Administrative Officers

MI5’s mission is to keep the country and its people safe.  We work to protect the UK from threats to national security, including international terrorism and espionage.

Administrative Officers are at the very heart of MI5. Join us and you’ll be helping to protect the country. You’ll work across a variety of departments, each one offering a range of roles, diverse challenges and direct insight into our fascinating work – everything from tackling cyber to countering terrorism.  You could be organising critical meetings, managing information and records, booking travel, looking after visitors or providing essential support to our intelligence officers. Whatever the task, you’ll play a crucial part in ensuring our organisation runs smoothly.  In fact, we couldn’t operate without you.

At MI5, we protect the UK from a range of threats, including terrorism and espionage. It is fascinating work with real purpose. So, whether you've just finished school or you're coming back to work, join us as an admin officer and be at the heart of what we do.

What does an admin officer do?

Our admin officers are people with great organisational skills. Put simply, they support everything we do. From organising meetings and managing information, or booking travel and looking after visitors, admin officers provide essential support across MI5. It means you'll have the chance to work across a variety of departments. No matter the focus of your role, you'll have a direct impact on our work.

What will you look for in me?

Most people assume we are only after people with lots of experience or a degree, but we're not. We're actually looking for people who have lots of initiative and excellent organisational skills. You will need to be comfortable talking to a range of people and naturally pay great attention to detail. Plus, you will be keen to learn new skills and build a career in admin. That's all.

What support will you give me?

Lots! As soon as you start, you'll go on an induction and be given a mentor so you will quickly get to grips with everything and have a friendly face to help. Plus, there is no such thing as a silly question; everyone is here to support you and we understand that it takes some time to settle in. As you develop, you'll have the chance to go on lots of training courses. You will also be able to take advantage of 'lunch and learns' and chat to other admin officers.

Is it a really serious environment?

We are all here to do a serious job, but that doesn't mean we are serious all the time. We actually become really good friends - perhaps more than any other workplace! Some of that comes down to the fact that we can only talk about our work with each other, and just because we're a friendly bunch.

Is there anything else I need to know?

To work at MI5, you need to be a British citizen, and you will need a real passion for admin. We do have a strict drugs policy, so once you start your application, you must not take any recreational drugs and you will need to declare your previous drug usage at a relevant stage.

How do I apply?

If you click the link below, you will start your application. Providing you're successful at each stage, we'll ask you to fill in some eligibility questions, initial application form then take two online tests. You will then complete the full application form, a telephone interview and a face-to-face interview. Finally, you will go through a security interview where we'll ask you about your life and experiences. It is a thorough process that can take up to a year to complete, but it's all to keep you safe.

Work-Life Balance

A common misconception is that due to the nature of what we do, there is no work-life balance at MI5. However it’s important to us that staff maintain their personal commitments and home-life, so where operations allow MI5 also offers flexible working, giving staff more choice in their working pattern.

Plus, we’re not able to take our work home with us, so when you leave the office, you really are leaving your work behind too.

Support and Environment

Whether you join us full or part-time, you’ll have plenty of opportunity to broaden and enhance your administrative skills.  From the outset, we offer a range of training courses and chances to develop your career.

As a new starter to MI5, you’ll be assigned a mentor to guide and support you.  On-the-job training will familiarise you with our systems and processes.

Teamwork and communication is essential to our work.  Everyone at MI5 is called by their first name, which means there is no hierarchy and makes it a really friendly place to work.

Discretion and Social Media

Due to the sensitive nature of our work, you will need to be very discreet.  However, even though you can’t tell your friends what you do, it doesn’t mean you can’t use social media or lead a normal life!
