• Working in Xero and Excel or Google Sheets on a range of client files
• Responding to client queries and keeping client records up to date
• Using AI tools to speed up reviews, reconciliations and reporting
• Helping us build and document small automations and spreadsheet tools that remove manual work

• Solid grasp of accounting fundamentals
• Strong attention to detail and accuracy
• Strong written English and good communication skills
• Proficiency in Excel
• Ability to work independently and reliably in a remote environment

Advantageous
