Maths & Cryptography

We’re GCHQ, and we unlock the complex world of communications to make a real difference to the safety of the nation. Alongside our partners in the UK’s Intelligence Services, we safeguard Britain’s people, interests, and businesses from threats such as serious organised crime, terrorism, and cyber-attacks.

Our work is complex, unique and ever-changing – and it’s informed by the amazing work of our Mathematics and Cryptography teams. In this exciting role, we’ll train you to use your mathematical thinking to tackle varied, complex and vital problems. And the solutions you find? They’ll help to protect the UK.

Working across cryptography, cryptanalysis, network exploitation, cyber security, data science, machine learning and mathematical modelling (to name just a few areas), you’ll receive support and mentoring as we train you to become a maths and cryptography specialist.

Collaborating with colleagues in multi-skilled teams, you’ll help solve an incredible range of interesting problems. In a typical day you might evaluate an existing theorem, or develop a new one. Use some of Europe’s most powerful computers to deliver world-class input on vital security projects. Apply your analytical skills to a broad range of mathematical approaches including algebra, probability, number theory, statistics and optimisation. And complete projects which influence some truly key decisions made by government agencies.

With expert training and development opportunities, you’ll be working as a specialist in no time, producing innovative and one-of-a-kind work which has meaningful purpose. And because of what we do and who we are, our methods and practices are constantly changing so they stay cutting-edge – which means your learning and growth won’t ever stop. This is a role with so much potential, and it could be just the beginning of your career at GCHQ.

To reflect the developing challenges we face, you'll need a background in maths, computer science or any other subject with substantial mathematical content. You should have, or expect to obtain shortly, at least a 2:2 undergraduate degree (or equivalent qualification) in a mathematical discipline, including (but not limited to) mathematics, computer science, statistics, or physics.

The application window for our Maths and Cryptography roles will open on 24th October 2022. In the meantime, we encourage:

•    All those from an ethnic minority background* 
•    Women from any ethnic background* 
to register their interest in this forthcoming opportunity.

*Please note that we are confining registrations of interest to the above group only, due to the current under-representation in our workforce. 

As part of the registration of interest, you will be invited to several online events prior to the campaign opening. There will be a virtual event where you can find out more about the role and we are also offering a Skills Event which will provide general tips about completing a job application, preparing for interview etc. These events will run on:
