Office Manager (maternity cover)



Organise our world and be trusted to do things your own way

Do you love keeping things organised and running smoothly? Are you happiest when people are relying on you to keep the world spinning? Does it excite you to be surrounded by people who love their work? Would you thrive in a company where you get to be your own boss?

If so, read on.

GrantTree is the coolest company you’ve probably never heard of. We’re a small and friendly workforce and we love our jobs. Our home is in the beautiful Treehouse workspace in Clerkenwell (a project we set up).

As our Office Manager, you will be central to the smooth running of the business. By fixing problems before anyone is affected, and by looking after the little things that matter a lot, you will enjoy being one of the stars of our company.

About you

  • You have proven experience as an office manager or in another administrative role

  • Your time-management, prioritisation and attention to detail are second-to-none

  • You like solving problems and are willing to get stuck into any task, big or small

  • You are organized, unflappable and have a sparkling approach to people

  • You have shown you can build relationships and handle difficult situations

  • You are comfortable working independently - you will be an important part of GrantTree, but as a “team of one” you will need to organise all your work for yourself

A typical day

We know that a great Office Manager is the glue that holds an organisation together. You look after the stuff most people don’t think about, that helps us all be happier and more effective at work. This includes:

  • Maintaining and improving the layout of our workspace

  • Making sure the office is well stocked and all the equipment is in working order

  • Dealing with day-to-day finances, such as paying suppliers and salaries, liaising with our external book-keepers, and being the go-to person for queries on pensions and benefits

  • Ensuring our company records are up-to-date, including looking after joiner and leaver admin

  • Organising birthday cakes, company socials and other fun activities

  • Keeping an ear to the ground to figure out any other things that could make working at GrantTree better

And let’s not forget the Office Manager magic - that special something that goes beyond getting stuff done and helps bring the company together.

About us

GrantTree was founded 6 years ago and employs 27 people. In our culture everyone has the freedom, power and trust to do great work. We call this open culture. It’s been successful for us so far, although it's not for everyone (we suggest you check out our GlassDoor reviews).


We believe that people should be rewarded fairly for the work they do. At GrantTree there is transparency over salaries and the way we work them out. For this role, this is likely to be around £35k. We also have an annual profit sharing scheme for the whole team.

Aside from money, we offer a great environment where you can be yourself. We want you to develop your skills and fulfil your potential. We have a flexible approach to working, and some of our staff work remotely most of the time. You can also take up to 6 weeks as holiday.

Equal opportunities

Teams are stronger when they have a diverse range of people. Applications are welcomed from everyone, regardless of the categories they place themselves into. We also encourage talented ‘square pegs’, who don’t neatly fit into the person specification, to apply.

NB: This maternity cover contract runs to at least the end of October.
