Company Description

By 2050, the planet could be using twice as much electricity compared to today. Are you interested in contributing and helping to shape the future of the world’s energy? If so, read on.

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 realising fusion energy, partnering with industry and research for ground-breaking advancements. Our goal is to bring fusion electricity to the grid, supported by tomorrow's power stations. In pursuit of our mission, UKAEA embraces core values: Innovative, Committed, Trusted, and Collaborative.

As an employee of UKAEA, you will benefit from:

- Outstanding defined benefit pension scheme, details of which can be found at the end of this advert.

- Corporate bonus scheme up to 7% and a Relocation allowance (if eligible).

- Flexible working options including family friendly policies and the right to request flexible working from the start of your employment.

- Employee Assistance Programme and trained Mental Health First Aiders.

- Generous annual leave allowance starting with 25 days, plus 3 days Christmas closure and 2.5 privilege days, in addition to UK bank holidays.

- Wide range of career development opportunities.

- A vibrant culture committed to equality and being fully inclusive.

Job Description

The salary for this role is £40,609 (inclusive of a Specialist Allowance). Onsite working is expected for 2-3 days a week, however, we actively support requests for flexible working.

As an HPC Computational Engineer, you will join the Advanced Engineering Simulation Group within the UKAEA’s Computing Division. We conduct research and development across diverse areas such as high-performance computing, algorithm development, artificial intelligence, and machine learning. Our focus is on optimising research workflows and advancing computing infrastructures for fusion reactor engineering. We collaborate with academia and industry on novel computing technologies and algorithms. Join us to contribute to UKAEA's mission through impactful projects and engagement with users and stakeholders.

Key Accountabilities:

- Contribute to modelling, simulation and uncertainty quantification activities for UKAEA fusion programmes such as the LIBRTI (Lithium Breeding Tritium Innovation) Programme.

- Development, testing and maintenance of performant and highly scalable codes.

- Data preparation and analysis from either experimental devices or simulations.

- Development of high-fidelity integrated multi-physics models of fusion systems (digital twins).

- Deployment and migration of codes to new computing architectures.

Other Duties:

- Promote and disseminate our activities both internally and externally through reports, journal articles, conference contributions, and published software packages.

- Willingness to travel domestically and abroad for short periods.
