About Limejump
Optimising a 100% renewable energy future is our vision.

Limejump is a technology platform that manages a large renewable energy network. Our portfolio delivers clean energy to businesses and homes, using renewables and stored energy when it’s needed to meet demand.

We connect and manage 100% renewable energy through the intelligent control of renewable generators, such as wind turbines and solar panels. We work closely with renewable asset owners, buying their energy and then selling it onto the UK’s grid, giving them simple access to the power market. But, the sun isn’t always shining and the wind isn’t always blowing. We must therefore capture energy for times when there is high demand. By harnessing big data and renewable technology, we accelerate the UK’s transition to net zero carbon emissions.

The Role
As a Data Scientist at Limejump, you will be responsible for applying advanced analytics, data science and machine learning to develop market leading energy forecasting solutions, real-time control, and business insights for Limejump.

You will work with a dynamic team in a rapidly growing technology company at the forefront of disrupting an established industry, from our London office.
