confidential matters
• Experience supporting both hourly and salaried employee populations, ideally in manufacturing, engineering, or technical environments
• Familiarity with HRIS systems (e.g., Rippling, BambooHR, Workday, Gusto, or similar) and comfort working in fast-paced, high-growth environments

Actual compensation will be determined based on experience, expertise, and scope of responsibilities. Higher-level candidates will be considered, with adjusted salary as appropriate.
