Neutronics Analysis Engineer

Overview Thanks for your interest in Oklo! We are searching for a Neutronics Analysis Engineer to work with our engineering team and help us wrangle the neutrons. Position Description The Neutronics Analysis Engineer is responsible for defining, developing, and executing in-core and ex-core neutronics analyses to support reactor design, performance evaluation, and safety assurance. This role involves working closely with the broader design team to solicit and capture requirements, establish the scope of neutronic evaluations, and implement appropriate models and methods. Areas of analysis include, but are not limited to, criticality, depletion, activation, and shielding. The engineer will also support verification and validation activities and contribute to licensing and regulatory interactions by providing technically sound and defensible neutronics analyses. Specific responsibilities Perform the complete range of actions involved in supporting core design and fuel cycle analysis using Monte Carlo and deterministic codes on Oklo reactors. Perform calculations and analyses in Monte Carlo based codes such as Serpent, MCNP, SCALE, and OpenMC. Perform calculations and analyses with fast reactor deterministic codes such as DIF3D, PERSENT. Support the qualification and verification of neutronic analyses, including validation against experiments and benchmarks. Be aware of and familiar with fast reactor core design and analysis work being performed internationally, as well as related benchmark calculations and experiments being performed internationally Provide technical feedback to quick-iterating design teams. Document work using modern tools and techniques, and write well-written, thoughtful technical reports. Who you are We are looking for a neutronics engineer that is: Passionate about clean energy Passionate about making advanced fission a reality Willing and able to learn quickly Highly skilled with Monte Carlo neutronics tools such as SERPENT, MCNP, SCALE and Open-MC Skilled with deterministic fast reactor tools, or willing and eager to learn Eager to work on a dynamic team, receive constructive feedback, and grow with us 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 modern active voice, so make your cover letter compelling and write it well! Able to communicate technical content and results verbally Minimum Qualifications If you have experience and expertise in reactor design, apply! We also think the following are good indicators of qualifications to do this job: Bachelors, Masters, or PhD in a technical field, such as nuclear engineering, with experience in reactor design and analysis (Masters or PhD may be preferable) Fluency with Python Experience with modern object oriented languages, preferably C++ Proficiency with high performance computing systems Experience with fast reactor design and analysis is highly recommended Proficiency with MCNP and SERPENT is highly recommended Proficiency with ORNL’s SCALE code system (TRITON, KENO, SAMPLER, etc.) is recommended Proficiency with Argonne\'s ARC codes (MC2, DIF3D, etc.) is recommended Salary may fall outside of the range provided and will be dependent on applicant experience. Oklo offers untracked paid time off, competitive pay, equity, 401k, health insurance, FSA, flexible work hours, and other benefits. We are looking to fill this position immediately! About Oklo Oklo Inc. is developing fast fission power plants to deliver clean, reliable, and affordable energy at scale; establishing a domestic supply chain for critical radioisotopes; and advancing nuclear fuel recycling to convert nuclear waste into clean energy. Oklo was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant, was awarded fuel material from Idaho National Laboratory, and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission. Oklo is also developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and U.S. National Laboratories. Apply for this job Oklo requires employees to travel based on team/company needs. Travel expectations and relocation options will be discussed during the interview process. #J-18808-Ljbffr Oklo
