Are you ready to help shape the future of clean energy?
We're working with a world-renowned organisation at the forefront of fusion energy development - and they're looking for a Senior Thermal Hydraulic Analyst to join their multidisciplinary engineering team. This is a rare opportunity to apply your simulation expertise to some of the most complex and advanced design challenges in the energy sector.
?? The Role
As a Senior Thermal Hydraulic Analyst, you'll provide critical technical input in computational thermal hydraulics and heat transfer analysis. You'll play a key role in assessing and optimising high-performance fusion components using simulation tools like Ansys Fluent and Workbench.
This is a technically rich role, where your modelling insights directly influence the design of next-gen nuclear systems.
?? What You'll Be Doing:
* Developing and applying advanced CFD and FEA models to simulate component performance under extreme thermal and fluid dynamic conditions.
* Building and refining complex 3D geometries, conducting mesh independence studies, and applying parameterisation techniques for robust design evaluation.
* Leveraging expert knowledge in turbulence, conduction, convection, and radiation to critically evaluate results and inform design decisions.
* Validating CFD outcomes with analytical and semi-analytical models, including 1D/2D methods.
* Contributing to technical documentation, peer reviews, and external publications.
* Promoting a strong safety culture and collaborating across a cross-functional R&D environment.
?? What You'll Need:
* A degree in a STEM discipline or equivalent experience in a research-led environment.
* Proven background in thermal hydraulics and heat transfer simulations within a research or advanced engineering setting.
* Proficiency in CFD (especially Ansys Fluent/Workbench), meshing complex 3D geometries, and applying mesh refinement techniques.
* Strong understanding of turbulence modelling and first-principles analytical methods.
* Confident communicator with a detail-oriented mindset and strong problem-solving capabilities.
?? Bonus Points For:
* Experience with OpenFOAM or other major CFD software.
* Familiarity with 1D network simulation tools such as Flomaster or OpenModelica.
?? Why Join?
This is your chance to be part of one of the most ambitious and meaningful engineering missions on the planet. You'll work in a highly collaborative environment with cutting-edge simulation tools and contribute to real-world innovations in fusion energy - a field with the potential to revolutionise global energy systems.
