Job Description
This is where your skills play a critical role in keeping everyone safe. Working in Safety, Security & Safeguards gives you the chance to make your mark on some hugely interesting projects. UKNNL does work that nobody else in the sector is doing, and this means we need experts like you to make it possible, whilst keeping everyone safe. We’re committed to using nuclear science to benefit society for years to come. This means that you can build a long and successful career here whilst playing a meaningful role in delivering cleaner energy, reducing waste and keeping colleagues and the public out of harm’s way.
As the national laboratory for nuclear fission in the UK, we are harnessing nuclear science to solve some of the world’s biggest challenges.
The Measurement and Analysis, instrumentation and in-situ analysis team (M&A-IIA) are involved in development of new technologies for radiometric applications and deployment challenges.
The team are looking for an individual to join this growing team to play an important part in allowing UKNNL to fulfil future commitments and develop into a subject matter expert for future programmes of work and become a technical lead.
To join the UKNNL Post Doctorate programme you will have a PhD in radiometric physics, nuclear instrumentation or similar and able to work with engineering, sensor and instrument suppliers.
You will have the right to work in the UK and be able to achieve SC level security clearance (this includes but is not limited to identity, employment, financial and criminal record checks plus 5 years’ worth of UK residency).
Main Responsibilities
We are developing the next generation of technical experts.

You will have the opportunity to work on innovation projects for radiometric instrumentation and customer work for the future, develop your knowledge of radiometric detectors and experience in radiometric systems, and help the Measurement and Analysis, instrumentation and in-situ analysis team deliver decommissioning for the Sellafield site.
You will support research and other customer work, experimental design, provide experimental data, data analysis, testing and underpinning evidence for instrumentation and processes.

You will have direct sight of the value that your skills and knowledge have to our industry and by extension our society. The Postdoctoral Development Scheme runs alongside your role, providing you the space and skills to develop in a commercial environment whilst helping you decide how to advance your technical expertise.
