Junior Polymer Chemist

Cyclopure is a material science and technology company that is developing a new class of selective adsorbents. The company’s technology allows the conversion of renewable cyclodextrins into porous, highly adsorbent materials that are ideally suited for water treatment.

At its Research & Technology Center located in Skokie, IL, Cyclopure is commercializing two lead adsorbent formulations, DEXSORB® and DEXSORB+, for the remediation of a broad range of micropollutants from water resources. Cyclopure’s patented materials can be produced in varying particle sizes, allowing for flexible use in water treatment applications. More information about the company can be found at

Cyclopure is seeking a highly motivated synthetic and/or polymer chemist to participate in efforts to develop new adsorbent formulations, optimize production processes to support scale-up and commercial production, and test them in various form factors for a wide range of application types.
