The Assay Strategy and Development(AS&D) group within the BioAnalytical Sciences (BAS) department at BioMarin develops and characterizes novel assays to measure pharmacokinetics, immunogenicity and biomarkers of new therapeutics. We are searching for an experienced bench scientist to oversee the transfer and validation of bioanalytical assays at Contract Research Organizations (CROs), as well as use of these assays to test samples from non-clinical and clinical studies. The individual will also be called upon todevelop and characterizeinnovative assays to assess the safety and efficacy of new therapeutics in development. This position offers a unique career opportunity to work on the entire spectrum of a product lifecycle, from early proof of concept non-clinical work through all stages of clinical development, including post-approval. The successful candidate will interact with Research, Translational, and Clinical Scientists to advance our most promising pipeline therapeutics focused on rare diseases.
