We are looking for:
A skilled, enthusiastic and experienced scientist who is interested in theory, simulation and modelling techniques related to high-energy-density physics to join our Physics Assurance and Validation team. You will have a developed appreciation and practical skills in the theoretical and simulation basis of the plasma physics related to inertial fusion energy (IFE) systems, particularly relating to hot electron generation and propagation during intense laser-matter interaction and the equation of state, transport and relaxation properties of dense, interacting systems. You will be a confident user of multi-physics codes to examine and understand integrated problems, have a working appreciation of verification, validation and cross-code comparison, and have experience running a variety of simulation codes for generating the data needed to provide assurance for First Light Fusion’s numerical modelling capabilities. You will also be aware of the role of modern AI and machine learning techniques in code acceleration, nonlinear regression problems and model uncertainty quantification.
Role responsibilities
- Understanding, reproducing and developing models of constitutive physics at the cutting edge of IFE research.
- Carry out simulations and modelling to understand the impact of your work on systems of relevance, e.g., in-silico target design and experimental design and analysis.
- Enhance capability and assurance of our tools by implementing and designing new tests, modules and applications.
- Be prepared to work with colleagues across different teams on projects outside of your immediate experience and comfort zone.
- Provide technical input to colleagues in the application and interpretation of constitutive models and associated applied theory.
- Take ownership of defined technical tasks or work packages, delivering high-quality work to agreed timelines.
- Communicate and record your work in technical meetings, presentations, and written reports, occasionally including conference talks, posters, proceedings, and peer reviewed journal publications.
- Contribute to collaborations with external partners, academic groups, and research institutions where relevant.
