GCHQ protects the nation from established and emerging threats to security, including cyber attacks, international and domestic terrorism, organised crime and the proliferation of nuclear, biological and chemical weapons.

You could be involved in researching and assessing cryptographic and network security algorithms, systems and equipment, developing novel techniques for analysing challenging datasets, and implementing new mathematical techniques to support the security mission. Throughout you’ll help solve some extremely complex theoretical and practical problems.

In the first few years, you can expect to move around different areas to gain a broad understanding of the range of problems we tackle. For example, you may take part in intelligence and Information Assurance work, and perhaps consult and advise government and some sections of industry on cyber-security. You’re also likely to work closely with other mathematicians and with specialists in other fields such as networks, software engineering and IT security.

You could join us as a fresh graduate, or with some postgraduate research experience in industry or academia, or at postdoctoral level. You may have knowledge of relevant areas such as algebra, combinatorics, number theory, probability theory and statistical data analysis.

With the ability to come up with innovative ideas, you’ll be a confident communicator both in person and on paper. A willingness to learn about software and emerging technologies is essential.
