Engineering Analyst - CFD/MHDTokamak Energy

Abingdon, England, United Kingdom 28-04-2023
Open Source


Company Background

What if there was a limitless, safe, clean, low-cost energy source, providing much needed global energy security? What if that energy source could also help reduce climate change? We believe that’s fusion energy. Tokamak Energy is a leading global commercial fusion energy company based near Oxford, UK. We are taking established science and building on it by pioneering the use of spherical tokamaks in conjunction with high temperature superconducting magnets.

The company, founded in 2009 as a spin-off from the Culham Centre for Fusion Energy, currently employs a growing team of over 180 people with talent from the UK and around the world including expert scientific, engineering, industrial and commercial capabilities. The company has more than 55 families of patent applications and has raised over £100m of private investment.

Once realised, fusion energy will be a key enabler for meeting world energy requirements and climate policy goals. Come and be a part of a dynamic and innovative team who are striving to provide a solution to one of humanity’s greatest challenges: clean and sustainable energy for all.

Overview of the role

A position is available in the Divertor team for a Development Engineer. The successful candidate will be responsible for the integrated analysis workflow of divertor systems and other plasma-facing components. This includes novel materials and coolants for in-vessel tokamak components for present and future fusion devices at Tokamak Energy. The candidate will have a methodical but practical mindset, capable of evaluating and selecting emerging technologies through advanced analysis techniques, able to understand and validate to experimental data; organised, self-driven and able to work to defined timescales.

In this role, you will:

  • Deliver analysis in line with the divertor development plan related to the design, experimental validation, Physics integration and testing activities.
  • Define and analyse relevant testing activities in coordination with tokamak physics and engineering designers, as required for the next generation of fusion devices.
  • Collaborate in the assessment and qualification of the performance of plasma-facing components to be installed inside the tokamak vacuum enclosure using molecular and viscous flow analysis techniques.
  • Participate in the design of novel liquid metal tokamak components, monitoring internal and external analysis and qualification, both in laboratory and during tokamak operations.
  • Manage analysis and assessment interfaces, liaising with physicists and engineers responsible for other tokamak systems’ R&D, power supplies, HTS magnet design and overall integration.
  • Monitor external development on novel techniques for improving pumping and heat flux handling performance in solids and liquid metals.
  • Liaising with external contractors and researchers for the supply of technology development solutions.
  • Plan and organize dedicated experiments, measurements, and test-rigs for PFC development, in coordination with ST40 and Divertor Laboratory managers.
  • Specification and design of parts and assemblies required for setting up dedicated testing.
  • Highly motivated to deliver against challenging objectives in a compressed timescale.
