You know that shipping value to users is more important than using the absolute latest trendy library., • Empathetic: You understand that our users are working in high-stress healthcare environments. Reliability and usability matter., • Thrive in ambiguity: You dive into the unknown and work to bring people, ideas and problems together to form a clear cohesive plan

About Us Electron is a fast-growing tech company in the energy flexibility space. We’re working to transform how electricity grids work, as the need for electricity doubles and the increase in renewables continues to add pressure to the grid. We’re looking to bring more passionate people into our team to help us do this! In just a few years, we’ve gone from pilot projects in the UK to over 50% market share with full platform deployments, becoming the leading platform for flexibility markets.
