Mechanical Engineer (Magnets)

The Tokamak Energy Mechanical Engineer supports the development of high temperature superconducting (HTS) magnet technologies used in advanced fusion energy systems and other cutting-edge applications. The role focuses on the mechanical and structural design, analysis and development of superconducting magnets, working on engineering challenges involving structural modelling, material behaviour, thermal performance and the mechanical integrity of magnet systems. Tokamak Energy is looking for candidates with a background in finite element analysis and structural simulation using tools such as ANSYS Mechanical and ANSYS Workbench, and the listing is clear that this is not primarily an electromagnetic modelling role.

The Tokamak Energy Mechanical Engineer joins a company that is a global leader in fusion energy and HTS technologies, with end-to-end capability in HTS systems from design to manufacturing. Tokamak Energy is 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. Founded in 2009 as a spin-out from the UK Atomic Energy Authority, it is headquartered in Oxfordshire, employs over 300 people and has secured more than £280 million in investment.

Key Responsibilities

• Develop mechanical and structural designs for HTS magnet systems
• Build, validate and improve detailed finite element models using ANSYS Mechanical and ANSYS Workbench
• Analyse stresses, strains, thermal effects and structural performance of complex magnet assemblies
• Own the mechanical development of magnet designs from concept through testing and validation
• Maintain and develop the mechanical materials database, ensuring appropriate material models are used within simulations
• Work closely with test engineers to correlate physical test data with simulation results
• Produce clear technical reports and recommendations based on modelling and experimental findings
• Collaborate with multidisciplinary engineering teams to support programme delivery and technology development
• Support prototyping, testing and commercialisation activities

Requirements

Essential:

• Degree in mechanical engineering or a closely related engineering discipline
• Strong experience in structural analysis and finite element modelling
• Advanced knowledge of ANSYS Mechanical and ANSYS Workbench
• Experience analysing complex mechanical systems and structures
• Understanding of material properties, structural behaviour and engineering validation methods
• Ability to interpret test results and correlate them with simulation outputs
• Experience working within multidisciplinary engineering environments

Desirable:

• Experience of superconducting magnets, cryogenic systems or high-field technologies
• Experience using MATLAB or Python
• Experience within fusion, aerospace, energy, scientific research or other high-technology sectors
• Familiarity with COMSOL or coupled multiphysics environments

Appointment is subject to standard pre-employment screening, including right-to-work, proof of identity and references.
