Senior Research Associate I or II, BioAnalytical Science

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.


Do you want to work as part of a team that executes the bioanalytical strategy to understand safety, efficacy, and mechanism of gene therapies and biotherapeutics that change patients’ lives?  Do you want to develop and apply your knowledge of biology, molecular biology, immunology and biochemistry in delivering novel bioanalytical assays in support of non-clinical studies and clinical trials?
