About the Opportunity
Our client is a privately held, high-growth infrastructure company operating across North America and internationally. They develop and operate large-scale assets, and their operating portfolio is expanding rapidly.

As completed projects move from construction to operation, this Senior Accountant takes ownership of their financials. Reporting to the Manager of Accounting, you’ll act as a site-level controller for your assigned portfolio: owning the month-end close, key balance sheet areas and clear, decision-ready P&L; reporting. The work goes beyond a traditional property accounting seat, covering equipment, maintenance and operating costs, with a strong emphasis on variance analysis and forecasting.

This is not a rigid, legacy finance workplace. The team values people who are adaptable, ask why, and solve problems quickly. You’ll help automate processes, sharpen monthly variance analysis and explore practical uses of AI across the finance function, all while keeping a strong controls mindset.
