  • Review and strengthen financial controls, processes and systems so they can scale
  • Oversee the year-end audit, statutory reporting and tax compliance across entities
  • Support any fundraising, debt or M&A activity, including investor relations and due diligence
  • Manage and develop the finance team, and assess what the function will need long term

Qualifications

  • Qualified accountant (ACA, ACCA or CIMA) or equivalent
  • Previous CFO or senior Finance Director experience in a SaaS or technology business
  • Track record of board and investor reporting in a PE or VC-backed environment
