Tokamak Energy is a global leader in fusion energy and high temperature superconducting (HTS) technologies. We work with governments and industry to develop and bring fusion and HTS solutions to market through innovation and strategic partnerships. A major part of this is our end‑to‑end capability in HTS systems, from design to manufacturing.
We are the Magnet Systems Partner for the UK Government's STEP Fusion programme, under a £70 million contract running to 2029, working with UK Fusion Energy to deliver HTS magnet systems for the STEP prototype power plant, while also contributing to tokamak systems and plasma integration.
Founded in 2009 as a spin-out from the UK Atomic Energy Authority, Tokamak Energy is headquartered in Oxfordshire, with subsidiaries in the United States and Japan. Today, we employ over 300 people and have secured more than £280 million in investment.
We operate through three divisions:
Fusion - Fusion energy technologies, expertise and testbeds for government and private fusion programmes, including ST40, the world’s highest field spherical tokamak.
TE Magnetics - HTS systems for commercial applications including fusion energy, power distribution, life sciences, and propulsion.
Ridgway Machines - Manufacturing equipment for the superconducting, electrical and wider energy sectors, enabling the rapid industrialisation of HTS products.
The Opportunity
We are looking for a Plasma Physicist to join our Plasma Prediction & Simulation (PSPS) team, within the Integrated Core–Scrape-Off Layer (SOL)–Divertor group.
This is an exciting opportunity to work at the forefront of fusion research, supporting the ST40 LEAPS programme through experimental physics, data analysis, and modelling. You’ll contribute to high-impact projects, publications, and presentations, while collaborating with multidisciplinary teams across the organisation.
We welcome applications from early-career researchers through to experienced physicists.
Core Responsibilities:
- Support and perform edge and divertor physics experiments on ST40
- Analyse and interpret experimental data (e.g. Langmuir probes, IR thermography, spectroscopy)
- Apply computational modelling to support experimental findings
- Collaborate with cross-functional teams including Diagnostics, Data & Control
- Present insights internally and externally (conferences, publications)
Additional / Development Activities:
Predict heat flux on plasma-facing components using tools such as HEAT, COMSOL or ANSYS
- Support divertor and component design and optimisation
- Contribute to next-generation fusion device concepts
- Perform modelling relevant to edge and divertor physics
