Job description

Join Sepax Technologies and help develop the next generation of chromatography materials.

We are seeking an R&D Scientist with expertise in polymer chemistry, materials chemistry, and/or surface modification to contribute to the development of advanced separation materials and HPLC products.

This is a hands-on research position for a scientist who enjoys designing experiments, synthesizing and modifying materials, solving complex chemistry problems, and translating laboratory research into real-world separation technologies.

The successful candidate will work on projects involving polymer and/or silica-based materials, surface functionalization, particle chemistry, chromatography, and separation science at our headquarters in Newark, Delaware.


Required Qualifications

  • Ph.D. in Chemistry, Polymer Chemistry, Materials Science, Chemical Engineering, or a closely related discipline.
  • Strong hands-on research experience in polymer synthesis, materials synthesis, surface chemistry, surface modification, functionalization, or related chemistry.
  • Demonstrated ability to independently design experiments, troubleshoot synthesis challenges, interpret results, and optimize experimental conditions.
  • Experience using analytical and characterization techniques to evaluate synthesized or modified materials.
  • Strong scientific documentation, data analysis, and technical communication skills.
  • Ability to work independently while collaborating effectively within a multidisciplinary R&D environment.

Highly Preferred Experience

  • Silica particle synthesis and/or silica surface modification.
  • Polymer functionalization, grafting, coating, or surface immobilization.
  • Development of porous materials or functional particles.
  • HPLC stationary-phase or chromatography-media development.
  • HPLC method development and separation science.
  • Understanding of structure-property relationships as they relate to chromatographic performance.
  • Experience taking a material or chemistry concept from initial synthesis through optimization and performance evaluation.

What You'll Work On

  • Design, synthesize, modify, and characterize advanced materials for chromatographic separations.
  • Develop and optimize surface-modification and functionalization chemistries.
  • Investigate relationships between material structure, surface chemistry, and chromatographic performance.
  • Design experiments to troubleshoot synthesis, reproducibility, and product-performance challenges.
  • Evaluate new chemistries and materials for potential use in HPLC stationary phases and separation products.
  • Collaborate with R&D, Technology, and Production teams to transition successful research concepts toward scalable products.
  • Document experimental methods, results, conclusions, and recommendations.
  • Contribute scientific ideas to new product development and continuous improvement of existing technologies.
  • File patent applications.
