HPC Computational Engineer

Overview of Responsibilities

Who are we looking for?

As an HPC Computational Engineer you will develop software solutions to address complex modelling challenges in the engineering of fusion reactors. You will interface with problem owners and through co-design you will create solutions which embrace scalability at its core. Your work will directly impact our ability to perform complex calculations at scale.

Please note that this role is split over two levels and the Level 4 offers a salary of £36,397 – £38,620 (inclusive of MPP) and the Level 5 offers a salary of £49,396 – £52,293 (inclusive of MPP). Your level will be assessed as part of the interview process.

What will you be responsible for?

As an HPC Computational Engineer you will support the work of the Advanced Engineering Simulation (AES) group. You will have some expertise in the numerical and practical aspects of software development for the development of tools for engineering applications (e.g. finite element, finite volume, iso-geometric analysis, monte carlo, discrete ordinates). In the role you will take ownership of particular tools or physics domains and support developments in the area of digital engineering.

This role will allow you to develop engineering (and physics) software, with a focus on performance and scalability. You will interface with engineers and scientists working on particular problems, and through co-design come to efficacious solutions to problems.

Key areas of responsibility will include: 

Level 4

  • Support the migration of codes to new computing architectures
  • Perform detailed code analysis including performance evaluation (e.g., roofline analysis)
  • Support users in containerisation of their codes
  • Contribute to development of performant and highly scalable engineering codes

Level 5

  • Lead small teams of 4-6 people(L5)
  • Help develop and support a MBSE approach with state of the art PLM systems, and design digital twins for existing and forthcoming devices.
  • Perform your own research into novel numerical techniques with applicability within the fusion community and beyond
  • Project reporting and ensuring project milestones are met in a timely manner and within budget
  • Actively seek out new research and funding opportunities
