Reactor Core Thermal Fluids Engineer

<p data-renderer-start-pos="6019">Thanks for your interest in Oklo!  We are searching for a Thermal Fluids Engineer to join our Core Thermal-Hydraulics team. </p> <p data-renderer-start-pos="6130"><strong data-renderer-mark="true">Position Description</strong></p> <p>The Core Thermal-Hydraulics team at Oklo is responsible for analyzing fluid flow and heat transfer within a reactor core. The work includes engineering analyses of thermal-fluid dynamics, clear and thorough documentation of the analyses, as well as interfacing with design teams. A engineer on the team will contribute to the development, qualification, and validation of methods for modeling coolant flow within reactor cores using one-dimensional models, intermediate-fidelity subchannel models, and high-fidelity computational fluid dynamics models.</p> <p data-renderer-start-pos="6682"><strong data-renderer-mark="true">Specific responsibilities may include:</strong></p> <ul> <li>Modeling core thermal-hydraulic behavior using</li> <ul> <li>subchannel codes such as DASSH, MOOSE-Subchannel, or COBRA-TF</li> <li>one-dimensional systems codes such as SAS4A/SASSYS-1 or RELAP</li> <li>first principles approaches and in-house flow network models</li> <li>3-D computational fluid dynamics</li> </ul> <li>Developing and documenting methods to analyze core thermal-hydraulic behavior at steady-state and during transients</li> <li>Automation, verification, and validation of modeling and simulation tools in support of analyses</li> <li>Collaborating cross-functionally to define design requirements, and providing technical feedback to quick-iterating design teams</li> </ul> <p data-renderer-start-pos="8245"><strong data-renderer-mark="true">Minimum Qualifications</strong></p> <ul> <li>Bachelors, Masters, or PhD in a technical field, such as nuclear, mechanical, or aerospace engineering</li> <li>Proficiency with thermal fluids (thermal-hydraulics) analysis methods and first principles</li> <li>Able to write clear and concise documentation</li> <li>Experience with <ul> <li>low-fidelity and intermediate-fidelity (e.g., porous body and correlation-based) models for heat transfer and fluid flow</li> <li>numerical methods and software development for heat transfer and fluid flow problems</li> <li>data processing (e.g., pre-processing, post-processing, scripting)</li> </ul> </li> </ul> <p data-renderer-start-pos="8245"><strong data-renderer-mark="true">Bonus Qualifications</strong></p> <ul> <li>Fluency with Python</li> <li>Demonstrated su
