Founded with a bold mission: to accelerate Europe’s sustainability goals by cutting household gas use at scale.

🌍 Senior Mobile Engineer (React Native)

The tech isn’t just efficient — it’s smart. Using machine learning, the system adapts to each home automatically, optimising energy use for maximum efficiency. And unlike clunky alternatives, it integrates seamlessly into existing setups, making adoption simple and fast.

With fresh funding secured in 2024 and a target to reach over a million households by 2030, the team is scaling quickly — and looking for a Senior Mobile Engineer to play a key role.
