Job summary

Oklo Inc. in California seeks a Shielding Analysis Engineer to define, develop, and execute radiation shielding and transport analyses to support reactor design, plant layout, and safety assurance.

You will collaborate with the design team to establish scope and model source terms, activation, and dose-rate analyses using Monte Carlo and deterministic methods. The ideal candidate has strong Python, HPC, and radiation transport experience (MCNP, SCALE, OpenMC, Serpent) and a background in nuclear

Qualifications

• Bachelor’s/Master’s/PhD in a technical field such as nuclear engineering with experience in reactor design, radiation transport, shielding analysis, or radiation protection.
• Fluency with Python.
• Proficiency with high performance computing systems.
• Experience with fast reactor design, shielding design, or radiation protection analysis.
• Proficiency with radiation transport tools such as MCNP, SCALE, OpenMC, and Serpent.
• Knowledge of variance reduction techniques such as weight windows, surface read/write, source biasing, and CADIS/FW‑CADIS methods.
• Experience with source‑term generation, activation, dose‑rate calculations, and shielding design methods.
• Proficiency with CAD software such as SolidWorks (a plus).

Responsibilities

• Perform shielding design, radiation transport analysis, and dose assessment using Monte Carlo and supporting codes on Oklo facilities.
• Perform calculations using MCNP, SCALE, OpenMC, and Serpent.
• Perform source term, activation, streaming, skyshine, and dose-rate analyses using appropriate methods.
• Support qualification and verification of shielding analyses against experiments and measurements.
• Provide technical feedback to design teams.
• Document work and write technical reports.
