About The Position

Thermal-Hydraulics Engineers at Oklo are responsible for analyzing fluid flow and heat transfer within a reactor and associated systems. This work includes engineering analyses of thermal-fluid dynamics, clear and thorough documentation of the analyses, as well as interfacing with design teams. A Systems Thermal-Hydraulics Engineer will contribute to the development, qualification, and validation of systems-level models of steady-state and transient thermal-hydraulic reactor behavior.

Requirements

Bachelors, Masters, or PhD in a technical field, such as nuclear, mechanical, or aerospace engineering
Proficiency with thermal-hydraulics (thermal fluids) analysis methods
Core competencies in heat transfer, fluid dynamics, and thermodynamics first principles
Experience with systems-level thermal fluids analysis codes, such as Flomaster, GOTHIC, or TRACE
Experience with data processing (e.g., pre-processing, post-processing, scripting)
Fluency with Python

Nice To Haves

Experience with reactor transient analysis methods
Experience with advanced reactor systems codes such as SAS4A/SASSYS-1, SAM, and RELAP
Experience with qualification and validation of analyses
Experience with nuclear engineering principles and multi-physics analysis methods for engineering applications, particularly as they relate to advanced reactors
Competency with modern software engineering practices and programming languages
Experience with CI/CD computing environments

Responsibilities

Modeling thermal-hydraulic systems using codes such as SAS4A/SASSYS-1, SAM, or GOTHIC
Developing systems-level analyses to analyze coupled neutronic and thermal-hydraulic behavior at steady-state and during transients
Developing and utilizing analysis methods that efficiently and effectively build confidence in a design
Automation, verification, and validation of modeling and simulation tools in support of analyses
Collaborating cross-functionally to define design requirements, and providing technical feedback to quick-iterating design teams
Document work using modern tools and techniques, and write well-written, thoughtful technical reports
