About the job

Requirements
  • Have 10 or more years of process engineering experience, including both flowsheet development and detailed engineering.
  • Be capable of developing a hydrometallurgical process from paper design through laboratory work, piloting, construction, and operation.
  • Be willing to author process flow diagrams, piping and instrumentation diagrams, and equipment specifications regardless of experience level.
  • Be intentional about project stage-gates and comfortable ending a project and moving on to the next.
  • Be willing to work in an early-stage startup environment with high autonomy and expectations.
  • Be willing to relocate to Chattanooga, Tennessee.
  • Be available to travel to customer sites across the United States, Canada, Brazil, South Africa, and Australia for site visits, on-site testing, detailed engineering, and start-up.
Responsibilities
  • Own the full technical scope of an assigned project and drive it through a stage-gated process, ending it early when appropriate.
  • Lead end-to-end flowsheet development, including comminution and physical concentration, leaching, solid–liquid separation, ion exchange, solvent extraction, precipitation, crystallization, electrowinning, product polishing, residue disposition, reagent regeneration, water balance, and effluent management.
  • Own flowsheet techno-economics to assess project viability and inform company Go/No-Go decisions.
  • Determine where scaled testing is needed to de-risk key unit operations, define critical engineering parameters, and produce product samples for offtake partners.
  • Lead pilot testing as needed to gather data and produce required samples.
  • Lead basic and detailed engineering, including process design, major equipment design, brownfield integration design, FEED, and the complete engineering package; manage EPCM support.
  • Identify, vet, and select process technology vendors from pilot through commercialization.
  • Lead the facility construction scope and manage EPCM support.
  • Ensure successful facility start-up and drive the facility to nameplate capacity while producing on-spec product.

About the company

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.

Simplify's Take

What believers are saying

  • DOE funding in April 2026 validates Kunin's gallium recovery thesis for defense supply chains.
  • Kunin says it raised $1.75 million and is piloting with partners.
  • Export controls on Chinese rare-earth technology keep domestic processing premium and politically supported.

What critics are saying

  • Kunin remains pre-scale; piloting must prove purity, cost, and throughput before 2027.
  • One failed DOE pilot would crush credibility with mines, smelters, and later customers.
  • If gallium economics disappoint, Kunin becomes a science project with no durable buyer.

What makes Kunin Technologies unique

  • Kunin is one of five DOE TRACE-Ga awardees, targeting 12 tons yearly gallium.
  • It claims vertically integrated resin, process, and metal-production capabilities, rare outside China.
  • Its ion-exchange platform targets byproduct metals from mine waste, smelters, and refineries.
