Tokamak Scenario Modeller

Location: Milton Park, Abingdon, Oxfordshire
Job type: Full Time, Permanent

The role

Are you passionate about accelerating the development of fusion power? If so, Tokamak Energy are seeking talented and innovative individuals to join their physics team and help make limitless fusion energy a reality.

Tokamak Energy’s mission is to transform the way the world generates power by creating a clean, safe and sustainable source of energy for current and future generations. Our innovative approach to fusion is based on two emerging technologies: spherical tokamaks (STs) and high-field magnets made from high temperature superconductors (HTS).

Combining these two technologies enables efficient fusion power production in devices much smaller than previously thought possible. To demonstrate this revolutionary technology, Tokamak Energy are currently operating the worlds first high field spherical tokamak, ST40; designing and building increasingly powerful high-field HTS magnets; and designing a large scale HTS tokamak, ST-F1, that will be the first device to demonstrate the viability of fusion power.

Tokamak Energy are looking for a physicist to develop and optimise tokamak operating scenarios that take full advantage of the beneficial properties of high field spherical tokamaks.

This role will include:

  • modelling and optimising tokamak operating scenarios
  • developing fully non-inductive scenarios with high bootstrap fractions and electron cyclotron (EC) heating
  • exploring novel plasma start-up schemes
  • modelling for both ST40 and future devices
  • working closely with Tokamak Energy’s collaborators to improve modelling capabilities
  • incorporating the latest results and understanding from relevant experiments


Essential selection criteria

  • PhD in plasma physics or closely related equivalent experience
  • Experience working in a research environment or developing novel technologies
  • Ability to work efficiently on own initiative
  • Highly motivated to deliver against challenging objectives in a compressed timescale
  • Ability to contribute effectively in a multi-disciplinary team of engineers and scientists
  • Willingness to learn and adopt new techniques and technologies
  • Ability to effectively communicate results to both technical and non-technical colleagues
  • Organised approach to tackling complex problems


Desirable selection Criteria

  • Familiarity with tokamak/plasma modelling codes
  • Experience of programming languages such as MatLab/Python/Unix/C++
  • Experimental data analysis experience
  • Publication history
  • Willingness to develop new and existing collaborations



  • 25 days holiday (plus bank holidays)
  • Company pension scheme
  • Eligible for company share option scheme after 1 years’ service
  • Company bonus scheme, discretionary, dependant on performance
  • Private medical insurance after 3 months service
