From bits to atoms. Backed by Accel, Lightspeed and a16z.
About the role
Periodic Labs is building an AI that can simulate science and verify its own predictions — training on the full scientific method. Central to that mission is a high-throughput experimental materials science lab that handles hazardous chemistries, high-pressure and high-temperature processes, air-sensitive synthesis, toxic gas exposure risks, and an expanding suite of thin-film deposition tools including PVD and PLD. The complexity of what we run overnight and autonomously increases every month. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- 7–10+ years of experience in EHS, process safety, or chemical operations in labs, pilot plants, or semiconductor fabs, preferably with a strong chemistry background (solid-state chemistry, materials processing, or lab automation a plus)
- Hands-on experience leading HAZOPs or FMEAs and running PSSR and MOC programs
- Working knowledge of functional safety: interlocks, safety PLCs, and ISO 13849 / IEC 61508 concepts
- Working knowledge of Cal/OSHA, OSHA PELs, ACGIH TLVs/BEIs, NIOSH, and ANSI standards
- Comfort working on-site in a fast-paced, high-complexity lab environment where experiments run 24/7 and the hazard profile evolves as new processes and equipment are introduced

The complexity of what we run overnight and autonomously increases every month.
We believe EHS is integral to this ambition, not a compliance function bolted on after the fact, but a core design discipline that makes autonomous science possible. This role focuses on operational safety: making sure every new process, tool, and autonomous workflow is hazard-reviewed, safe to start up, and safe to run...
