# Design Engineer

Since early 2024, we've gone from 0 to over 900 customers, succeeding where many have tried and failed before. We have a big mission: to make it wildly easier and more profitable to run and grow a renewables installation business, and through that to make a real dent in the world's carbon emissions and a far better experience for homeowners. We're now looking for a Design Engineer who wants to design & ship exceptional outcomes for users. Most of our product is a front end over hard physics (heat-loss calculations, hydronic design, LiDAR floor plans, compliance that has to be right), used by installers on a phone, with no signal, in a hurry. Making that feel simple is a design problem and an engineering problem at the same time, and this role sits right on that seam. About Spruce Almost 20% of the UK's carbon emissions comes from heating homes - there's simply no way to reach net zero without phasing out gas and oil boilers. Right now the only serious alternative is heat pumps, with their almost-magical ability to turn 1 kW of electricity into 3-5 kW of heat (). But the heat pump installation journey is slow, inefficient, and just so painful. This makes it hard for existing install
