About Dexotech

Dexotech provides advanced engineering, diagnostic, and forensic services to the power industry. We support utilities, industrial clients, contractors, and infrastructure owners through every stage of the power system lifecycle.

Our team values technical excellence, accountability, client care, and practical execution. As we continue to grow, we are strengthening our financial systems, controls, and reporting to support a larger and increasingly complex business.

The Opportunity

We are seeking an experienced Part-Time Controller / Senior Bookkeeper to take ownership of Dexotech's day-to-day accounting function and provide practical financial oversight to management.

This is a hands-on role. The successful candidate will be comfortable processing and reviewing transactions while also operating at the controller level—closing the books, maintaining financial controls, preparing management reporting, monitoring cash flow, and identifying issues before they become problems.

You will work closely with the Managing Director and our Office Manager. The Office Manager will support administrative processes and documentation, while you will be responsible for the accuracy, completeness, and integrity of the company's financial records and reporting.

This is a part-time hybrid position, approximately 16–24 hours per week. Attendance at our Etobicoke office approximately one day per week is expected, with additional attendance occasionally required.
