About IA&R: The Independent Assurance & Regulation (IA&R) team has a primary focus on three key areas; Independent Oversight & Assurance, Technology Development, and Regulatory Support. We have been directly involved in the Royal Navy’s Nuclear Submarine Program for six decades, as well as supporting the UK Civil Nuclear & Decommissioning industry.

This work requires a general knowledge of the design and operation of the NRP, safety case development and methodologies, and the ability to communicate effectively.

This role is ideal for a confident and ambitious engineer, several years into their career or a seasoned veteran.
