Embedded Software Engineer

Our mission is to move humanity off of fossil fuel heating. 20% of US global warming emissions come from homes (thats more than cars!). The largest driver of home emissions is burning fossil fuels for heat. To stop climate change over 80M US homes need to transition from combustion to efficient electric heat pumps over the coming decades.

We believe for this to happen the world needs fantastic products that are easy to purchase. Todays heat pumps lack great design make limited use of software and are difficult and stressful to adopt. We are building a next generation beautifully designed AI optimized home heating and cooling system that is 10x better than what is on the market today.
