Senior Process Engineer

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. Up to a 6x increase in critical mineral demand is expected by 2040, to meet the supplies needed for clean energy, defense, manufacturing, and other technology sectors. However, 80% of U.S. critical minerals already come from foreign sources, and 7% of greenhouse gas emissions come from mining. 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.
