About GO2 Mechanical

GO2 Mechanical is an Ontario mechanical contractor serving commercial, industrial, institutional, and high-rise clients. We handle HVAC and refrigeration, plumbing and piping, welding and custom fabrication, and water treatment, from design through installation and ongoing maintenance.

We're a lean, growing team, and the office is the hub that keeps our technicians, clients and paperwork moving.

The Role

We're looking for an organized, people-first Office Manager to run the day-to-day of our office. You'll be the first point of contact for our clients, keep our technicians scheduled and dispatched, and stay on top of invoicing, receivables and payables. If you like being the person who keeps everything on track, this role is for you.

What You'll Do

- Answer client calls and emails, book service requests and keep clients updated on job status
- Schedule and dispatch our team of technicians, adjusting the day as priorities change
- Organize and maintain company documentation: work orders, quotes, contracts, permits and job files
- Issue invoices and track accounts receivable, following up on outstanding balances
- Track accounts payable, manage supplier bills and keep vendor records current
- Work in our in-house business software for invoicing, estimating and job tracking (it syncs to QuickBooks)
- Support the owners with general administration and help improve office processes as we grow

What You Bring
- Confidence to join a small, nimble, and growing company




- 3+ years of office administration experience (any industry)
- Comfort with billing, receivables and payables
- Clear, professional phone and email communication with clients
- Strong organization and the ability to juggle scheduling, calls and paperwork in the same day
- Confidence with computers and willingness to learn new software
- Basic QuickBooks familiarity is helpful but not required; our system handles most of the accounting work

Nice to have: experience in plumbing, HVAC, construction or another trade, or with technician scheduling and dispatch. Experience using AI tools (such as ChatGPT or Claude) to work faster, draft emails, organize information or streamline admin tasks is a valuable asset. Optional 4-day workweek: Want a three-day weekend, every weekend? This role can be worked as a four-day week. Prefer a standard Monday-to-Friday? That's also an option.

Why Join Us

- Optional 4-day workweek for a better work-life balance and a three-day weekend
- Competitive pay of $22–$30+/hour, based on experience and tenure
- Stable, full time role at a growing contractor with commercial, industrial, and high-rise clients
- A small team where your work is visible and valued
- Room to shape how the office runs as we grow
