Lead the full engineering scope of capital projects and site modifications-from conceptual design through detailed engineering, procurement support, construction oversight, and startup-applying first-principles thermodynamics, reaction kinetics, fluid mechanics, and materials science to optimize pressure leach autoclaves, calciners, pressure filters, crystallizers, slurry pumps, and solids handling systems. This role owns the engineering deliverables that ensure inherent safety, mechanical integrity, and long-term reliability of assets converting spodumene concentrate to battery-grade lithium hydroxide in a fast-paced and innovative environment while directly supporting the Maintenance, Reliability, Process Controls, and Process Safety teams.
