Senior Computational Fluid Dynamics Engineer

Thanks for your interest in Oklo! We are searching for a  Senior Computational Fluid Dynamics (CFD) Thermal-Hydraulics Engineer to join our team. Position Description The thermal-hydraulics group at Oklo is 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 CFD Engineer in this group will be responsible for conducting high-fidelity thermal fluid simulations using commercial CFD tools. Level (Engineer III/Senior) will be determined by experience. Specific responsibilities may include: - Developing and conducting high-fidelity analyses using CFD to analyze thermal-hydraulic behavior through the reactor core, reactor vessel, heat exchangers, power conversion, and balance of plant systems - Proactively designing, modeling, and analyzing thermal hydraulic systemsDeveloping and utilizing analysis methods that efficiently and effectively build confidence in a design - Performing engineering analyses, which can include thermal, fluid, safety, manufacturability, and cost - Collaborating cross-functionally to define design requirements, and providing technical feedback to quick-iterating design teams - Documenting work using modern tools and techniques, and writing well-written, thoughtful technical reports - Providing technical feedback to quick-iterating design teams Minimum Qualifications - Bachelors, Masters, or PhD in a technical field, such as nuclear, mechanical, or aerospace engineering - Proficiency with STAR-CCM+, ANSYS Fluent, OpenFOAM, Nek-5000, or equivalent - Core competencies in heat transfer, fluid dynamics, and thermodynamics first principles  - Experience with data processing (e. g.

, pre-processing, post-processing, scripting) Bonus Qualifications - Experience with thermal hydraulic engineering principles and multi-physics analysis methods for engineering applications, particularly as they relate to power systems - Experience with nuclear engineering principles and multi-physics analysis methods for engineering applications, particularly as they relate to advanced reactors - Experience with analysis of heat exchangers, turbomachinery, and fluid control systems - Competency with modern software engineering practices and programming languages - Fluency with Python - Experience with reactor transient analysis methods - Experience with systems or reactor safety codes such as GOTHIC, RELAP, TRACE, SAM, or SAS4A/SASSYS-1 - 5 years or more CFD experience in an industrial setting Competencies: We are looking for a Senior CFD Thermal-Hydraulics Engineer that is: - Passionate about clean energy - Passionate about making advanced fission a reality - Willing and able to learn quickly - Skilled with CFD tools such as STAR CCM+, Fluent, or similar - Experienced with thermal fluids analysis - Eager to work on a dynamic team, receive constructive feedback, and grow with us - Comfortable in a fast-paced, highly iterative environment - Excited to think creatively, critically, and reflectively about the problems they are solving, while not leaning only on what has been done before  - Excellent communicator of technical content both verbally and in writing Who you are: A startup person: You aren't driven by titles or hierarchy, and prefer efficiency to excess process. You don't need or expect to have a lot of guidance but you enjoy working in a fast-paced team. If you prefer the culture and feel of a large organization, that is great, but you likely won’t enjoy working with us! There is plenty of important work and plenty of good opportunities with organizations like that. Motivated: You are self-motivated. You bring an enthusiasm to the team, and imbue a sense of passion that goes beyond clocking in and clocking out. This isn’t about a fake or arbitrary “pieces of flair” mentality or lack of work-life balance!
