Senior Scientist, Sterile Product Development (On-site)

Job Description

S terile Product Development (SPD) group is responsible for developing non-oral dosage forms (injections, implants, inhaled, ocular) for biologics, mixed modalities, vaccines and small molecules from preclinical toxicology studies to commercialization. Our development teams ensure robust composition, primary packaging/ device, and process selection through deep fundamental understanding and characterization such that the process is scalable without compromising stability, safety, efficacy, and delivery. During development, we leverage smart experimental design, cutting edge analytical tools, and predictive approaches to inform molecule, formulation and process selection. In summary, our team enables the translation of preclinical candidates into non-oral drug products.
