RHI Magnesita GmbH manufactures high-grade refractory products, systems, and services for industrial processes operating at temperatures exceeding 2000°C. The company operates 35 main production and raw materials sites, maintains over 70 sales offices, and ships to customers in 180 countries across steel, cement, glass, lime, non-ferrous metals, energy, environmental, and chemical industries.
Founded in 1834 as a fireclay factory and formed through the October 2017 merger of Austrian RHI with Brazilian Magnesita, the company is headquartered in Vienna and listed on the London Stock Exchange as a FTSE 250 constituent. The technical challenge underlying the business is materials engineering at scale: designing, manufacturing, and delivering ceramics and composites that maintain structural integrity and thermal performance in the most demanding industrial furnaces and reactors. This requires control over raw material sourcing, firing processes, and system-level integration across diverse customer applications.
RHI Magnesita operates under a 4PRO strategy emphasizing innovation, safety, and sustainability. Engineering roles support both product development in refractory materials science and the integration of refractory systems into customer processes - work that spans materials characterization, thermal modeling, process control, and field deployment across global operations.
