Technology careers that make a difference

Our digital intelligence operations teams work at the sharp end of MI5's technical intelligence gathering operations, using well-established, cutting edge and bespoke technologies to meet complex challenges in a digital age.

Working closely with investigators and more traditional collection teams you will play an integral role in helping us to collect and analyse intelligence from a wide range of digital sources to better understand and disrupt the threats from terrorism, espionage, cyber-attack and those that seek to harm the UK's interests.

Most roles are desk-based but there are some where you could be working outside or collaborating with external partners and suppliers to achieve our aims. We're looking for people from a wide range of backgrounds and IT disciplines. Some roles you may be familiar with, some are unique to MI5. One thing we guarantee is whatever you do you will be making a difference.



Roles in digital intelligence operations

MI5 offers many different roles for those with IT skills and a passion in technology, some of which can be seen below. If we're not currently recruiting for the role you're interested in but you'd like to receive future updates, you can register your details.

Operational Network Engineer

The Operational Network team is responsible for the rollout and maintenance of MI5’s operations networks throughout the UK. This team takes the lead in deploying a wide range of advanced MI5 technical capability to enable intelligence collection in fast-paced and high profile investigations. The role has two key elements. Firstly, you’ll be responsible for building relationships with suppliers and organisations who work with us on sensitive projects. Importantly, the role also covers supporting and conducting live operations. You will work to tight deadlines which include solving technical problems in a tactical and covert way. Experience in a commercial data-centre and/or large networks would be an advantage.

Operational Infrastructure Engineer

The Operational Infrastructure team is responsible for maintaining the IT infrastructure that supports several high availability systems. These systems handle large amounts of real-time data to support our investigations. The focus is on maintaining and improving systems, their performance, patching and upgrade paths, and systems security and integrity, whilst also ensuring value for money from our third party support agreements. Your core responsibility will be the support and development of a range of operational systems and deliverables (including fault diagnostics), active participation in development projects (trialling, testing and evaluating kit) and reacting flexibly and in a timely manner to operational priorities. In this role you’ll gain experience of running IT services in a challenging operational environment and participate in, and carry out, research and development activities.

Cyber Technical Analysts

Our cyber technical analysts provide specialist technical analysis to help progress our investigations against hostile actors conducting cyber espionage against the UK. They utilise network and host-based forensics skills, protocol analysis, reverse engineering and bespoke tools to understand the threat posed by malicious groups. They also develop new and innovative tools for MI5 to continue to advance its analytical capabilities.
