Sr. Principal / Staff Scientist - Anatomic Pathologist, Pharmaceutical Sciences

Location San Rafael, California
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 Pharmacological Sciences Department at BioMarin is seeking a Sr. Principal / Staff Pathologist (Sr. / Executive Director level) with extensive drug development experience to provide veterinary pathology expertise for the development of BioMarin’s gene therapy, small molecule and biologic drug candidates.  This individual will provide scientific leadership and play a pivotal role in providing pathology expertise in support of all phases of the drug development process from late-stage research through market application.

The successful candidate will have a strong anatomic pathology background with demonstrated experience in drug development and toxicologic pathology.  The candidate will interact with pharmacologists, toxicologists and other scientists across Research and Early Development in order to provide a balanced assessment of the risk/benefit profile associated with a drug candidate’s advancement. The individual will be responsible, in collaboration with other scientists, for the design, implementation and interpretation of GLP and non-GLP studies to ensure comprehensive pharmacological and safety profiling of drug candidates.  The successful candidate will have experience providing context of findings to senior management and offering insights for clinical endpoints and strategies.
