Scientist, Molecular Biology

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 Biology Research (BR) group at BioMarin is seeking a highly motivated scientist to conduct preclinical translational research evaluating potential therapeutics for severe rare genetic diseases with unmet medical needs. The successful candidate will partner closely with a team of scientists from BR, other functional groups within BioMarin Research, and bioanalytical sciences to advance our most promising molecules for further development. 

He/she is a highly motivated molecular biology scientist who conceives strategies, leads the development, evaluation and implementation of state-of-the-art quantitative molecular methods in support of preclinical proof-of-concept and mechanisms of actions in vivo and in vitro studies of novel therapeutics.  These methods may be used to quantitate biotherapeutic levels, to detect and characterize immune responses evoked by the therapeutic, to measure biomarkers, or for biological mechanistic characterization of drug candidates in complex biological matrices.  This individual is expected to be a mentor for a recognized area of technical expertise within the department.  This individual may also be asked to lead technical teams or initiatives.
