Senior Pensions Administrator

About us

MI5 keeps the country safe from serious threats like terrorism and attempts by states to harm the UK, its people and way of life. We carry out investigations by obtaining, analysing and assessing intelligence, and then work with a range of partners, including MI6 and GCHQ to disrupt these threats. Through our protective security arm, we provide advice and guidance to government, businesses and other organisations about how to keep themselves safe. A role in MI5 means youll do unique and challenging work in a supportive and encouraging environment, making a real difference to UK national security.

Flexible working: due to the sensitive nature of the work, this is an office-based role with little to no opportunities for home working. We recognise the importance of a good work-life balance and offer part-time and compressed hours, with flexibility around start and finish times.

The role

As a Senior Pensions Administrator, youll help oversee our processes and support your colleagues as a subject matter expert. Youll balance high-volume casework with training and mentoring a growing team as you bring your expertise to our busy department. Working at pace, youll maintain quality and ensure our processes and systems run smoothly.

Day-to-day, youll be taking on project work, supporting with problem-solving, handling complaints and carrying out extensive quality checking. So, multi-tasking is key as youll be balancing your own workload alongside your teams. Youll answer queries from, and give advice to, pay teams and provide insights and guidance to senior leaders.

Youll also collaborate with colleagues throughout the UKs Intelligence Services and build relationships with external partners. Everything you do will contribute to supporting the growth of the department, from helping your team improve their skills and knowledge, to using your experience to come up with ideas for continuous improvement.

This is an opportunity to take ownership of a high impact role that blends operational excellence with transformation leadership. You will shape the future direction of remedy and project management, strengthen governance standards, and play a pivotal role in delivering sustainable change across the pension function.

About you

Youll bring existing knowledge about, and experience working in, pensions and have a minimum of 2 years experience in a similar role or sector. This will be supported by line management experience. Youll also need a minimum of 2 GCSEs at Grade 4/C or above in maths and English language (or an equivalent Level 2 qualification). Importantly, youll be an adaptable, organised leader with a focus on wellbeing.

Comfortable with numbers, youll have keen attention to detail and be able to check calculations and spot errors with ease. Youll also be a confident communicator able to adjust your style depending on whether youre supporting your team, building external relationships, or presenting to senior leaders.

Whether youre managing complex retirement cases, identifying solutions or managing stakeholders, youll be organised and balance target-driven performance with empathy. And of course, youll be IT systems literate.
