Scientist (Numerical Physics)

The successful candidate(s) will bring their experience of physics, simulations and computational methods to the numerical tools underpinning First Light’s approach. We are looking for someone with a strong foundational understanding of numerical physics approaches, to build on and apply that knowledge to solve previously unseen challenges.

Our primary numerical physics capability is an adaptive front-tracking hydro-code, with coupled conduction, radiation and microphysics models. The code is core to the business plan and a very important company asset. The successful candidate(s) will contribute to the development of this code, as well as adding further physics such as MHD.  It is also expected that you will work closely with the in-house experimental team to provide simulation support and perform code validation.

The team takes an agile approach using the Atlassian toolset.



  • Degree in physics or related field
  • Comprehensive knowledge of physics
  • Experience in computational modelling of complex systems, particularly simulations solving plasma physics equations or hydrodynamic equations
  • Passion for fusion and for taking a bold approach to a high-risk transformational technology
  • Demonstrated self-motivation, enthusiasm to work in a dynamic team environment and evidence of taking the initiative
  • Strong communication and interpersonal skills


  • Working knowledge of numerical methods for solving hyperbolic and parabolic PDEs
  • Experience with interface tracking methods and multiphase-flows
  • Knowledge of shock physics or hydrodynamics
  • Experience with C++, Python and object-oriented programming
  • PhD or equivalent experience in a relevant field
