Full job description

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

Requirements

Essential:

PhD in plasma physics or related discipline (or equivalent experience)
Understanding of tokamak physics, particularly plasma exhaust and core-edge integration
Experience in experimental data analysis and uncertainty handling
Programming skills (e.g. Python, scientific computing, version control)
Strong communication skills and ability to work collaboratively
Able to manage multiple priorities in a fast-paced environment

Desirable:

Experience in edge, SOL, or divertor physics
Exposure to tokamak operations and experimental planning
Experience with scientific modelling tools (e.g. SOLPS-ITER, TRANSP, EFIT, COMSOL, ANSYS)
Familiarity with databases and data systems
Experience in cross-functional or matrix environments

Personal Attributes

Adaptable and flexible, thriving in a scale-up environment
Curious and eager to develop new skills
Proactive, self-motivated, and comfortable taking ownership

Health & Safety Requirements
This role includes activities requiring occupational health clearance, such as:

Driving on company business
Working near high magnetic field equipment
Occasional international trave

Benefits

Competitive salary tailored to your skills and experience (openly discussed from the outset)
25 days holiday + bank holidays, plus discretionary festive shutdown
Performance-led rewards including bonus, innovation and merit schemes
Share options – a stake in our future success
Pension and comprehensive financial protection package
Health and wellbeing support, including cash plan and 24/7 assistance
Ongoing investment in your growth with training and career progression
Be part of world-changing innovation in fusion energy
