Radiation Safety Officer (RSO

Thanks for your interest in Oklo! We are searching for a Radiation Safety Officer (RSO) to join our team. This position will be on‑site in Idaho Falls, Idaho.

Oklo Isotopes is building scalable U.S. radioisotope production capabilities, dedicated to producing essential isotopes for healthcare, space, industry, research, and defense applications. In February 2026, Oklo’s Idaho Radioisotopes Laboratory (IRL) in Idaho Falls received its Material Possession License from the U.S. Nuclear Regulatory Commission (NRC), positioning us to lead in the manufacturing and distribution of beneficial radioisotopes in the U.S.

The Radiation Safety Officer will serve as the technical authority for radiation protection activities at the IRL. The role is designed for an experienced Certified Health Physicist (CHP) or an equivalently seasoned radiation protection professional who brings strong technical judgment, operational leadership, and deep expertise in radiation safety program implementation.

• Serve as the designated Radiation Safety Officer with technical authority and accountability for the IRL Radiation Protection Program in accordance with NRC requirements, applicable state regulations, and site procedures.
• Establish, maintain, and enforce radiation protection standards, radiological controls, and operational procedures using sound health physics principles.
• Provide technical oversight and guidance for radioactive material handling, isotope production activities, contamination controls, radioactive waste management, and radiological work planning.
• Lead, mentor, and develop radiation protection personnel, technicians, and operational staff to maintain a strong field execution and radiological safety culture.
• Perform and oversee complex radiological evaluations including shielding analyses, dose assessments, contamination control strategies, ALARA planning, and radiological work reviews.
• Integrate radiation protection requirements into facility modifications, operational procedures, commissioning activities, and infrastructure upgrades.
• Serve as the primary technical interface with regulatory authorities during inspections, audits, licensing activities, and regulatory communications.
• Help prepare, review, and approve regulatory documentation, license amendments, corrective action plans, radiological procedures, and radiation safety training programs.
• Lead investigations of radiological events, abnormal occurrences, and operational issues including root cause analysis and corrective action development.
• Support operational readiness, emergency preparedness, and commissioning activities associated with IRL operations.
• Partner with operations, engineering, maintenance, laboratory, and leadership teams to align radiation protection strategies with operational goals and long‑term facility objectives.
• Promote operational excellence, procedural compliance, industrial safety, and a strong nuclear safety culture.

• Bachelor’s degree in Health Physics, Nuclear Engineering, Radiochemistry, Chemistry, Physics, or a related technical discipline.
• Minimum of 10 years of progressively responsible experience in health physics, radiation safety, or radiological operations within regulated nuclear, isotope production, laboratory, or industrial environments.
• Demonstrated experience implementing and managing radiation protection programs in regulated radiological environments.
• Experience leading or supervising technical staff, including mentoring, training, and professional development.
• Strong working knowledge of NRC regulations, radiation protection principles, ALARA practices, contamination controls, and radiological work planning.
• Demonstrated ability to communicate effectively with regulators, senior leadership, and multidisciplinary technical teams.
• Strong technical writing, organizational, problem‑solving, and operational decision‑making skills.

• Certified Health Physicist (CHP) strongly preferred.
