Vertical ion-exchange tech for critical metals
Kunin Technologies is revolutionizing the critical mineral supply chain by implementing advanced separation systems with traditional unit operations to capture value from overlooked resources. Ore grades are falling globally, and conventional extraction leaves recoverable metal in material that mines and refineries write off as waste. Tailings, effluents, and legacy sites hold real value that existing separation technology can't reach economically.
Utilizing Kunin Technologies' proprietary mass manufacturable nano-separation systems, significantly more value can be produced from each resource, reducing waste, and unlocking domestic critical mineral production. Kunin is developing metal recovery flowsheets and reprocessing facilities from operating refinery effluents, decades-old tailings stockpiles, and even centuries-old Superfund sites.
Kunin is a team of process engineers, polymer scientists, and organic chemists with a 10k sq. ft. hydrometallurgical and organic synthesis lab in Chattanooga, TN. Kunin is pushing forward metal recovery projects across scandium, gallium, germanium, copper, cobalt, rhodium, and gold.
To achieve metal abundance, humanity must bring separation science down its own Moore's Law: fix the idiot cost index for micro and nano scale separation materials. This requires mass manufacturing novel ion-exchange media form factors which previously struggled from high costs.
You run the hydrometallurgical testwork that decides whether a Kunin project survives its next stage gate. Working under the Principal Hydrometallurgist, you turn a feed sample and a question into a test program, execute it in Kunin's Chattanooga laboratory or at a partner laboratory, and report a result the engineering team can design from. This includes:
Planning and executing bench-scale hydrometallurgical testwork: leaching, solid-liquid separation, ion exchange, solvent extraction, precipitation, and crystallization.
Preparing and characterizing samples: sub-sampling, head assays, size distributions, and the chain of custody that keeps a result defensible.
Closing mass balances on every test and flagging the ones that do not close before they reach a report.
Operating and maintaining laboratory equipment: reactors, columns, filters, mixer-settlers, and the analytical instruments the program depends on.
Writing test procedures, maintaining laboratory records, and producing the data packages behind stage-gate reports.
Supporting pilot campaigns on site and at partner facilities, including shift coverage during continuous runs.
Bachelor's degree in metallurgical, chemical, or mineral processing engineering and 2 to 6 years of hydrometallurgical testwork.
Experimentalist fluent in leach, ion exchange, and solvent extraction bench testing with careful control of pH, temperature, and reagent addition.
Skilled in laboratory data handling: mass balances, recovery calculations, and clean spreadsheets or scripts that someone else can audit.
Comfortable with analytical techniques (ICP, titration, XRD) and knows when a number should not be trusted.
Excited about working hard to push projects farther, faster in an early-stage startup environment with extreme autonomy, opportunity, and high expectations.
Team player who keeps the laboratory safe, the records complete, and the Principal Hydrometallurgist informed.
Must be willing to relocate to Chattanooga, TN and available to travel to partner sites and laboratories in the United States and Canada for sampling and pilot campaigns. Relocation support will be provided.
Extended hours and weekends frequently required to support critical project milestones.
Chattanooga is more beautiful than expected, and Tennessee has no income tax.
Kunin will do whatever it can to secure work authorization for the right candidate.

Vertical ion-exchange tech for critical metals
Kunin Technologies focuses on recovering critical metals using vertically integrated ion-exchange technology. It targets by-product critical metals and promotes domestic, US-based mineral processing, aiming to rebuild American ion-exchange capability. The company’s technology uses ion-exchange processes to selectively capture and recover metals from industrial streams, enabling purification and recovery of critical metals within the U.S. infrastructure. Across competitors, Kunin differentiates itself by its emphasis on vertical integration, domestic manufacturing, and a narrative directed at industrial and policy stakeholders that highlights the offshoring of mineral production and the need to revitalize domestic capabilities. Its goal is to be the leader in American critical metals by providing the technology and capability to recover these metals domestically, reducing reliance on foreign supply chains.
