About Opportunity

AT&R aims to provide world‑leading consultancy services across highly regulated industries. Organized to be independent and free from conflict of interest, Assurance, Technology and Regulation (AT&R) provides a range of trusted, evidence‑based, support services to ensure that systems, technologies, and processes are safe, effective, compliant, and future‑ready, across 3 main areas:

• Independent Assurance – We provide risk‑based, proportionate, independent oversight and assurance of whether a project, process, system or product meets defined standards, requirements, or expectations.
• Research & Technology – We identify, define and execute programmes of Research and Technology to support the continued safe operation of some of the world’s most complex engineering challenges, including the UK Naval Nuclear Propulsion Programme.
• Independent Regulatory Support – A ring‑fenced and independent organisation that supports regulators with assessments, audits, and guidance development.

About The Role

Our dynamic, customer‑facing Independent Nuclear Assurance (INA) team has been supporting the Ministry of Defence’s (MoD) naval nuclear propulsion programme for over sixty years. A number of exciting opportunities have arisen to join this diverse team of highly experienced staff who provide a key role in supporting the safe operation of the UK’s submarine fleet.

As a Nuclear Technical Engineer, you will help deliver independent assurance services to the MoD. This includes the provision of safety and technical advice for both current and future submarine Naval Reactor Plants (NRP), which involves working with a wide range of technical disciplines to provide balanced, proportionate and timely support.

We are seeking personnel who are passionate about nuclear safety and a desire to work in support of some of the most complex, challenging and important projects within the UK. 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.

We are particularly interested in individuals with an aptitude and enthusiasm for mechanical systems and structural integrity to complement our existing team. Comprehensive training can be provided across a range of technical areas to support development. Therefore, if you feel you meet most but not all the requirements, or work in civil nuclear/high‑hazard industries and are keen to take on a new challenge, we would like to hear from you.

What You Will Be Doing

• Providing authoritative Advice to the MoD through safety and technical assessments.
• Supporting meetings with the MoD and their contractors.
• Co‑ordinating output across a range of relevant technical disciplines.
• Working according to the best applicable safety, technical and regulatory standards against agreed programmes and budgets.
• Working in accordance with business requirements for health, safety, environment, and security, as well as seeking continuous improvements in all aspects of work.

Here’s What You’ll Need

• Degree (Level 6, minimum requirement) in science or engineering (or equivalent).
• Membership of (or working towards) a professional institution is desirable.
• Knowledge or operational experience of the Naval Reactor Plant is desirable.
• Knowledge of safety cases (structures and function).
• Familiarity with related documentation (NRPA NSMAs, DSA02‑DNSR, ONR SAPs etc).
• Clear, concise technical writing and communication skills.
• This role will require security clearance; therefore, applicants should hold or be able to obtain security clearance in the UK.

Our Culture

We put people at the heart of our business, and we genuinely believe that we all succeed by supporting one another through our culture of caring.
