What's it all about?

There are a variety of roles in the Security Service. These range from investigative and operational roles to support jobs like vehicle technician or security guard.

Depending on your role, your day-to-day duties may include:

  • collecting information on threats to national security
  • watching and reporting on suspects’ movements and actions
  • using specialist IT or electronics equipment to record and observe meetings, conversations or activities
  • reading emails and letters and checking social media
  • deciding if something poses a potential threat

In some roles you’ll work closely with the police, Secret Intelligence Service (SIS or MI6) and Government Communications Headquarters (GCHQ).

You must be at least 18 and meet strict residency and nationality criteria. Due to the sensitive nature of the work, you’ll have background checks carried out through a vetting process.

You’ll need at least a 2:1 degree in a relevant subject for some roles, like:

  • intelligence analyst
  • internet and computer technology specialist
  • security exploitation officer
  • foreign language analyst
  • Russian intelligence analyst

Relevant degree subjects include:

  • history
  • languages
  • politics
  • economics
  • maths
  • law

You may not need a degree for some roles, like security officer or foreign language analyst, but you'll need relevant skills and experience.

For support jobs like business officer or administration assistant, you may need 5 GCSEs (A* to C) including English and maths.



You could get into some roles through an apprenticeship.
