A research and development chemist is a scientist who focus on developing new products or improving existing products. This involves conducting experiments to test the feasibility of new product ideas, developing prototypes, and optimizing production processes. R&D chemists typically work in teams with engineers and other scientists, and may also interact with customers or marketing staff to understand their needs and develop products that meet their demands. As such, they need to have strong communication and problem-solving skills, as well as a good understanding of chemistry and engineering principles. With the right skills and experience, research and development chemists can play a key role in the success of a company by bringing new products to market.
