Job Highlights
About the Role
As a Fluid Systems Design Engineer, you act as an integrator, combining deep technical knowledge from multiple disciplines to create reliable, functional submarine systems. This involves justifying design, build, commissioning and operational decisions across the platform. You will lead the Operations Section of the Dreadnought Fluid Systems team, managing a group of approximately three engineers, setting tasks, deadlines and delivery, and supporting people development alongside the Group Leader. Responsibilities include developing design phases for primary system operations, defining the operating philosophy for the Dreadnought platforms, and taking technical ownership of protective safety measures. You will update and improve nuclear safety case documentation, verify operating principles, define PWR3 operating principles, and help produce operational and test procedures in collaboration with MoD, the Royal Navy and industry partners. The role also supports commissioning of the Nuclear Steam Raising Plant’s primary systems, both remotely via technical queries and on‑site at Barrow. • Lead the Operations Section, overseeing ~3 engineers and managing tasks, deadlines, and development. • Develop design phases and operating philosophy for primary submarine systems. • Own and update nuclear safety case documentation and verify operating principles. • Define PWR3 operating principles and create operational and test procedures with MoD and Royal Navy partners. • Support commissioning of the Nuclear Steam Raising Plant’s primary systems, both remotely and on‑site. • Apply knowledge of nuclear safety case methods, fluid dynamics and thermodynamics.
