Nice To Haves

• Familiarity with rare earth separation techniques (e.g., solvent extraction, precipitation) preferred.
• Working knowledge of PFDs/P&IDs and process control systems (SCADA/DCS) is a plus.

Responsibilities

• Design and execute experiments for rare earth leaching, solvent extraction, and purification.
• Translate bench-scale work into pilot-scale operations, supporting scale-up and process optimization.
• Operate and support pilot plant systems, including test planning, data collection, and troubleshooting.
• Perform mass balances and analyze process data to improve recoveries, efficiency, and product quality.
• Develop technical documentation (SOPs, PFDs, test reports) to support pilot operations and scale-up.
• Collaborate with engineering and operations teams to advance process design and commercialization.
• Support safety programs, including PHAs and compliance with environmental and operational standards.
