Our Business

geo is changing the way the world uses energy. Our solutions have already saved homes in the UK, Netherlands and Nordics more than 30 terawatt hours of energy. Today, we have more than 6 million smart energy devices deployed in homes and we supply managed energy data services to more than half a million homes across Europe. We’ve used those capabilities plus our deep learning algorithms and data analytics to halve household energy consumption and slash carbon emissions. In 2022, we’re taking those capabilities to the next level, with a mission to save more than 20 million tonnes of CO2 and more than £3Bn of net savings for UK homes over the next 5 years.


Our capabilities and developments range from the hardware and firmware that powers the devices to the algorithms that power the insights we deliver via those devices, through to sophisticated control systems that predict and manage EV charging, energy storage, home energy generation and even household white goods. Underpinning this is our expertise in smart energy monitoring, load disaggregation, anomaly detection, heating control systems, load prediction and optimisation.


We are looking for a DevOps Engineer to join our 80-strong company and to be part of a uniquely-talented team of developers and data scientists delivering that mission.
