Job Description

First Light Fusion is actively developing an experiment to reach gain from an inertial confinement fusion target in the UK. To help us in this effort, we are looking for a skilled and
experienced scientist to help us to develop our target designs.

In this role, you will work with a small team to develop our current target designs and invent
new ones. You will have a high degree of autonomy to pursue your own ideas and
approaches. First Light Fusion operates with its own experimental and manufacturing facilities,
enabling us to move quickly and innovate. This will allow your ideas to progress from a basic
concept to a working experiment over a short period of time. To facilitate this, you will
collaborate across the technical team, using your expertise to ensure that targets are
designed, manufactured, and fielded on experiments in a way that maximises performance.
You will also act as a source of knowledge and experience, that other scientists within the
company can draw on when pursuing their own ideas.

The position is available at either Senior or Lead Scientist level, depending on knowledge and
related experience.

Responsibilities will include

  • Develop new inertial fusion schemes from basic theory.
  • Use our in-house hydrodynamic and magneto-hydrodynamic codes to invent new targets and develop current ones, aiming to achieve the highest possible fusion yields from First Light Fusion’s driver machines.
  • Run simulations to understand in depth the dynamics and physical processes at work within our targets.
  • Use Python and other tools to analyse results and identify trends.
  • Provide specialist technical support and training, aiding other scientists at First Light to develop their own target designs and interpret their results.


  • PhD in a STEM subject, or equivalent industry experience.
  • Comprehensive knowledge of high energy shock physics or inertial fusion physics.
  • Proven track record of using simulation tools to design and develop complex,
    multiphysics based systems.
  • Ability to work effectively as part of a multidisciplinary team.
  • Strong communication and interpersonal skills.
  • Good programming skills.


  • Experience developing fusion target designs for experiments
    on international facilities.
  • Knowledge of software engineering good practice.
  • Understanding of the numerical methods used in hydrodynamics codes.
  • Experience with machine learning and other advanced optimisation methods.
  • Programming experience in Python, C++ or Fortran.
