Your Impact

The Nuclear Safety Case Engineer is a key role within the Sizewell C Design Authority, reporting directly to the Safety Case Group Lead. This position offers the opportunity to play a central role in the development and delivery of the project’s nuclear safety case strategy.

You will lead the development of a range of complex nuclear safety cases, ensuring they are robust, compliant, and aligned with regulatory expectations. This includes ownership and coordination of SZC’s top-level safety case-currently the Pre-Construction Safety Report (PCSR)-as well as supporting the evolution toward the Pre-Commissioning Safety Report (PCmSR) in the next phase of the project.

Working collaboratively across engineering, design, and regulatory teams, you will ensure that safety arguments are clearly articulated, evidence-based, and integrated across all aspects of the plant design and lifecycle.

Principal Accountabilities, Activities and Decisions

  • Own the safety case during the design, construction and commissioning phases, advising the regulator, internal stakeholders and the responsible designer on its adequacy.
  • Lead PCSR and PCmSR section development, including strategy setting, team leadership, and progression through the safety case lifecycle (authoring, peer review, verification, regulatory review and approval).
  • Act as an intelligent customer for the safety case by providing technical oversight across licensing, procurement, manufacture, construction, commissioning and operation phases of the station lifecycle.
  • Develop and maintain effective working relationships with a wide range of stakeholders, including internal teams, external partners and regulators.
  • Maximise the benefits of replication from Hinkley Point C to Sizewell C.
