Job Description

Experienced Office Administrator

Nottingham | Full-time or part-time | On-site | £28,000–£30,000 FTE plus bonus and benefits

Promethean Particles is looking for an experienced Office Administrator to keep our Nottingham office and essential administrative processes organised, accurate and running smoothly.

The position can be full‑time or part‑time - for example, approximately five hours a day, five days a week. In either case, the role will be based on‑site in Nottingham.

This is a hands‑on role for someone who already knows how to operate effectively in a professional office environment. You will be equally comfortable producing Board minutes and professional documents, organising company records, ordering lunch for a meeting or dealing with something practical that needs attention around the office.

You won’t need to know our business from day one, but you should already have the practical skills and judgement to take ownership of the role without needing to be taught the fundamentals of office administration.

What you’ll be doing

• Preparing, formatting, proofreading and managing professional documents.
• Taking accurate minutes at Board and leadership meetings and tracking agreed actions.
• Organising shared folders, templates, company records and other business information.
• Using Word, Excel and Outlook for everyday administration and document management.
• Providing administrative support to the CEO and wider leadership team.
• Coordinating meetings, diaries, travel, visitors and company events.
• Arranging refreshments, lunches and practical requirements for meetings and visitors.
• Managing incoming calls, post, deliveries and office supplies.
• Liaising with suppliers and facilities providers.
• Helping to keep the office and reception presentable, including dealing personally with small tasks when needed.
• Tidying up existing information and identifying practical ways to improve administrative processes.

What we’re looking for

You will need:

• Previous experience in an Office Administrator, Business Support, Team Assistant, Executive Assistant or comparable role.
• The confidence to take ownership of day‑to‑day office administration with limited supervision.
• Practical experience of taking clear, accurate meeting minutes.
• Strong Word skills, including formatting and tidying professional documents.
• The ability to use Excel accurately for straightforward administrative tasks and record keeping.
• Experience organising electronic documents, folders and records.
• Excellent attention to detail, including spelling, grammar, formatting and data accuracy.
• Strong organisational skills and the ability to manage several priorities.
• A practical, helpful attitude and a willingness to deal with whatever needs doing to keep the office running well.
• A friendly, professional and dependable approach.
• Full and unrestricted authorisation to work in the UK.
• Experience supporting senior leaders would be useful, but isn’t essential.

About Promethean Particles

Promethean Particles develops advanced materials that can help address major sustainability challenges, including carbon capture and clean energy.

As the company grows, you will have genuine ownership of how the office and its administrative processes operate. This is an opportunity to become a trusted and important member of an innovative business doing meaningful work.

• Annual performance bonus
• Company pension
• Private medical insurance
• Group life insurance

Salary and benefits will be provided on a pro‑rata basis for part‑time employees where applicable.

The interview process will include a short, practical Word and Excel task based on the type of everyday administration involved in the role.

If you are an experienced administrator who enjoys producing accurate work, organising information and taking pride in keeping an office running properly, we’d like to hear from you.

Equal opportunities

Promethean Particles is committed to equal opportunities in employment. We encourage every employee to bring their whole self to work, enabling them to contribute more and enjoy a more fulfilling career.
