Full Stack Engineer / Technical Lead (m/w/d) in ClimateTech

Why Now?

Buildings are the largest energy consumers in Europe, making them CO₂ monsters. They account for 40% of our energy usage, causing 36% of all EU CO₂ emissions. That's why the decarbonization of buildings is essential for a sustainable future.

Our Goal?

Becoming Europe’s insulation champion and insulate 1 million houses over the next 10 years! Now is your chance to be part of our vision. Join us in building a market-leading company in the climate sector. Unf*ck the planet with us and actively contribute to slashing CO₂ emissions from buildings.
