The R&D Senior Chemist is responsible for conducting specialized analyses, testing, and the formulation of new products, with a focus on latex and water-borne resin synthesis. This role involves developing and refining chemical formulations, executing moderate-scale projects or components of larger initiatives, and establishing quality standards. The Senior Chemist independently manages the commercialization of new resin while collaborating closely with manufacturing teams to support scale-up and production. With expertise in polymer synthesis and coating formulations, the chemist provides technical leadership across multiple product lines, applications, and markets. Additionally, this role may include supervising support-level technicians and mentoring entry-level chemists.

Job duties include contact with other employees and access to confidential and proprietary information and/or other items of value, and such access may be supervised or unsupervised. The Company therefore has determined that a review of criminal history is necessary to protect the business and its operations and reputation and is necessary to protect the safety of the Company’s staff, employees, and business relationships.
