We are seeking to fill a newly created role of Assistant Controller.
Reporting to the Financial Controller, the Assistant Controller will play a key role in accounting operations, financial reporting, project financial oversight, internal controls and continuous improvement, while developing an in-depth understanding of Tatham’s project-based consulting engineering business and ERP system.
During the first year, the Assistant Controller will carry an assigned portfolio of client billings alongside their core accounting responsibilities. This hands-on exposure will develop a strong understanding of Tatham’s projects, clients, ERP and project accounting processes. As that knowledge develops, responsibilities will increasingly shift toward financial reporting, budgeting, project financial monitoring, internal controls, and process improvement and oversight of accounting activities.
There is an option for this to be a hybrid role with a minimum of three days in office per week. The successful candidate can be based out of our Barrie, Collingwood, or Orillia office.
