Job Description
About us
Fusion, the process that powers the sun and stars, is one of the most promising options for generating the cleaner, carbon-free energy that our world badly needs. UKAEA leads the way in realizing fusion energy, partnering with industry and research organisations to achieve ground-breaking advancements. Our goal is to bring fusion electricity to the grid by developing the power stations of tomorrow and the skilled workforce to deliver them.
About the job
The Computational Materials and Engineering (CME) Unit within UKAEA’s Computing Division delivers research, development and technical support across high-performance computing, engineering and scientific computing, AI, machine learning and advanced simulation technologies for the fusion programme. In this role, you will lead the development and maintenance of software capabilities supporting computational nuclear and multiphysics applications, while driving research, collaboration, funding and adoption of emerging technologies. You will provide technical and strategic leadership, manage projects and resources, represent UKAEA nationally and internationally, and help shape future research directions while developing expertise and collaborations across the Authority.
What You’ll Be Doing
General:
- Lead research and development activities, driving novel numerical techniques, advanced simulation and modelling approaches, and the development of world-leading codes for fusion applications and beyond.
- Lead and develop research teams, managing small to medium-sized teams of 4–10 people across multiple concurrent projects, while building expertise and capability around your research area.
- Drive research, funding and collaboration opportunities, establishing new partnerships with industry, academia and across UKAEA, and actively identifying opportunities for future research and funding.
- Collaborate and represent UKAEA nationally and internationally, contributing to expert and working groups and working with partners to develop and evolve codes for peta- and exa-scale computing systems.
- Share expertise and research outputs, contributing to peer-reviewed publications, supporting other UKAEA units where required, and planning and leading simulation and modelling activities across relevant UKAEA programmes.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you

Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll Bring
Experience:
- At least a doctorate degree in a computational, mathematical or physical science discipline or a leadership role in either a commercial or research environment in one of these fields.
- An international reputation in your field gained in either a research or commercial environment.
- Demonstrable experience of at least one compiled level language (e.g. C++, Fortran, C, Rust) and advanced scripting language (e.g. Julia, Python), preferably in a UNIX environment.
- Experience of agile project and budget management in a team leadership role.
Specific Experience:
- Solid foundation in mathematics, especially numerical analysis, demonstrated by either a publication record or contribution to a relevant software library.
- Significant and demonstrable experience in parallel programming techniques (e.g. MPI, OpenMP and accelerator hardware such as GPUs).
- Experience leading a distributed team in both mentoring and managing roles.
- Experience of the development and implementation of testing strategies (verification and validation) and an ability to assess new algorithms which could be applicable to fusion based codes.
- Significant experience in at least CFD and ideally more relevant nuclear and multiphysics fields (e.g. FV, FD, FE, MHD, Monte Carlo, and associated workflow).
- A good background in Uncertainty Quantification and actionable data.
