About Us

MI5 safeguards the UK against threats such as terrorism, espionage, cyber-attacks and sabotage. We investigate suspect individuals and organisations in the UK to obtain, collate, analyse and assess secret intelligence relating to these threats. And alongside our British Intelligence partners MI6 and GCHQ, we provide the UK government with the information they need to protect national security. At MI5 you’ll enjoy varied and rewarding work in a supportive and encouraging environment that puts the emphasis on teamwork.

The role

As an MI5 Security Officer, you’ll help to protect our assets, people and places, and make our complex security operation a success. You’ll work with a team of motivated professionals to provide a reassuring presence, while conducting a range of security duties and responsibilities. For example, you will interact with colleagues from all areas of the organisation, operate our bespoke security control room and monitor CCTV and alarm systems. You will also use security architecture (e.g. CCTV and Access Control systems) to maintain security assurance across our estates – proactively mitigating and reporting potential security breaches. You’ll also be responsible for processing visitors and vehicles into our buildings, and engaging in incident and emergency response, while supporting our first aid and business continuity needs.

About you

It takes people from a variety of backgrounds to help us tackle the threats we face, and MI5 is committed to reflecting the society we protect. For this reason, our Security Officers have a wide range of previous experience, and you don’t need any security awareness to apply. Instead, you’ll have good customer service skills and be keen to learn. You’ll need to enjoy working in a team, be able to keep your composure and understand when to be insistent. 

You’ll also need to communicate comfortably with a range of people, remaining calm when under pressure, and be able to think clearly and take timely action in an emergency.

With excellent attention to detail, you’ll compile accurate written logs, taking care to write clearly and concisely. Proactive and motivated, you’ll be an effective time manager with strong administrative, organisational and observation skills. As one of our Security Officers you will be expected to role model the principles of equality, diversity and inclusivity by demonstrating an inclusive and collaborative approach in working with immediate colleagues and when dealing with visitors.

We’ll also expect you to have some basic IT skills, including the ability to use email and Microsoft Office. 

Training and development 

At MI5, continuous learning and development is at the heart of all that we do. You’ll be supported to gain professional security qualifications and to develop other skills. 

We’ll also provide you with suitable tailored and ongoing security practitioner training and mentoring. This will include exposure to our protocols/procedures and security systems as well as customer care, conflict management/resolution and fire safety. Plus, you might have the opportunity to contribute towards project work aimed at further improving our security offering.

You are required to stay within the specialism of the security team for a minimum of 5 years during which time you might apply for promotion, subject to agreement from your line manager and business/organisational needs. After five years you might also seek out other opportunities in other areas of the organisation.

Equal Opportunities

At MI5 diversity and inclusion are critical to our mission. To protect the UK, we need a truly diverse workforce that reflects the society we serve. This includes diversity in every sense of the word: those with different backgrounds, ages, ethnicities, gender identities, sexual orientations, ways of thinking and those with disabilities or neurodivergent conditions. We therefore welcome and encourage applications from everyone, including those from groups that are under-represented in our workforce such as women, those from an ethnic minority background, people with disabilities and those from low socio-economic backgrounds.
