Senior Process Equipment Engineer - Fuel Recycling

Thanks for your interest in Oklo! We are searching for a Senior Process Equipment Engineer to join our Fuel Recycling engineering team. Position Description The person in this role will lead the engineering development of process equipment and integrated process systems supporting Oklo's advanced fuel recycling facility. This role bridges process engineering, mechanical design, equipment vendors, pilot testing, and facility integration as the project advances from conceptual design through preliminary engineering and into detailed design.

The engineer will work closely with subsystem technical leads responsible for off-gas treatment, pyroprocessing, waste management, process safety, and facility engineering to mature first-of-a-kind process equipment into construction-ready designs. This individual will become the responsible engineer for equipment realization rather than process invention. Specific responsibilities may include: - Lead development of process equipment from conceptual design through IFC packages - Develop equipment specifications, data sheets, and procurement documentation - Own equipment sizing and mechanical/process interfaces for vessels, heat exchangers, filters, adsorption systems, blowers, compressors, pumps, piping systems, and specialty process equipmentPerform process calculations supporting equipment selection - Develop utility requirements and equipment operating envelopes - Work with equipment vendors to develop custom first-of-a-kind equipment - Evaluate vendor proposals and participate in technical bid evaluations - Support PFD, P&ID, process narrative, equipment list, line list, and instrument list development - Develop process design criteria and engineering calculations - Support HAZOPs, design reviews, and safety analyses - Support process startup planning and commissioning activities - Develop acceptance testing procedures (FAT/SAT) - Coordinate closely with facility engineering, mechanical engineering, I&C, nuclear safety, and licensing teams - Participate in pilot plant planning and interpretation of pilot data - Travel periodically to vendors, national laboratories, pilot facilities, and project partners Minimum Qualifications: - Degree in chemical engineering, mechanical engineering or related field - 8+ years of process engineering experience - Experience developing process equipment - Experience producing engineering calculations - Experience with Aspen Plus, HYSYS, ChemCAD, or similar - Experience with industrial gas processing, chemical processing, or separations Bonus Qualifications: - Experience deploying or working on pilot plants and scaling from demonstration to industrial scale at brown/green field sites - Commercial or nuclear industry experiences - Experience in adsorption systems, heat exchanger design, pressure vessel specification, compressor and blower selection - EPC experience, process equipment procurement and vendor management - FOAK technology commercialization Competencies We are looking for a Senior Process Equipment Engineer who is - Works effectively across multiple engineering disciplines and enjoys partnering with vendors, national laboratories, EPC contractors, and internal engineering teams - Comfortable developing engineering solutions where industry standards may not yet exist and enjoys applying first-principles engineering to novel problems - Passionate about clean energy - 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!
