Hot Cell Design Engineer

Thanks for your interest in Oklo! We are searching for a radiological Hot Cell Design Engineer to join our dynamic fuel recycling engineering group, which is designing and deploying a modern nuclear fuel recycling facility. This is a rare opportunity to contribute to the design and development of one of the most advanced radiological hot cell systems ever. Position Description: As a Hot Cell Design Engineer at Oklo, you will help shape a highly specialized, remotely-operable hot cell environment that enables the safe, efficient processing of used nuclear fuel (UNF). You’ll work collaboratively with a multidisciplinary team of mechanical, nuclear, chemical, and controls engineers to integrate critical systems such as shielding, containment, and remote operations into an industrial-scale recycling facility. Key Responsibilities: Lead or support the mechanical and systems design of radiological hot cells used in UNF recycling, including shielding, ventilation, confinement, and remote handling systems Define equipment and material layouts, including material transfer pathways and maintenance access strategies Work with radiation modeling and safety analysis specialists to develop shielding requirements and establish design constraints Integrate robotic and remote handling technologies (e.g., manipulators, cameras, cranes, etc.) into cell design Contribute to the structural evaluation of confinement systems, ensuring compliance with fire protection, external hazard, and natural phenomena hazard requirements Collaborate with structural, HVAC, instrumentation, and process engineers to ensure seamless integration across all hot cell systems Participate in Failure Modes and Effects Analyses (FMEA), hazard analyses, and radiological safety assessments Contribute to design reviews, procurement specifications, and installation and commissioning plans Support prototyping, testing, and commissioning of hot cell subsystems Competencies: We are looking for a Hot Cell Design Engineer that is: Passionate about clean energy, fuel recycling, and efficient stewardship of natural resources An optimist at heart Passionate about making advanced fission a reality Willing and able to learn quickly Willing to think differently and do things in new ways Comfortable in a fast-paced, highly-iterative startup environment Excited to think creatively, critically, and reflectively about the problems they are solving while not leaning only on what has been done before Willing to propose novel and creative solutions to technical problems An excellent writer who can write in a modern active voice (so make your cover letter compelling and write it well!) Able to communicate technical content and results verbally Minimum Qualifications: Bachelor’s degree or higher in Mechanical Engineering, Nuclear Engineering, or a related discipline 5+ years of experience in radiological facility design, glovebox or hot cell engineering,…
