Environmental Health & Safety (EHS) Generalist

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.

The EHS Generalist will support day-to-day regulatory compliance, hazard controls, and site safety operations. This role focuses on high-risk safety programs—including Lockout/Tagout (LOTO), Confined Space Entry, and Respiratory Protection—while auditing, updating, and writing technical EHS documentation to maintain Cal/OSHA compliance. Experience with hazardous waste management preferred.

It is desired to possess the ability to be present/support the night shift or transition in the morning or evenings when needed.

Responsibilities -

Be the Trusted Face of Safety: Spend most of your day in manufacturing and R&D areas, building rapport with operators, technicians, and contractors while identifying hazards and resolving them immediately, or partnering with engineers and leadership on lasting fixes.

-

Lead Our Safety Culture Change: Act as a change agent as we grow from startup to full production. Apply HOP principles and behavior-based safety to encourage open reporting, learning from near misses, communicating lessons learned and safe habits that people own rather than have imposed on them.

-

Own Core Programs and Procedures: Manage and audit our Lockout/Tagout (LOTO), Confined Space Entry, and Respiratory Protection programs, and author, review, and modernize SDS, SOPs, JHAs, and emergency response plans using technical resources and data to keep them clear and usable on the floor.

-

Train and Coach: Deliver site-specific EHS training and onboarding to employees and contractors, and reinforce it through everyday conversations and in-the-moment coaching on the floor.

-

Walk, Investigate, and Stay Compliant: Join leadership facility walkthroughs to surface compliance gaps, lead audits and incident investigations that focus on learning why and how things happened rather than assigning blame, and maintain records that keep us fully compliant with Cal/OSHA, EPA, and Bay Area regional environmental regulations.

Requirements -

Education & Certification: Bachelor’s degree in safety, industrial hygiene, occupational health, or similar. CSP designation required (or actively in the process of obtaining it); CIH is a plus. Training or certifications in DTSC, DOT, RCRA, BAAQMD, CUPA, HAZWOPER, Emergency Response, First Aid/CPR/AED, etc. are valued.

-

Experience: 3+ years of EHS experience in any production-related environment, such as manufacturing, tech hardware, chemical, or foundry. Experience in a fast-growing or scaling operation is a plus. Experience working with San Francisco Bay Area and Northern California regulators (Cal/OSHA, BAAQMD, DTSC, local CUPA).

-

Technical Mastery: Deep hands-on experience with LOTO procedures, permit-required confined spaces, respiratory protection, and PPE standards.

-

Technical & Documentation Savvy: Demonstrated strength in drafting, reviewing, and improving EHS policies, JHAs, and SOPs, and comfort using technical resources and data to build procedures that work in practice.

-

Culture-Building & Communication: Working knowledge of safety culture concepts such as HOP, behavior-based safety, and human factors, with strong interpersonal and influencing skills. You build trust with everyone from front-line employees, contractors to company executives, across shifts, and can lead change in a fast-evolving environment.
