Tokamak Energy aims to accelerate the adoption of fusion power generation by combining two emerging technologies - spherical tokamaks and high-temperature superconductors (HTS). The company is developing a series of technology demonstration prototypes, culminating in a pilot plant which will exceed fusion energy breakeven.

The successful candidate will be part of the HTS Engineering team, which is responsible for developing HTS technology for the plasma confinement magnets. Novel HTS technology is being developed in-house and demonstrated by manufacturing a series of prototype magnets of increasing scale. The successful candidate will play a key role in developing the cryogenic technology required to cool HTS coils to ~20K using helium cryo-circulation. The role involves taking ownership of the entire design process, from concept to testing prototype hardware, and represents a hugely exciting opportunity for an ambitious engineer.

Direct experience with design and/or development of cryogenic hardware, particularly in the fields of large-scale superconducting magnets (MRI, accelerators, etc), chemical engineering, oil and gas or process control is naturally a desirable attribute. However, HTS magnet technology for fusion applications generally requires a “clean-sheet” design approach. Therefore, we are interested to hear from creative engineers with an Engineering or Physics Degree and some experience working in an industrial/manufacturing R&D environment, who are interested in an exciting new challenge. Tokamak Energy has the in-house expertise to develop the skills of the right candidate.

Applicants must have a can-do attitude, ability to learn quickly, and be highly motivated by the opportunity to contribute to making fusion power a viable candidate as a global energy source on a sub-decade timescale.

Skills & experience

Duties will include

  • Design/specification, installation and commissioning of cryogenic systems for cooling prototype HTS magnets.
  • Liaising with other engineers responsible for HTS magnet design, tokamak physics, power supplies and mechanical integration.
  • Liaising with external contractors for supply of cryogenic hardware, ultimately leading to supply of the fusion magnet cryo-plant.
  • Internally the post holder will report to the HTS Technology Development Manager and liaise with the Electrical Engineering Group manager, Research Director and other mechanical, electrical and design engineers and working within the Company.
  • Externally the post holder will liaise with manufacturers, component suppliers and technical consultants in industry and academia.
  • The post will involve occasional travel within the UK and overseas.
