Technology, Engineering & Research

Our technologists and engineers use sophisticated software, hardware and brand-new IT systems to help other teams to carry out their operations. We’re specialists across cyber security risk, complex data analysis and programmes, and across platforms, networks and infrastructure. While we’re there to support on-going operations, we also respond to critical world events. If you’re curious about the potential of tech, you’ll quickly settle in.

Roles & responsibilities

Developers and programmers

We have a huge range of roles that are dedicated to creating valuable software and tools. This helps us to collect important intelligence. You’ll have the freedom, time and support to develop software or use reverse engineering, penetration testing and intrusion detection skills.

Working on networks, platforms and infrastructures

Using your understanding of end-to-end computer networks, platforms and infrastructures, you’ll collaborate with intelligence teams to work against threats. It’s a unique way of applying your skills. You’ll do everything from analysing networks and remedying vulnerabilities on specific platforms to addressing security on larger infrastructures. 

Complex data analysis

Data analysis is crucial to our work. It means compiling and preparing data – which is usually big, complex and diverse - and analysing it. Building the right tools, adopting the right techniques and drawing meaningful conclusions, you’ll help us to understand and act on intelligence.

Advising and consulting on cyber security and risk

We have a range of roles dedicated to guiding our customers and colleagues to manage cyber threats. You’ll bring your insights and understandings of cyber security and how platforms, networks and infrastructures are vulnerable. And with a shared purpose, you’ll draw in the right teams, all working together to solve problems.

Deep technical specialism

We have hundreds of specialist roles, ranging from experts in communication technologies to specialists in quantum computing. It’s a chance to use unique skills in specialist areas, helping us to collect and use intelligence.


We spend a lot of time researching threats. So we also take the time to understand the tech behind them. Our researchers constantly take systems apart, test different theories and assess new ideas. You'll make data easier for people to use and reduce any risks. There are lots of applied research groups across GCHQ, but we work together and share our learnings.

Tech Talent Network

If you have a tech background and you are interested in joining us, but you’re not ready to apply yet, then our Tech Talent Network may be perfect for you. As a member, you’ll get access to exclusive content and events, along with job alerts tailored to your area of expertise.
