Limelight Steel

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.

We are a startup in Oakland, CA, backed by industry‑leading climate tech investors, looking to grow our team. We are committed to building a diverse and courageous team of people motivated to make a positive impact on the world. We want to hire kind and supportive teammates who have the perseverance to achieve our audacious goal of decarbonizing steel.
