Job description

My client is an early-stage rare mineral extraction company focused on developing innovative, efficient hydrometallurgical technologies to recover critical metals from mineral resources and next-generation, high-efficiency leaching technology designed for sustainable and scalable copper extraction.

They are looking for a highly analytical and driven Hydrometallurgist / Chemist to support the development, optimization, and scaling of hydrometallurgical chemical processes for mineral extraction, purification, and refinement.

This is an opportunity to join a high-growth organization and play a key role in advancing critical mineral processing from development through commercial production.

Responsibilities:

• Chemistry & Experimental Design: Develop hypotheses and laboratory test programs to solve priority chemistry questions, using aqueous chemistry and thermodynamic tools such as OLI and HSC.
• Process Development: Define chemistry requirements, operating windows, and process inputs to support mineral extraction, separation, purification, and optimization.
• Scale-Up & Troubleshooting: Support the transition from laboratory to pilot and commercial scale while troubleshooting chemical processing issues and providing technical support.
• Materials & Analytical Analysis: Apply XRD, XRF, ICP-OES, ICP-MS, SEM, and other analytical techniques while ensuring appropriate QA/QC, sample handling, and analytical methods.
• R&D & Technical Reporting: Develop novel reagents and processing methods, analyze results, and produce clear, traceable technical reports with actionable recommendations.

Qualifications:

• 3+ years of experience in analytical chemistry, aqueous chemistry, hydrometallurgy, experimental design, or related chemical-process development.
• M.S. or PhD in metallurgical engineering, chemical engineering, or any related field.
• Deep understanding of solvent extraction, ion exchange, electrowinning, electrorefining, transition metal chemistry, and / or materials characterization for copper applications.

***Must be willing and able to travel up to 25% of the time. This includes domestic travel within the United States and potential international travel.***
