About us
MI5 safeguards the UK against threats such as terrorism, espionage, cyber and sabotage. We investigate suspect individuals and organisations in the UK to obtain, collate, analyse and assess secret intelligence relating to these threats. Alongside our British Intelligence partners, MI6 and GCHQ, we provide the UK government with the information they need to protect national security. At MI5, youâll enjoy varied and rewarding work in a supportive and encouraging environment that puts the emphasis on teamwork.
The Role
As a Senior Admin Officer youâll work as part of a large, multi-skilled research team, delivering analysis to support the vetting process across the UKâs Intelligence Services. Itâs a role where, once fully trained, youâll work with a high degree of autonomy and use your own judgement, all to support our mission to keep the UK safe.
Vetting is vitally important to what we do because it ensures that the people who have access to some of the UKâs most sensitive information can be trusted. Everyone who works within the UKâs Intelligence Services goes through vetting, so itâs crucial that our decision making is evidence-based, accurate and consistent. Thatâs where you come in.
Day to day, youâll complete research and analysis on a range of data that helps build a picture of someoneâs suitability to hold security clearance. Using a variety of tools and methods, which weâll train you in, youâll both find information and assess it, spotting links between different pieces of data as you drive your caseload forward. Once youâve finished your analysis, youâll write reports containing your findings, which will be used to support decision making by our Vetting Officers.
It's a fast-paced role, where youâll need to have a keen eye for detail, be able to prioritise your workload independently, and meet strict deadlines. Whether youâre at the beginning of your career, returning to work after a break, or are looking for a new challenge, this role has the potential to begin a career with the UKâs Intelligence Services where youâll be key to maintaining the integrity of one of our most crucial processes.
While this role is primarily within our vetting team, successful candidates may be offered an alternative admin role at the same level within another team, subject to business need.
About You
Youâll need either
- two GCSEs (or equivalent) in Maths and English Language at grades A*-C/9-4,
- or experience in an office environment working in an administrative role.
Youâll also:
- Be keen to learn, as this role includes an initial training period where youâll be brought up to speed on our research and analysis techniques.
- Be comfortable using your initiative and talking to a range of people.
- Have attention to detail, even when working to tight deadlines.
- Have great organisational skills.
Weâre interested in what makes you, you. Thereâs no one âtypeâ of person that weâre after. Whether you choose to work full time or part time, youâll feel part of a large, welcoming team where thereâs plenty of support and training on offer. If you have a disability or long-term health condition, just let us know if you need any adjustments made during the recruitment process or if you have any questions about how we can support you once youâre in-role.
Training and Development
Weâre committed to helping our people develop their skills and career by ensuring everyone gets the training and support they need to succeed. When you join us as a Senior Admin Officer, youâll begin a formal training and mentoring period that usually lasts around 3 months. This will equip you with all the knowledge and skills you need to undertake the role.
Following this period, youâll continue to draw on support and guidance from your colleagues. Youâll also get opportunities to attend a wide range of personal development and job specific courses. Whether through courses run by our own academy, or through knowledge sharing, youâll never stop learning. And after youâve completed two years in your role as Senior Admin Officer, youâll have the option to move to a different role anywhere within the organisation, either at the same level or via promotion if youâre ready.
Rewards and Benefits
Youâll receive a starting salary of ÂŁ27,751 - ÂŁ30,024 (dependent on location)
