Commercial VRF Commissioning & Controls Specialist
Job Description
Job DescriptionShape the climate of the Bay Area with DMG (an Ambient Company)
Start your morning in Oakland, coffee in hand, reviewing a new build’s plans before heading to a customer site.

After lunch, you decipher a wiring schematic to resolve a controls issue on a commercial Daikin system. Before you wrap for the day, you submit startup documentation for warranty, update service reports, and touch base with the project team. That’s a typical day for a Commercial VRF Commissioning & Controls Specialist at DMG.
