This role will report to the CFO and play a crucial role in the day-to-day financial operations of the company. This role will entail preparation of financial reports, month-end processes, and ensuring compliance with relevant accounting standards. You will be working closely with the business to assist with day-to-day finance management and identifying any commercial risks or opportunities to improve the business’ position.

  • Act as the first point of contact for technical accounting and financial reporting
  • Perform balance sheet and inter-company reconciliations to ensure integrity of the general ledger and financial records
  • Review monthly VAT returns and liaise with tax to provide necessary reporting
  • Manage and develop the financial reporting team, promoting high standards and reviewing their work as necessary
  • Provide support in the preparation of budgets and forecasts
  • Drive continuous process innovation to improve reporting accuracy, strengthen controls and improve efficiency
What you'll need

The reason why we don't advertise is because we honestly have a degree of flexibility and would never want salary to be a reason why someone doesn't apply to Octopus - what's more important to us is finding the right fit!
