Principal Engineer – Product Assurance (Nuclear)

If you have an interest and a passion for the highest standards within engineering design, build and commissioning, then BAE Systems has the perfect opportunity for you. We are looking for you to join our Nuclear Safety Assurance team, which is responsible for providing assurance that that the activities being undertaken to design, build and commission the Naval Reactor Plant (NRP) for both the Astute Class (PWR2) and Dreadnought Class (PWR3) Submarines deliver a safe, fit for purpose product that meets the requirements of the customer and nuclear regulators.

As a Principal Engineer – Product Assurance (Nuclear), you will be responsible for the assurance of reactor safety for the Naval Reactor Plant (NRP) which presents special challenges to the organisation. The Engineering Product Assurance Dept (EPAD) provide a product engineering assurance service to assure the organisation that appropriate evidence and arguments exist to demonstrate that the NRP product is conforming and meets its intended safety claims. You will also provide formal support through a Service Level Agreement to the Whole Boat Technical Authority (WBTA) in the discharging of duties which are considered to be a delivery responsibility of the WBTA rather than assurance activities that should be conducted under the remit of an independent assurance department.

This role offers the candidate the opportunity to gain in-depth knowledge of the Naval Reactor Plant for both the PWR 2 plant integrated into the Astute Class and the new PWR 3 plant to be integrated into the Dreadnought Class of submarines.The role provides a rare opportunity to be involved in a broad range of the Engineering Lifecycle for a Naval Reactor Plant, from Engineering design reviews through to build, test and commission activities, including resolution of emergent issues providing live support to the Engineering and Build & Commissioning teams and providing through life assurance for the final integrated product.

Your main responsibilities as a Principal Engineer – Product Assurance (Nuclear) are as follows:

To deputise for the Nuclear Safety Assurance management team as required.

To confirm beyond reasonable doubt by review, surveillance and assessment, that those assumptions underpinning the safety case, analysis methodologies and interpretation of results have been validated.

To produce evidence in support of qualification, legislative requirements and safety justifications and provide specialist support for associated activities.

Provision of advice to the company on the nuclear safety impact of NRP design change and any issues arising during build and commissioning activities that potentially challenge the original design intent justified by the NRP Safety Case. [This includes support to Commercial teams as contracts impacting nuclear safety requirements of the plant are placed on the business].

Provide assurance of the adequacy of Nuclear Safety Case documentation provided by MoD to BAES as Government Furnished Information to support design, build, commission and operation of the Astute and Dreadnought Class submarines.

Draw together evidence from across the build environment to construct a robust demonstration that the extant processes and organisation support the requirements of Design Intent in the NRP Safety Case.

Support resolution of independent nuclear safety assessor concerns raised against issued documentation.

Support Nuclear Assurance activities for both the Astute & Dreadnought programmes

Conduct Fit for Purpose Reviews of NRP Safety Case documentation procured by BAE Systems on behalf of MoD.

Author safety case maturity statements to provide assurance to BAES and the MOD of the adequacy of the ‘as built’ plant against design, build and commissioning requirements presented in the NRP Safety Case to support of entry into nuclear build phases.

Carry out Nuclear Safety assessment of Naval Reactor Plant design changes to determine impact to Design Intent, and subsequently provide advice and support to Engineering to ensure conforming and compliant product is delivered.

To liaise with both internal and external customers as required ensuring that their requirements are adequately supported and that their needs are fully considered and incorporated where appropriate and agreed.

Your skills and qualifications:


Degree level qualification (or equivalent) in a relevant subject such as Engineering or Physical science

Extensive engineering experience in design and build of engineering systems, including a thorough understanding of the role that safety and quality play in achieving a conforming product

Understanding of the design, build, commissioning and operation of Reactor Plant systems

Familiarity with Naval Reactor Plant an advantage

The ability to analyse complex problems and identify the most safety critical issues

A strong understanding of the ALARP principle

Capable of communicating via written and oral briefings and technical reports

Safety Case experience in a high hazard industry, e.g. Nuclear, Chemical, Oil & Gas etc.

Understanding of Nuclear Regulation

Experience of conducting root cause investigations

Ability to lead Engineering investigations


Strong general engineering background and/or Ex NRP Operator

What we're looking for in you:

You will have excellent communication skills at all levels with the ability to challenge and influence others, whilst putting forward clear, concise and credible reasoning to support judgements.You should be able to engage with a broad range of key internal and external stakeholders and be collaborative in your approach in order to build positive, effective and trusted relationships.
