Reactor Operator

Thanks for your interest in Oklo! We are searching for Reactor Operators to join our team.

This position will be on-site in the Austin, Texas area.

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 looking for highly qualified Senior Reactor Operator (SRO) and Reactor Operator (RO) candidates. Operators (SRO/RO) are responsible for the safe and precise manipulation of facility controls to support commissioning, initial startup, testing, and ongoing operational activities. This role requires hands‑on operation and maintenance of reactor and facility systems, adherence to detailed procedures, and continuous monitoring of reactor parameters to ensure safe and compliant performance.

Operators will play a critical role in bringing the facility from pre‑operational testing through initial criticality and into operations.

Successful candidates will be detail‑oriented, disciplined, and capable of executing operational tasks in a high‑reliability environment. The role requires strong technical aptitude, sound judgment, and the ability to maintain focus during dynamic facility conditions. This is an on‑site, hands‑on position that will work closely with other operational and engineering personnel to ensure the facility operates safely and efficiently.

• Operate, or direct the operation of, reactor and facility systems in accordance with approved procedures, technical specifications, and safety standards.
• Perform hands‑on manipulation of facility controls, including reactor control actions, equipment operation, and system adjustments.
• Monitor reactor parameters, facility instrumentation, and control panels to ensure safe, stable, and compliant operation during commissioning, startup, testing, and steady‑state operations.
• Conduct routine equipment checks, operational tests, surveillances, and field walkdowns to verify system readiness and identify abnormal conditions.
• Maintain accurate logs, operational records, and shift documentation in accordance with regulatory and organizational requirements.
• Respond to alarms, transient conditions, and abnormal events by executing required immediate actions and applicable emergency or abnormal operating procedures.
• Perform hands‑on maintenance activities, including basic mechanical or electrical tasks within qualification boundaries, and support maintenance teams during troubleshooting and repairs.
• Support commissioning and initial startup testing by performing operational evolutions, assisting with procedure validation, and verifying system performance.
• Ensure strict adherence to conduct‑of‑operations principles, radiation protection practices, contamination control measures, and industrial safety requirements.
• Collaborate with engineering, maintenance, and operations personnel to resolve equipment issues and support corrective actions.
• Participate in training, drills, and qualification programs to maintain operational proficiency and support continuous improvement within the operations team.

• Must have a High School Diploma or successfully passed the General Education Development (GED) test.
• For SROs candidates: 3 years of nuclear operations experience is required. On a case‑by‑case basis, formal education (i.e., baccalaureate degree or higher) may be used to substitute part of the experience requirements. Experience acquired at nuclear power, test and research reactors count toward nuclear experience.

• Strong preference for candidates to hold or have previously…
