Senior PSA / Nuclear Risk Engineer

Shape the risk models behind the UK’s next generation of nuclear programmes.

We’re supporting a confidential organisation involved in major nuclear programmes across the UK and internationally. They are expanding their capability in probabilistic safety assessment and nuclear risk analysis and are looking for experienced engineers who want to play a deeper role in how complex nuclear systems are assessed and understood.

This role sits within multidisciplinary engineering teams, contributing directly to safety cases, risk-informed design decisions, and technical risk studies across both new nuclear projects and existing facilities.

For some engineers working in PSA today, the work can become narrowly focused — maintaining models without seeing how the results influence engineering decisions.

This opportunity offers a broader perspective.

You would be contributing directly to fault tree and event tree modelling, reliability assessments, and risk-informed engineering decisions across complex nuclear programmes. The work connects safety analysis with the wider engineering teams responsible for system design, operations, and safety case development.

The technical work includes:

Developing and maintaining fault tree and event tree models

Performing probabilistic safety assessments (PSA/PRA)

Supporting nuclear safety cases and risk-informed decision making

Producing technical safety and risk analysis reports

Working alongside engineering teams across complex nuclear projects

Experience with tools such as RiskSpectrum, CAFTA, SAPHIRE, or similar PSA software is valuable, and familiarity with UK nuclear regulatory frameworks will be beneficial.

The role is hybrid, with regular presence near Bristol, placing you close to one of the UK’s key hubs for nuclear engineering.

If you have experience in PSA, PRA, or nuclear risk analysis, and are interested in contributing to complex nuclear programmes where risk modelling directly supports engineering decisions, we would be glad to start a conversation.
