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.
