Skills

Requirements

What we're looking for

Degree in a scientific, engineering or technical discipline, plus a PhD or equivalent experience in an academic or industrial research environment.
Demonstrable expertise in at least one compiled language (such as C++, Fortran, C or Rust) or an advanced scripting language (such as Python, Julia or R).
Strong knowledge of modern software engineering practices and advanced computational science, including expertise in simulation development, high-performance computing, numerical methods, or data-driven simulation techniques.
Experience leading computational research projects and delivering robust research software and high-quality scientific publications.
Proven experience applying advanced computational methods to solve complex scientific problems with a high degree of technical responsibility.

UKAEA is an onsite organisation, and this role requires regular onsite presence (usually between 3-5 days in any given week) in line with business needs. We actively support flexible working arrangements where this is compatible with the role.

Pay & benefits

What you'll get

We have a generous range of benefits (see the full list here) and highlights include:

A salary of £64,820 (inclusive of a £6,500 specialist allowance)
Up to 7% corporate performance bonus
Final salary defined benefits pension scheme with an equivalent of 21.5% employer pension contribution
25 days annual leave plus 2.5 'privilege' days; 8 Bank Holidays
Additional 3 days of site closure over Christmas break
Flexible working options plus family-friendly leave provisions

The role

UKAEA is seeking a senior numerical methods specialist to help establish and grow our capability in advanced numerical methods for fusion science and engineering.

We are looking for someone with deep expertise in one or more areas of computational mathematics.

Relevant areas could include high-order finite element methods, advanced linear and nonlinear solvers and preconditioning, structure-preserving methods or statistical and particle-based numerical methods.

This list is deliberately not exhaustive: we are particularly interested in candidates who can bring new mathematical and computational approaches to challenging problems across UKAEA.

Background knowledge of plasma physics or fusion energy generally is desirable but not essential.

The successful candidate will work across UKAEA to identify scientific and engineering problems where advanced numerical methods can make a significant difference, develop and demonstrate new approaches, and help translate methodological research into practical simulation capability. They will need to act with a high degree of independence. They will also build strong relationships with universities and the wider numerical mathematics community, establishing collaborations that connect UKAEA problems with leading research in computational mathematics.

We are therefore looking for someone who combines deep technical expertise with intellectual curiosity, initiative and the motivation to build a new capability from the ground up.

What you'll do

Develop and apply advanced numerical, statistical and computational methods to address complex scientific challenges.
Lead significant computational projects and work packages, delivering high-quality scientific outcomes.
Provide specialist expertise in a defined area of computational science and help shape research priorities.
Design, develop and enhance simulation tools, models and computational workflows.
Ensure scientific quality, reproducibility and technical rigour across research activities.
Identify, assess and mitigate technical and scientific risks within projects and modelling approaches.
Evaluate and adopt emerging computing technologies and numerical methods to advance research capability.
Guide technical approaches and research direction in collaboration with scientific and technical specialists.
Mentor computational scientists, researchers and doctoral students within your area of expertise.
Contribute to external collaborations, technical review activities, publications and conference presentations.
