How Does It Work?

We run a transparent recruitment process which varies according to the role. We don’t accept CVs unless required for a specific role. This is a 6 to 9 month process, as candidates have to go through a vetting procedure in addition to the recruitment process for the specific role they have applied for, due to the sensitive nature of our work. 

You may only submit one application at a time and before you apply, you must meet our eligibility criteria.

In 2018 MI5’s attrition rate was 4.5%. This is lower than the civil service (12%) and the UK average (15%).
Just over 20% of all MI5 staff work a flexible job pattern
Just over 40% of MI5 staff are female


Owing to the sensitivity of our work, discretion is vital. You should not discuss your application, other than with your partner or a close family member, providing they are British. You should also make them aware of the importance of discretion. You should not mention your application on social media or discuss it with anyone else at this stage. You will receive further guidance during the recruitment process.


These depend on the requirements of the role. Some of our vacancies require specialist qualifications and/or previous experience and we recommend that you take time to familiarise yourself with the appropriate job-specific pages before you apply. There are also common personal attributes that we look for across all the roles that we recruit for, including honesty, integrity and the ability to work as part of a team.


Every applicant will receive bespoke cover advice (what you may consider telling family and friends) throughout the recruitment process. Should you be successful in joining MI5 you will be given a full briefing on the reasons why it is important not to disclose that you work here, and what to say if people ask you or your family about your career.

MI5 Postings & CVs

The variety of jobs, outstanding team environment and rewarding nature of our work means MI5 is one of the few organisations that can still claim to offer a career for life. Should you join and later find yourself looking for a job outside MI5, you will benefit from a team of careers experts who can help tailor your CV and translate the skills you have developed into a format suitable for the wider working environment, whilst also protecting your cover.
