Job Details:

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 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.
