Job Description

General Summary:

Formulation Development at Vertex seeks a dedicated scientist to join a team whose goal is to discover, develop, and commercialize therapies for patients with serious diseases. As a member of Formulation Development team, this role will support to develop preformulations of small molecule chemical entities to support PK, pharmacology, and toxicology studies at our San Diego site. The preformulation function is part of the global Formulation Development organization, a critical R&D function enabling the manufacturing of dosage forms along the complete development timeline from molecule selection to commercial. The primary responsibility for this position is to enable candidate selection within Vertex's promising pipeline of small molecules. The candidate will be responsible for exploring the formulation space for supporting a variety of preclinical studies to advance molecules to the clinic. The candidate is expected to help lay the foundations for future clinical development by successfully executing developability assessments and robust experimental physicochemical characterization of molecules and prediction of in-vivo bioperformance using modeling tools. The candidate will collaborate extensively with colleagues in discovery biology, chemistry, DMPK, and CMC functions. The ideal candidate has mastered the fundamentals of chemistry and physics and has direct experience in a research laboratory The candidate must comfortably take the initiative, be curious, and show resilience in solving complex problems

Key Duties and Responsibilities:

  • Development of various formulations including oral, and intravenous of small molecule drug candidates to support early PK and pharmacology studies.
  • Design, plan, execute, and interpret laboratory experiments to meet established project timelines for molecule selection and advancement
