Sales Applications Engineer (HVAC)

At Oxygen8, we’re driven by a simple mission: to make indoor spaces healthier and buildings more energy-efficient. Our 100% electric ventilation systems improve air quality, reduce carbon footprints, and help people feel safe and comfortable in the spaces where they live, work, and play.

Since 2019, we’ve grown from a single solution into a portfolio of flexible systems designed for how buildings are actually built and used. We value creativity, collaboration, and ownership – here, your ideas can shape solutions that make a real difference.

Working at Oxygen8 means joining a fast-moving, innovative team where problem-solving and continuous improvement are part of the culture. Our momentum has been recognized along the way: in 2025, we were named Vancouver’s #1 fastest-growing company, and in 2024, we earned Company of the Year – Scale from the BC Tech Association, ranked #1 in Clean Technology on the Deloitte Technology Fast 50, and #28 on the Deloitte Technology Fast 500.

About the Role

Location: remote across Canada or hybrid at one of our Toronto or Vancouver officesPosition type: full-time & permanent Compensation: $65,000 - $75,000

If you enjoy figuring out how things work, solving technical problems, and turning complex requirements into practical solutions, this could be a great opportunity for you.

As a Sales Applications Engineer, you’ll support customers across Canada and the United States, working with project requirements to help develop accurate, customized HVAC solutions. You’ll collaborate with customers and internal teams across Vancouver, Toronto, and Gaspé while building your knowledge of our products, HVAC applications, and industry standards.

This is not a traditional sales role and does not involve cold calling or HVAC system design. Previous HVAC experience isn’t required, though familiarity with HVAC, building systems, or a related technical industry would be an asset. What’s more important is your technical aptitude, curiosity, attention to detail, and willingness to learn. If you like solving problems and want to develop your expertise in a technical, customer-focused environment, we’d like to hear from you.
