  • Support tax compliance and reporting by providing accurate schedules, reconciliations, and supporting documentation to internal stakeholders and/or external tax advisers
  • Lead automation and the effective utilisation of AI tools to improve reporting quality, streamline reconciliations, support variance analysis and commentary, and increase efficiency—while ensuring appropriate review and controls are maintained
  • Maintain and improve financial controls, including process documentation and continuous improvement of key control checks
  • Review work prepared by others (where applicable), providing quality assurance, guidance, and informal coaching to support high standards across the team
  • Identify, recommend, and implement process improvements to strengthen financial controls, reduce risk, and improve scalability
