This role is ideal for someone who understands how processing plants actually run, but can also translate that practical knowledge into high-quality studies, flowsheets, trade-off analyses, and cost estimates.Requirements:Metallurgical, Mineral Processing: A Bachelor’s or Master’s degree in Metallurgical Engineering, Mineral Processing, Chemical Engineering, or a closely related discipline only if they understand mining.Industry Experience: 5 to 8 years of experience across mineral processing operations and/or technical consulting, with practical exposure to concentrators, hydrometallurgical plants, comminution circuits, flotation, leaching, dewatering, tailings, or related processing systems.Operational Understanding: Direct plant or site experience is strongly preferred. We want someone who understands the realities of throughput, recovery, availability, reagent use, sampling, maintenance constraints, and metallurgical accounting, not just the theory.Study Expertise: Experience contributing to or managing processing inputs for PEA, PFS, or Feasibility Studies, including flowsheet development, mass and water balances, equipment sizing, process design criteria, Capex/Opex estimation, and trade-off studies.Technical Capability: Strong command of mineral processing calculations, testwork interpretation, process modeling, and engineering documentation. Experience with tools such as JKSimMet, METSIM, SysCAD, HSC Chemistry, Bruno, AggFlow, or similar platforms is preferred.Cross-Functional Collaboration: Ability to work closely with mining engineers, geologists, tailings engineers, environmental specialists, vendors, and project managers to develop practical, defensible technical study outputs.Communication Skills: Strong written and verbal communication skills, with the ability to prepare technical reports, explain assumptions clearly, and present recommendations to both technical and non-technical stakeholders.Work Authorization: Must be legally authorized to work in the United States on a permanent basis.
