**We are ERO**, a mining company born in the heart of Brazil that has grown to bring more strength and energy to the world — a strength that drives productive sectors and contributes to the development of different regions. Since 1979, when it began operations at the Caraíba unit, the company has been consolidating its presence in the Brazilian mining sector, expanding into the Xavantina gold mine and advancing the implementation of the Tucumã unit — which promises to become one of the country's main copper production hubs. Our growth is driven by exploration expertise, enabling us to extend the lifespan of our mines and advance new projects such as the Furnas Project in Pará. Our approach to mining is guided by solid values: care, courage, honesty, collaboration, and excellence. These principles are central to everything we do — from the mine floor to strategic decisions. They also guide how we support the growth of every individual at Ero. Our goal is clear: to be the best mining company in Brazil, and we know this is only possible by investing in the people who build this future with us every day. **Do you identify with this?** We are seeking a candidate to work as a **Mid-Level Process Engineer**, responsible for conducting process analyses and proposing improvements to optimize efficiency, reduce costs, and enhance operational performance.
