About us: ChemFinity Technologies is building critical mineral recovery systems to produce over 20 minerals from waste and mining feedstocks at low cost, using our proprietary, high-performance, high-durability sorbent filters. Our team’s mission is to produce these minerals in ways that are cheaper, cleaner, and more accessible than existing methods such as high-temperature smelting, starting with precious metals like platinum. Spun out of UC Berkeley in late 2022 and based in New York City, ChemFinity is backed by top-tier investor firms and over 10 top government and grant agencies, such as Bill Gates’s Breakthrough Energy Fellows, the U.S. Department of Energy, ARPA-E, and the U.S. EPA. ChemFinity has been recognized as top innovators in the critical minerals sector by the World Economic Forum, Forbes, and Conservation X Labs. What you will do: ChemFinity seeks an industry-experienced hydrometallurgist who will lead the development, optimization, and scale-up of hydrometallurgical processes that are used in tandem with our sorbent filter systems. In this role you will work creatively and hands-on with our research team of chemists and engineers, co-founders, and external partners as we build early pilots and grow from the lab to industrial scale. Key responsibilities include: <ul><li>Lead the hands-on design, development, and construction of leaching and hydrometallurgical unit operations in our mineral processing systems. </li></ul><ul><li>Optimize the extraction conditions of various minerals of interest (e.g., platinum-group metals, gold, rare earth elements, base metals) from various waste and mining feedstocks (e.g., catalytic converters, e-waste, mine tailings). </li></ul><ul><li>Scale the hydrometallurgical and leaching processes from the lab to pilot scale and beyond. </li></ul><ul><li>Collaborate closely with our chemistry team to optimize sorbent performance in hydrometallurgical conditions. </li></ul><ul><li>Work with our engineering team to integrate the processes you lead into our refining systems and with external partners (e.g., EPCs) to design, construct, and deploy larger-scale systems. </li></ul><ul><li>Prepare and manage comprehensive documentation, including flowsheets, equipment and process design criteria, technical reports, and standard operating procedures.  </li></ul><ul><li>Perform full-time hands-on work on-site at our Brooklyn facility. </li></ul>What you will bring: <ul><li>Bachelor’s degree (or higher) in metallurgy, chemical engineering, mining engineering, chemistry, or other closely related field. </li></ul><ul><li>5+ years of industry experience in mineral processing, metal leaching and recovery, and/or other closely related technical developments or operations.
