Position Overview

CSI Group is seeking a highly experienced and detail-oriented Assistant Controller to serve as the right hand to the Head of Finance. This is a high-impact, in-office role for a seasoned accounting professional who is ready to own the month-end and year-end close process, drive the day-to-day integrity of the general ledger, and lead meaningful operational improvements across accounts payable and accounts receivable.

This person will work directly with the Head of Finance and will have regular exposure to senior leadership, including the CEOs. Over time, the Assistant Controller will build and manage a team that includes an A/R Specialist, an A/P Specialist, and a Property Accountant. The expectation is that within one year, CSI Group’s books will be maintained to full audit-ready standards, and this person will be instrumental in getting us there.
