at Limelight Steel

🏢 About Limelight Steel

Limelight Steel is revolutionizing steelmaking by developing clean electric laser furnace technology to dramatically cut industrial CO2 emissions. Unlike traditional steel companies, they're at the forefront of sustainable industrial innovation, combining advanced optics, high-temperature engineering, and environmental impact. Working here means contributing directly to decarbonizing a major global industry while pushing the boundaries of thermal and mechanical engineering.

About This Role

As Project Engineer, you'll lead the design of molten-metal hardware for next-generation laser furnaces, ensuring mechanical integrity and safety under extreme conditions. You'll drive integration of optics, sensors, and high-temperature structures while establishing engineering standards for rapid yet rigorous hardware development. This role is impactful because your technical leadership will directly enable scalable, clean steel production technology.

💡 A Day in the Life

A typical day involves leading design reviews for molten-metal hardware components, collaborating with optics and sensor specialists on integration challenges, and analyzing thermal modeling results to guide design decisions. You'll mentor equipment design engineers on mechanical integrity considerations while developing validation protocols that ensure safety in extreme operating conditions. The role balances hands-on technical problem-solving with establishing engineering standards for the team's rapid development pace.
