Join a company that is passionately committed to the pursuit of a better world through positive change. With more than 70 years of business and technical expertise in mining , energy , and infrastructure ,our 10,000 colleagues in 150 countries tirelessly work toward bettering the industries in which we operate. With practical solutions that are safe, innovative and sustainable, we think globally while acting locally.Are you looking for an opportunity to join a diverse group of professionals who are committed to remaining exceptional? We look forward to hearing from you.

If it isn't grown, it's mined. Our mining and metals teams help our clients to safely and sustainably mine the minerals and metals used in our everyday lives. Want to play a part of innovating and optimizing the mining life cycle on greenfield and brownfield facilities?

We have an exciting opening for an experienced Senior Minerals Processing Engineer to join our team on a full-time basis. You will be given the opportunity to work in collaboration with both internal staff and our clients to provide effective execution, coordination and supervision of mining, minerals processing and geometallurgical laboratory and fieldwork.

You will become involved in a wide variety of Projects - from brownfield optimisation, expansion studies to greenfield.

This role will involve execution, coordination and supervision of mining, minerals processing and geometallurgical laboratory and site/fieldwork, execution of technical reports and engineering documentation, identification of project opportunities, mathematical modelling, simulation (in comminution and flotation areas extended to understanding and integration with drill and blast, throughput forecasting and geometallurgy), field test work for integration and optimisation of existing mining and minerals processing operations, expansion studies and greenfield - design projects.

We are looking for someone with good communication skills as writing technical reports and completion of engineering documentation for our customers will be a key part of this role.
