Job summary

Do you want to be at the heart of real Defence issues and play a key role in the United Kingdom’s (UK) national security?

Established in April 2016, the Defence Nuclear Organisation (DNO) delivers nuclear capability to deter threats and protect our nation.

The DNO oversees all defence nuclear business (excluding operations) and is responsible for providing nuclear deterrence; sponsoring the Defence Nuclear Enterprise (all the organisations, programmes and people that sustain the UK’s nuclear deterrent); and advising on UK nuclear policy, planning and international co-operation on nuclear matters.

The UK’s independent nuclear deterrent has existed for over 60 years to deter the most extreme threats to our national security and way of life, and that of our NATO Allies. To ensure that we have a credible and capable nuclear deterrent for as long as the security situation requires, we are building four new nuclear armed submarines – known as the Dreadnought Class – and replacing our nuclear warheads. These renewal programmes will utilise world-leading technology and are a showcase in science and engineering, highlighting the prowess of British industry.

Here at DNO we strongly believe that diversity and inclusion is not only the right thing to do but is also essential for a thriving and successful organisation. We know that diverse teams bring a wide range of perspectives, experiences and ideas, which lead to better decision-making, creativity and innovation. We have a culture where differences are celebrated and our people feel supported, included and empowered. Join us and be part of an organisation that truly values diversity and inclusion and makes a positive impact on the world. 

Within DNO, the Finance Directorate supports the spectrum of DNO via a functional operating model. The advertised roles support the Warhead Directorate that leads the UK nuclear warhead programme which provides a stockpile of reliable, safe, and effective nuclear warheads to support the UK’s strategic nuclear deterrent now and in the future.

Our vision for the finance function is: Protecting Value, Driving Value, Adding Value and putting finance at the heart of decision making to support and enable delivery of Defence outputs.

There may be occasional travel to other MOD sites across the Defence Nuclear Enterprise.

The post will be advertised at 37 hours per week.
