Careers at MI5
A career at MI5 is like no other. Not only is it rewarding and unique, but the variety is unlike anywhere else. Our employees have significant autonomy to manage their own careers and the opportunity to change jobs or business areas every two to three years. It wouldn’t be unusual for someone to work in counter-terrorism, recruitment, counter-espionage and corporate communications within their first few roles. This variety together with our supportive and flexible working environment means most people who join MI5 stay for a substantial part of their careers.
