IT Services

Advanced. Powerful. Large-scale.
There’s no limit to the systems we support.

We deliver technology to the heart of the mission.

In IT Services we deliver the infrastructure that GCHQ needs to meet business demands and the speed of the mission. This involves developing healthy partnerships with different areas of GCHQ, as well as the IT industry, partner agencies and academia. Most importantly, we aim to be easy to do business with, providing efficient, affordable and innovative solutions to meet the needs of the mission.

Using our expert knowledge of technology, opportunities and the mission, we demonstrate the art of the possible, while maintaining the right balance between stability and agility.

It’s an exciting and fun place to work, where you can develop a rewarding and fulfilling IT career in one of two areas.

IT Infrastructure Engineering

It takes a world class infrastructure to enable cutting edge system development, ground-breaking analysis and innovative data processing. Our infrastructure engineers design, implement, support and maintain a complex and technologically advanced IT infrastructure that ranges from critical legacy systems to cutting edge technologies. As well as providing consultancy and support to other engineering areas, we also partner with industry to design and implement large scale and complex systems.

Because our business is always evolving, we tackle ever more demanding customer requirements. This means we need high calibre engineers who combine excellent technical skills with a constant desire to stay on top of technology to deliver a capable and reliable infrastructure.

IT Operations

IT Operations provides a wide variety of IT services, all of which are vital in enabling the work of GCHQ. We have teams providing front-line support, recording, identifying and resolving incidents and problems, planning and managing system changes and outages, and overseeing systems transitions, releases and deployment. Other specialist areas are involved in data centre management, managing software assets and IT accounts and configuration management. We are also the people who ensure the security of GCHQ's own systems. All these posts underpin GCHQ's technical capability, which is constantly evolving, providing exciting and fast-paced work.
