Innovative Shielding & Radiation Transport Engineer

Oklo Inc; Santa Clara (CA); On-site; USD 102,000 - 225,000; Full time

Job summary

Oklo Inc. is seeking an Shielding Analysis Engineer to define, develop, and execute radiation shielding analyses to support reactor design, plant layout, and safety assurance.

You will work with the design team to establish scope, develop source terms, activation, dose assessments and shielding optimization. The role requires expertise in Monte Carlo methods, radiation transport tools (MCNP, SCALE, OpenMC, Serpent) and variance reduction techniques, with a strong emphasis on rigorous

Qualifications

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

Responsibilities

• Perform the complete range of actions involved in supporting shielding design, radiation transport analysis and dose assessment using Monte Carlo and supporting codes on Oklo facilities.
• Perform calculations and analyses in Monte Carlo based radiation transport codes such as MCNP, SCALE, OpenMC and Serpent.
• Conduct source‑term, activation, streaming, skyshine and dose‑rate analyses using appropriate Monte Carlo and deterministic methods.
• Support the qualification and verification of shielding analyses, including validation against experiments, benchmarks and operationally relevant radiation measurements.
• Be aware of and familiar with radiation shielding, radiation transport and fast‑reactor core design and analysis work performed internationally, as well as related benchmark calculations and experiments.
• Provide technical feedback to next‑iterating design teams.
• Document work using modern tools and techniques, and write well‑written, thoughtful technical reports.
