About CELSA
We’re Europe’s leading producer of circular, low-emission steel and its largest circular supply chains. We recycle ferrous scrap into new steel through electric arc furnaces, one of the most energy-efficient steelmaking routes available. Founded as a family business near Barcelona in 1967, the Group today brings together ~5,000 people and produces 5.7 million tons of steel annually, made with ~95% recycled content and designed to be 100% recyclable
Our purpose extends beyond steel: making the cleanest way to produce it also the smartest – and data, analytics and artificial intelligence are central to that ambition.
We are now embedding AI into core steelmaking operations, moving beyond isolated experiments toward models integrated into how steel is produced, traded and optimized.
This role is suited to a hands-on builder who wants to see their work deployed in live operating environments, supporting furnace operators, metallurgists and traders
The Data Scientist can take models from concept to production in close collaboration with experts who understand steel’s physics, operations and economics. Working alongside our team, this role can help shape how the company makes decisions with data, building models that create operational and commercial impact.
What you’ll do
- Design, train and validate ML models for high-impact manufacturing, scrap, commercial and procurement use-cases
- Take models from prototype to production – feature pipelines, retraining, monitoring – deployed across cloud, edge and control-room
- Make models explainable and trusted: clear drivers, confidence levels, built for real adoption
- Partner with process experts and use-case owners so every m
