About The Position

Thanks for your interest in Oklo! We are searching for Radiation Safety Officer (RSO) to join our team. This position will be positioned in the Austin, Texas area with >50% of travel. Position Description Atomic Alchemy, a wholly owned subsidiary of Oklo, is building scalable U.S. radioisotope production capabilities in facilities dedicated to producing essential isotopes for healthcare, industry, research, and defense. In May 2025, executive orders were issued directing the U.S. Department of Energy (DOE) to take a leading role in unleashing the American nuclear renaissance. Through these directives, DOE established the Reactor Pilot Program (RPP) to demonstrate at least three advanced reactors reaching criticality by July 4, 2026, or as soon as possible under the program. In August 2025, DOE selected Atomic Alchemy and awarded an RPP project for a pilot radioisotope production facility. We are seeking a Radiation Safety Officer to serve as the technical authority for radiation protection at one or more of our facilities. This role is designed for an experienced Certified Health Physicist (CHP) or an equivalently seasoned radiation protection professional who brings depth of judgment, and the ability to lead a mature radiation safety program. The Radiation Safety Officer owns the Radiation Protection Program and is expected to apply informed, technically rigorous decision-making in an operational nuclear environment. This role combines strategic program stewardship with hands-on engagement and offers meaningful influence over facility operations, licensing activities, and long-term safety culture.
