Job Description for Chemical and Research Analyst
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.
The Measurement and Analysis team at Sellafield have unique expertise, providing the key skills required to support the UK’s future nuclear programmes as well as playing an important role in several international collaborations. The team predominantly supports large scale technical programmes of work such as post-irradiation examination (PIE) isotopic analysis.
The United Kingdom National Nuclear Laboratory (UKNNL) is seeking a post doctorate level chemist with experience in analytical chemistry to join this team. The individual should also enjoy laboratory working and be comfortable with developing their theoretical and practical knowledge in the field of nuclear science and technology. The role will provide resilience to the team across a number of process and analytical chemistry disciplines and support the delivery of R&D programmes to our customers.
Many of the challenges you will work on are unique and therefore most important is the curiosity to learn and the ability to apply your knowledge to practical scenarios. The role will provide you with the opportunity to be involved at the earliest stages of some of UKNNL’s highest-profile programmes of work, allowing you to build up your knowledge and experience through practical exposure.
You will work with a multidisciplinary team of scientists, engineers, safety case specialists and plant operators. We will look to you to understand problems and draw on your technical skills and knowledge to provide robust technical solutions. The successful candidate will work predominantly in controlled areas within UKNNL’s Central Laboratory, reaching out into other UKNNL facilities such as Windscale and Workington laboratories, with limited opportunities for home working. Experience in the radiochemistry or radioanalytical chemistry is desirable but not essential, as all training will be provided but the ability to obtain SC clearance is essential.
Main Responsibilities for Chemical and Research Analyst

Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
