Administrative Officers

Introduction to Administrative Officers

MI5’s mission is to keep the country and its people safe. It means we have really rewarding careers that rely on people with varied backgrounds, ages and skills – just like our Admin Officer role. Whether you’ve just finished school or are returning to work after a break, whether you choose to work full-time or part-time, you’ll have a hugely positive impact and be at the heart of what we do. It’s a chance to develop your skills and get plenty of support along the way.

What does an admin officer do?

You’ll do lots of different things as you’ll work across a variety of departments. Each one offers a range of roles, diverse challenges and interesting insights. Day-to-day, you’ll be organising meetings, managing information and records, booking travel, looking after visitors and providing essential support to our intelligence officers. It’s all about helping us to run smoothly.

Who are we looking for?

We’re after lots of initiative and great organisational skills. You’ll also need to be comfortable talking to a range of people and paying close attention to detail. And if you’re keen to learn new skills, you’ll have all the makings of an excellent Admin Officer. You’ll also need two GCSEs (or equivalent) in Maths and English, at grades A*-C / 9-4. Or, you’ll have relevant experience within an office and/or admin role.

We’re interested in all the things that make you, you. So there’s really no ‘type’ of person we’re after. And if you consider yourself to have a disability or long term condition we offer adjustments in the recruitment process and support you throughout your career.

This role has given me the opportunity to train in different areas and I’ve carved out such an interesting and unique career.

What support will you give me?

Lots! As soon as you start, you'll go on an induction and be given a mentor. You’ll quickly get to grips with everything and have a friendly face to help. And we understand it takes some time to settle in, so there really is no such thing as a silly question and everyone is here to support you. As you begin to develop, you’ll go on training courses and take advantage of 'lunch and learn sessions'. There is a network group for Admin Officers, where you will get to chat to other people doing the same role.

Is it a really serious environment?

We have a serious job, but that doesn’t mean we’re serious all the time. Everyone’s called by their first name and as we work in a collaborative environment, friendships develop – perhaps because we can talk about our work with each other, but mainly because we’re a welcoming bunch. It’s a very collaborative and supportive place to work and teamwork really is key.

Can I still use social media?

Due to the sensitive nature of our work, you’ll need to be discreet. But don’t worry - while you can’t tell your friends what you do, you can continue to use social media and lead a completely normal life.

What's the work-life balance like?

A lot of people think that all our roles must just be work, work, work. But that’s not true. It’s really important that everyone has a great work-life balance. That’s why we offer part-time working, job sharing, compressed hours and flexible working opportunities.

What benefits can I expect?

We know you’ll work really hard, so we want to make sure you’re rewarded for it. You’ll receive a starting salary of £25,876 and other benefits including: a desirable pension scheme, generous parental leave, and 25 days of annual leave. We also encourage flexible working, so we have a flexi-time scheme and offer part-time working and job sharing where possible. There are also lots of facilities at our site, such as a gym, restaurant and coffee bars. And we also host lots of social events so that everyone can get together outside of ‘work’.

Is it an inclusive place to work?

Whatever your idea of the kind of people who work here, you’ll find we’re just ordinary people doing extraordinary jobs. We work hard to ensure our people can bring their whole self to work. Aside from fostering a welcoming, supportive and open culture, we’ve got a range of growing affinity groups. These currently include:

  • our ethic minority network
  • a group working to achieve gender and non-binary equality
  • a network supporting staff with illnesses and disability
  • an open forum for staff with a faith, or no faith, to come together
  • our network supporting LGBT+ staff.

Disability confident employer

We’re a global organisation that represents and defends the UK’s interests. So, naturally, Diversity and Inclusion is at the top of our agenda. It’s essential that we have a diverse workforce and provide an inclusive workforce. We aim for everyone’s differences to be celebrated, and to create a workplace where everyone feels encouraged and supported.

As well as supporting you throughout the recruitment process, including offering a range of adjustments, we’ll ensure you have the right support throughout your career. We have a dedicated disability network group, which aims to build awareness of disability through internal talks, activities and social events. 

We’re also proud to be a ‘Disability Confident’ organisation and to have achieved ‘Leader’ status within the Department for Work and Pension’s scheme. We ensure that a fair and proportionate number of disabled applicants that meet the minimum criteria for this position will be offered an interview. (This is known as Offer of an Interview.) To secure an interview for this role, the minimum criteria (in order of application process) are:

  • Two GCSEs in Maths and English at grade 9-4 (A*- C or equivalent)
  • Successfully passing a question about your motivation for applying for the role
  • On completion of the application form, you will be invited to an online interview. This is your offer of interview.

Our commitment demonstrates the importance we place on equal opportunities and it means that we also:

  • Do our best to accommodate adjustments
  • Allow extra time during selection ‘tests’
  • Ensure accessible formats are available.
  • Offer alternative ways of carrying out different recruitment processes
  • Provide equipment where requested.
  • Give candidates a telephone number or email address to contact us with any queries throughout the process. 

Everyone works towards the same goal. So no matter your background, someone is always willing to help.
