Senior Scientist II, Toxicologist

BioMarin Pharmaceutical Inc.•San Rafael, CA

About The Position

BioMarin is a leading rare disease biotechnology company focused on genetically defined conditions. The Pharmacology and Toxicology Department at BioMarin is seeking a Senior Scientist 2 to provide nonclinical pharmacology and toxicology expertise for the development of BioMarin’s small molecule and biologic drug candidates. This individual will provide scientific leadership and play a pivotal role providing nonclinical expertise in support of all phases of the drug development process from late-stage research through market application and commercialization. A successful candidate will contribute to the strategic development of BioMarin’s therapeutics by creating a best-evidence synthesis of existing knowledge and by designing, implementing, interpreting, investigating and reporting data that elucidates the pharmacologic/toxicologic profile of drug candidates. This individual will work collaboratively with internal and external cross-functional subteams, collaborators and consultants to contribute to integrated development pathways including regulatory submissions throughout the drug development cycle. Comprehensive analysis and interpretations of these studies are reported and defended to regulatory agencies in meetings and documents such as briefing documents, IND/CTA, annual updates, investigator brochures, special protocol assessments and market applications. The successful candidate will have a pharmacology/toxicology background as well as a strong understanding of Good Laboratory Practices (GLPs) and will provide broad-based support to align nonclinical efforts with the company’s opportunistic philosophy of drug development. The candidate will interact with scientists across the company in order to provide a balanced assessment as to the risk/benefit profile associated with a drug candidate’s advancement. The individual will be responsible for the planning, implementation and organization of nonclinical studies along with the use of drug exposure to bridge across species, presentation of data (written and verbal) to cross-functional core teams and subteams, external collaborators, and the scientific community. This individual will actively participate in representing Pharmacological Sciences on cross-functional project teams and/or lead project subteams.
