Equipment Design Engineer
Limelight Steel is on a mission to eliminate emissions from iron and steelmaking and build a brighter future. 8% of global CO2 emissions come from current fossil-based steelmaking processes - the largest source of industrial emissions today. Limelight Steel's electrified ironmaking technology has the potential to eliminate those emissions, significantly reduce energy use, and produce iron for cheaper than fossil-based methods.
