Job Description:

E Ink California is seeking an experienced Polymer Scientist to join the Materials R&D group. As part of an innovative research team, this candidate will bring novel polymer formulation and material science expertise to contribute to new coating materials research and product development in the field of electrophoretic displays (EPD).


  • Design, develop, and prepare novel coating formulations at lab scales. Source polymers and other materials with desired properties, formulate, and optimize compounding process to provide desired functions and meet product specifications.
  • Investigate and explore new ideas, demonstrate proof-of-concept, create new intellectual property.
  • Execute fundamental mechanism studies on structure-property relationships. Correlate polymer and formulation properties to coating qualities and final EPD performance, identify parameters that are critical to function, and improve EPD performance based on polymer formulation design.
  • Establish quality control test methods for raw materials, formulations, and final coatings. Analyses can include, and are not limited to, tests on physical, mechanical, chemical, adhesive, and electrical properties. Develop in-process and final product related specifications on the polymer formulation and coating.
  • Work with pilot engineers to co-optimize the formulation and process, introduce new coating formulations to new product platforms.
  • Transfer coating formulation and process to manufacturing facilities through effective communication, documentation, and training.
  • Provide technical lead in manufacturing troubleshooting, analyzing product failure to identify root causes, and developing solutions.
  • Effectively communicate with all levels of the organization and promote and contribute to a cohesive team working culture. Participate in cross-functional teams in technology and product development.


  • PhD in Polymer Science, Chemical Engineering, Materials Science, or related field, with at least five years industry experience.
  • Demonstrable experience in new product development and technology transfer, capable of executing and completing complex research projects.
  • Hands-on experience in polymer formulations (UV curable materials, water-borne coatings, adhesive coatings, etc.), with in-depth understanding of structure-property relationships of polymers.
  • Strong analytical skills and familiarity with statistical analysis, DOE, and root cause analysis. Demonstrated skills in solving complex product/process issues.
  • Experience in troubleshooting, using data driven approaches to problem solving, and an ability to work under pressure.
  • Solid background and knowledge on roll-to-roll coating formulations, interfacial chemistry, and surface chemistry.
  • Enthusiastic and motivated collaborator. Goal-oriented and able to handle multiple tasks. Excellent communicator. Creative problem solver, innovative, and committed to continuous learning.
