Research Engineer in Ironmaking Digitalization

ArcelorMittal is the world's largest steel producer. We use the most innovative technologies to create the steels tomorrow's world will be made of. Every day over 125,000 of our talented people, located in over 60 countries, push the boundaries of digitalization, and use advanced technologies to create a stronger, faster, and smarter world. To help make this possible, they know they can depend on the support and training that a company of our scope and scale can provide.

Comprising 1,650 researchers spread across 14 Research Centres around the world, our Global R&D team aims to continuously improve the quality of steel and its manufacturing processes. This involves investigating and developing disruptive technologies, reducing the carbon footprint of steel, and optimizing costs while maintaining uncompromising quality. The team's strong multicultural diversity, with over 30 nationalities, offers international experience and makes it possible to meet global needs.

Within this context, you will be working for Maizières Process research centre located in Maizières-lès-Metz (France) which main mission is to contribute to ArcelorMittal's production lines competitiveness and sustainability by the development or improvement of innovative processes or processing routes (from Ironmaking to metallic coating). The objectives of the laboratory are answering the needs of our operations (mineral processing, steel upstream operations, steel downstream operations, product quality, transversal issues). We are able to offer new technologies, standard solutions, technical assistances and knowledge building.

As the world's leading steel producer, ArcelorMittal has a responsibility to be at the forefront of a transition in steel that achieves the goals of the Paris Agreement. Steel industry accounts for some 7-9% of global carbon emissions today. Iron ore reduction is where the vast majority of carbon emissions come from in the steel industry. The carbon challenge in the coming decades is therefore in the transformation of the way in which we turn iron ore into steel. ArcelorMittal has a strategy to reduce its carbon footprint based on the decarbonisation of the existing blast furnaces and by the erection of new direct reduction plants.

Your role

As a Research Engineer in the Primary department of the ArcelorMittal Maizières Process Lab, you will lead R&D projects focused on ironmaking process optimization and decarbonization.
