RF Physicist/Engineer

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 have an unrivalled track record designing and operating spherical tokamaks; the optimal route to commercial fusion energy. 

In addition to fusion energy, Tokamak Energy is recognised as the leader in High Temperature Superconductor (HTS) magnet, design, numerical modelling, and prototyping.  Our dedicated HTS magnet team, in collaboration with key manufacturing partners, is focussed on becoming the leading supplier of HTS magnets to multiple markets. 

The company, founded in 2009 as a spin-off from the UK’s Culham Centre for Fusion Energy, currently employs a growing team of over 250 people with experts from the UK and around the world.  It combines world leading scientific, engineering, industrial and commercial capabilities.  The company has 70 families of patent applications and has raised $250 million, comprising $200m from private investors and $50m from the UK and US governments.  Our US subsidiary, Tokamak Energy Inc, was established in 2019.

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 RF Heating and Current Drive team for a High-Power RF Physicist/Engineer with experience in maintenance and operation of high power (100 kW – 1 MW) RF systems. The successful candidate will work with fellow engineers and physicists on coordination of commissioning, operation, and future upgrades of new cutting-edge RF heating systems in the range of frequencies (80 – 170 GHz) which are currently in design and fabrication.

A key target is the development and implementation of multi-megawatt RF systems for heating of fusion plasma. This is an exciting opportunity to participate in a world leading development of fusion energy.
