About this role

Vertex is seeking an on-site Principal Research Associate, Analytical Chemistry to support medicinal chemistry programs through small molecule purification, analytical characterization, property assays and workflow optimization. This role will focus on HPLC and SFC purification, with a strong emphasis on SFC expertise, to help deliver high-quality compounds and data that enable rapid discovery efforts.

Day-to-day, you will purify small molecules using HPLC and SFC, develop and optimize SFC purification methods including chiral and achiral separations, and perform analytical testing to confirm purity, identity, and quality of compounds.
