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 steelmaking processes - the largest source of industrial emissions.

We are building furnaces to produce clean steel that will form the foundations of a fossil-fuel-free world.

We are a startup in Oakland, CA, backed by industry-leading climate tech investors, looking to grow our team. Our people are the foundation of our company, and we are committed to building a diverse and courageous team of people motivated to make a positive impact on the world.
