Do you want to be part of an organisation that uses cutting edge technology, makes a real difference to the UK, provides excellent development opportunities, and gives you the chance to build an exciting, challenging and varied career? If you already work in the technology sector, our organisation has a wide number of technology-related roles available, to which applicants are able to apply at any time.

Our organisation is tasked with protecting the country’s people, businesses and interests in the cyber age. Working with colleagues in MI5, SIS (MI6), the MOD, the National Crime Agency, the police, academia (and many others), we gather and analyse intelligence from digital and telecommunications sources, and ensure that IT networks, systems and data are secured against hackers and other threats. Nowhere else will you be able to apply your technology expertise in such a unique environment, against such a varied set of challenges and with such interesting colleagues!

Our organisation has headquarters in Cheltenham – geographically located within an hour of Bristol and Birmingham – as well as Bude, Harrogate, Lincolnshire, Manchester, London and Scarborough. Despite the (necessary) secrecy around some of what we do, the urgent nature of our mission means there will always be opportunities to work with partners, industry and academia from across the UK, and even to re-locate between offices.

At our organisation we’re proud of our inclusive and supportive working environment that’s designed to encourage open minds and attitudes. Just as we offer a wide range of roles – specialist, technical as well as more general roles (HR, project management, finance, leadership…) - so too do we welcome applicants from a wide range of backgrounds. To do our job – which involves solving some of the hardest technology problems the world faces - we need all talents and we need people who dare to think differently. In return, along with excellent training and development options, we’re committed to providing a healthy work/life balance that enables you to perform to the best of our ability.


Solving the unsolvable

Our organisation has a number of openings for mathematicians with post-graduate experience and expertise for research and development positions.

Our mathematicians solve varied and interesting problems, often using some of Europe’s most powerful computers and other leading edge technology.  Our work requires problem-solving skills and a broad range of mathematical approaches, in a range of areas such as cryptography and cryptanalysis; network exploitation and security; protocol analysis; statistics and data science; signals and media processing; mathematical modelling; understanding challenging data sets and streams; hardware analysis; information assurance; and cyber security.  The variety of work is also reflected in a variety of outcomes, ranging from cutting edge capabilities delivered by interdisciplinary teams; the provision of world-class expertise to support the UK’s critical infrastructure and assets; and the opportunity to influence decisions made by government agencies.

Further details on the range of work carried out by our mathematicians can be found at


Candidates will need to have a 2:1 degree or above with a strong maths content and a minimum of 2 years relevant experience of using their maths after graduation – either in the workplace or through post-doctoral study or research.  

Applications are welcome from candidates with experience in any area of mathematics and statistics or in disciplines such as theoretical physics or computer science provided they have a strong mathematical component: internal training will be given.

To apply for this role you will need workplace experience of at least a year. If you are a current or recent graduate please consider our Technical Graduate Opportunities which we will be launching autumn 2017
