Hydrometallurgist
About The Position
ChemFinity Technologies is building critical mineral recovery systems to produce over 30 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. 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. Environmental Protection Agency. ChemFinity has been recognized as top innovators in the critical minerals sector by the World Economic Forum, Forbes, and Conservation X Labs.
Requirements
- Bachelor’s degree (or higher) in metallurgy, mining engineering, geochemistry, or other closely related field.
- At least 3+ years of industry experience in mineral processing, metal leaching and recovery, and/or other closely related technical developments or operations.
- Expertise in industry-standard hydrometallurgical techniques (e.g., leaching, purification processes), with hands-on experience optimizing process variables (e.g., reagent chemistry) for complex sources (e.g., e-waste, mine tailings).
- Practical understanding of industrial capabilities, constraints, and trade-offs to ensure technical and commercial viability of hydrometallurgical designs.
- An unwavering commitment to high safety standards and supportive work behavior.
Nice To Haves
- A Ph.D. is a plus.
- Experience with precious metal leaching, processing, and refining.
- Experience in startups or scaling technology from R&D to full-scale commercialization.
- Experience in developing pilot plant flowsheets, models, and unit operation designs.
- Experience in implementing the highest safety standards into scale-up operations.
- The desire to be in a dynamic startup environment and proactively use critical thinking to solve difficult but impactful challenges.
Responsibilities
- Design, develop, and test leaching and hydrometallurgical unit operations in our mineral processing systems.
- Optimize the extraction conditions of various minerals of interest (e.g., platinum-group metals, gold, rare earth elements, metalloids) from various customer and partner waste and mining feedstocks (e.g., catalytic converters, e-waste, mine tailings).
- Collaborate with our chemistry team to optimize sorbent processing in hydrometallurgical conditions.
- Work with our engineering team to integrate and scale the processes you develop into our refining systems from lab to pilot to demo scale.
- Prepare and manage documentation such as flowsheets, equipment and process design criteria, technical reports, and standard operating procedures.
- Perform full-time hands-on work on-site at our Brooklyn facility.
