Job description: Solar PV Designer

Who We Are ⚡

At iHeat, we started by shaking up the boiler industry. Now we’re scaling fast in renewables with solar panels, battery storage, heat pumps, and EV chargers. We’re building a smarter, greener energy brand that homeowners can actually trust.

We’re not just another installer. We’ve built our own tech, systems, and in-house teams to take the stress out of home energy upgrades. Now we need a sharp designer to help power the next stage of our solar journey.
