Are you ready to make a real impact in the nuclear industry? Our Safety Case Engineers are at the forefront of ground‑breaking projects, working hand‑in‑hand across the civil nuclear and defence sectors, both in the UK and on a global stage. From next‑generation systems and emerging reactor technologies, like SMRs, to ensuring the safe operation of existing nuclear facilities, we cover the full spectrum of the nuclear lifecycle.

The role of a PSA Nuclear Safety Case Engineer is pivotal. Probabilistic Safety Assessment (PSA) forms the backbone of the safety case, demonstrating that risks are maintained at acceptably low levels. In this role, you'll be instrumental in designing and maintaining nuclear reactors and facilities, optimising safety and reducing risks. Your work will involve crafting and delivering PSA models, delving into data analysis, supporting key decisions on facility design and operations, and presenting your findings through top‑tier technical reports.

We’re excited to hear from professionals with expertise in the application of PSA related techniques in any of the following areas:

• Fault and event tree analysis
• Quantified risk and reliability assessments
• Reliability data assessment
• Hazard identification assessments
• Internal and external hazard evaluation, including dedicated Hazard PSA assessments, e.g. seismic, fire and flood.
• Statistical risk modelling
• System dependency analysis
• Take the next step in your career with Amentum, where innovation meets opportunity.

The key responsibilities for this role are:

• Lead the development and implementation of PSA for major nuclear projects
