About us

Fusion, the process that powers the sun and stars, is one of the most promising options for generating the cleaner, carbon-free energy that our world badly needs. UKAEA leads the way in realizing fusion energy, partnering with industry and research organisations to achieve ground-breaking advancements. Our goal is to bring fusion electricity to the grid by developing the power stations of tomorrow and the skilled workforce to deliver them. 

Join UKAEA's Computing team and play a key role in developing and supporting the software systems that underpin world-leading fusion research. Working closely with scientists and engineers, you will design, build and maintain research data platforms and tools that enable users to store, access, analyse and visualise complex scientific data. This is an opportunity to work on technically challenging problems in a collaborative environment while contributing directly to the future of fusion energy.

As a Software Engineer, you'll take ownership of software systems in operational use, contribute to the full software development lifecycle, and help drive improvements in software engineering and data management practices across the organisation.
