Senior Scientist - Ion Exchange
About The Position
Kunin Technologies is revolutionizing the critical mineral supply chain by implementing advanced separation technologies to capture value from overlooked resources. Metals are everywhere—in solar panels, smartphones, electric vehicles—but as ore grades plummet globally, traditional extraction methods are failing. China dominates critical minerals markets by developing superior separation technologies that extract value from materials American mines discard as waste. Utilizing Kunin Technologies’ breakthrough mass manufacturable nano-separation systems, significantly more value can be produced from each resource, reducing waste, and unlocking domestic critical mineral production. Kunin is commercializing a novel ion-exchange media form factor and system design that decouples kinetics from pressure-drop, unlocking orders of magnitude improvements in throughput compared to resin-in-columns systems. You will lead ion-exchange technology development, unlocking a new pandora’s box of processing innovations from critical minerals to beyond.
Requirements
- PhD in Chemical Engineering, Polymer Science, or Polymer Engineering.
- Ion-exchange scientist with at least 5 years in resin chemistry, column science, and hydrometallurgical separations.
- Practitioner of polymerization, functionalization, and conditioning with measured control of crosslinking, porosity, swelling, and mechanical strength.
- Experimentalist fluent in analytical and physical testing — SEM, BET, FTIR, ICP-OES/MS, TGA/DSC.
- Modeler skilled in equilibrium, speciation, and kinetic frameworks using MetSim, HSC Chemistry, OLI Studio, PHREEQC.
Responsibilities
- Ion-exchange resin synthesis, functionalization, and conditioning tied to kinetic and selectivity objectives.
- Modelling of resin backbone composition-dependent dimensional stability.
- Lead novel resin form factor qualification and stress testing protocols.
- Column testing programs optimizing mass transfer, breakthrough, regeneration, and leakage control.
- Develop novel selective elution strategies from first principles and translating to multi-species partitioning in multi-column series or parallel pilot systems.
- Lead joint development programs with novel ligand development partners.
- Execute the manufacturing scale-up of novel ion-exchange resin media.
