Software Engineer

Solo Energy presents an exciting opportunity for a Software Engineer (Server-side) to join an energetic, dynamic and innovative energy business.

Solo Energy is building the power plant of the future – the Virtual Power Plant. A decentralised and 100% renewable energy power plant driven by energy storage, blockchain and the people. We see a bright green future where electricity consumers are given the opportunity to participate in a socially responsible and environmentally friendly energy system, where they can buy, sell and trade energy within the community while also supporting the wider grid network and local renewable energy generators.

Our VPP software platform, FlexiGrid, controls and aggregates home batteries and electric vehicles to operate as a ‘Virtual Power Plant’, allowing energy suppliers to intelligently link energy storage to low‑cost renewable generation and therefore deliver affordable green energy to their customers.
