Contract research organization for preclinical drug development and safety testing
Charles River operates a sprawling contract research business supporting early-stage drug discovery and safety validation, with 10,000+ employees across research, operations, and manufacturing. The tech stack reveals a major cloud migration underway—heavy Azure + AWS adoption, active Databricks implementations, and systematic replacement of legacy Windows-era frameworks (WinForms, Java Swing, WCF)—paired with hiring acceleration across research (282 roles) and data engineering (26 roles). This pattern suggests simultaneous execution on two fronts: modernizing internal systems while scaling the data infrastructure needed to accelerate throughput in viral clearance, toxicology, and GLP-compliant studies.
Notable leadership hires: Head of CSD, Team Lead, Business Development Director, Business Optimisation Lead, Study Director
