About The Role

We are seeking a highly organised and detail-oriented Finance / HR Generalist to join our team. This role will provide critical support across both finance and HR functions, covering everything from credit control to payroll administration and employee onboarding.

This is a varied position, ideal for someone who thrives in a dynamic environment, enjoys working with both numbers and people, and is comfortable interacting with senior stakeholders as well as managing day-to-day operational tasks. Prior experience in finance or HR is not required - we welcome applications from career changers and return-to-work candidates. This is a part-time role, however, could flex up to full time if that suited the right candidate.

Please note this is a remote role, however there is the opportunity to travel to our custom designed offices in central London and take part in our regular team get togethers.
