Full time
Job Description
Imagine playing a key role in transforming two of the UK's most historic nuclear research sites into safe, clean, future ready spaces. At Harwell, just south of Oxford, and Winfrith in Dorset, we're progressing through some of the most exciting and technically challenging decommissioning projects in the world, removing legacy waste, dismantling complex facilities, and ultimately returning these pioneering sites to green field status.
Could you be our next Senior Safety Case Engineer? In this pivotal role, you'll deliver high-quality nuclear safety cases and supporting documentation that enable fast-moving decommissioning work and ongoing site safety case requirements. Every project you touch brings a new challenge: from retrieving historic research waste at Harwell to helping decommission the world's first high-temperature helium-cooled reactor at Winfrith using remote operations and laser cutting. If you're driven by meaningful impact, inspired by engineering firsts, and ready to join a team known for excellence and innovation, this is your opportunity to help shape the next chapter of UK nuclear decommissioning.
What will you be doing
In this role, you'll lead the strategy and delivery of safety cases across the Harwell and Winfrith sites, acting as Safety Case Project Manager, Author or Verifier depending on project needs. You'll write and review complex safety cases in line with company standards, ensuring they remain accurate, robust and fit for purpose. Alongside this, you'll maintain existing safety cases and support the full modifications process, helping to keep each site compliant and operationally safe. You'll also oversee the production of inputs from other contributors, managing the development and coordination of all safety case deliverables to ensure high-quality and timely outputs across a diverse portfolio of decommissioning work.
Who we are looking for
You'll bring a degree or equivalent NQF Level 6 qualification in a relevant technical discipline such as mechanical engineering or physics, along with detailed knowledge of modern nuclear safety case standards, processes and methodologies. You will have hands-on experience delivering safety case projects, including resource coordination, and a strong understanding of engineering safety principles and the derivation of Safety Functional Requirements. A thorough grasp of Site Licence Conditions, statutory and mandatory requirements, and safety case management activities, such as production, verification, INSA and implementation is essential. You'll also have practical knowledge of safety case applications specific to nuclear decommissioning, including fault schedule development and ALARP justification, supported by strong environmental awareness.
