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.
Overview
This is a hands-on, varied Electrical Technician role supporting a wide range of engineering, lab, and infrastructure activities in a dynamic technical environment.
You’ll work across multiple projects rather than a single production line, contributing to everything from control systems and power distribution to fault finding and installations. The role requires someone adaptable and practical, who can operate with minimal supervision and confidently tackle different challenges day to day.
This is ideal for someone who enjoys problem-solving, working across varied environments, and developing their skills in a broad electrical engineering setting.
Key Responsibilities
Assist with the design, layout, installation, and commissioning of control panels and control systems
Assemble, install, and maintain electrical systems, panels, and associated equipment
Carry out fault finding and troubleshooting on control systems, power supplies, and electrical infrastructure
Work on mains-powered systems, including distribution boards and final circuits
Install and maintain cable containment systems such as tray, conduit, and trunking
Install and support data networks and associated cabling and equipment
Perform testing and commissioning of electrical equipment and infrastructure
Respond to electrical breakdowns and emergency repairs
Collaborate with engineers, technicians, and contractors on larger-scale projects
Maintain safe working areas, identify risks, and ensure materials and tools are available when needed
What Makes This Role Different
Highly varied work — not a production-line or repetitive environment
Exposure to both control systems and mains electrical infrastructure
Practical, hands-on role across lab, workshop, and technical site environments
Opportunity to work on bespoke systems rather than standard installations
Involvement in projects that require problem-solving and adaptability day to day
Requirements
Essential Experience & Skills
Electrical apprenticeship or equivalent hands-on training and experience
Experience working safely with low voltage (LV) electrical systems
Ability to test, fault-find, and work confidently on electrical systems
Experience working with control systems, control panels, or similar electrical assemblies
Ability to read and work from electrical drawings and schematics
Solid understanding of health and safety principles when working with electrical systems
Comfortable working in a hands-on, practical environment (including varied physical tasks)
Proactive, self-motivated, and able to work with minimal supervision
Strong problem-solving…
