Neutronics Analysis Engineer
The Neutronics Analysis Engineer at Oklo is responsible for defining, developing, and executing both in-core and ex-core neutronics analyses to support reactor design, performance evaluation, and safety assurance. This role involves close collaboration with the broader design team to gather requirements, establish the scope of neutronic evaluations, and implement appropriate models and methods. Areas of analysis include 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.
Key responsibilities include performing comprehensive core design and fuel cycle analyses using Monte Carlo and deterministic codes on Oklo reactors. The engineer will conduct calculations and analyses using Monte Carlo-based codes such as Serpent, MCNP, SCALE, and OpenMC, as well as fast reactor deterministic codes like DIF3D and PERSENT. Additional duties involve supporting the qualification and verification of neutronic analyses, including validation against experiments and benchmarks, staying informed about international fast reactor core design and analysis work, providing technical feedback to design teams, and documenting work through well-written technical reports.
The ideal candidate should possess a Bachelor's, Master's, or PhD in a technical field such as nuclear engineering, with experience in reactor design and analysis. Proficiency in Python and experience with modern object-oriented languages, preferably C++, are required. The candidate should have proficiency with high-performance computing systems and experience with fast reactor design and analysis is highly recommended. Proficiency with MCNP and SERPENT is highly recommended, while familiarity with ORNL’s SCALE code system (TRITON, KENO, SAMPLER, etc.) and Argonne's ARC codes (MC2, DIF3D, etc.) is recommended.
Oklo offers a competitive salary range of $102,000 to $225,000, depending on applicant experience. The company provides untracked paid time off, equity, 401(k), health insurance, flexible spending accounts (FSA), flexible work hours, and other benefits.
Oklo fosters a collaborative and innovative work environment, emphasizing values such as collaboration, humility, ownership, and pathfinding. The company encourages team members to think creatively and critically, proposing novel solutions to technical problems. Employees are expected to be self-motivated, detail-oriented, and comfortable in a fast-paced, highly iterative startup environment.
