Sr. Scientist I/II - Nonclinical Pharmacology / Toxicology, Pharmacological Sciences

BioMarin is the world leader in delivering therapeutics that provide meaningful advances to patients who live with serious and life-threatening rare genetic diseases. We target diseases that lack effective therapies and affect relatively small numbers of patients, many of whom are children. These conditions are often inherited, difficult to diagnose, progressively debilitating and have few, if any, treatment options. BioMarin will continue to focus on advancing therapies that are the first or best of their kind. 

BioMarin’s Research & Development group is responsible for everything from research and discovery to post-market clinical development. Research & Development involves all bench and clinical research and the associated groups that support those endeavors. Our teams work on developing first-in-class and best-in-class therapeutics that provide meaningful advances to patients who live with rare diseases. Come join our team and make a meaningful impact on patients’ lives.

The Pharmacology and Toxicology Department at BioMarin is seeking an experienced Senior Scientist I/II to provide nonclinical pharmacology and/or toxicology expertise for the development of BioMarin’s novel 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 research through market application and commercialization.

The 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 pharmacological / toxicological profile of drug candidates.  This individual will work collaboratively with internal and external cross-functional sub-teams, collaborators and consultants to contribute to integrated development pathways throughout the drug development cycle. 

The successful candidate will have a pharmacology or toxicology background as well as a strong understanding of pharmacological mechanisms of disease and will provide broad-based support to align nonclinical efforts with the company’s opportunistic philosophy of drug development.  The candidate will interact with collaborators and 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 sub-teams, external collaborators, and the scientific community.  This individual will actively participate in representing Pharmacological Sciences on cross-functional project teams and/or lead project sub-teams.
