Senior Research Associate 1, Assay Strategy and Development, Translational Sciences

Location San Rafael, California Workstyle Onsite Only

Who We Are

From research and discovery to post-market clinical development, our WWRD engine 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 genetic diseases.


The Assay Strategy and Development group within Translational Sciences develops methods for the detection of drugs, antibodies to therapeutics, and biomarkers in biological matrices to support projects through multiple stages of development. We are searching for a talented and highly motivated Senior Research Associate (SRA) to join a bioanalytical team that will be responsible for the generation of data to enable the successful development of pre-clinical and clinical programs. The candidate will be responsible for the development of assays for diverse modalities, which may include gene therapies, monoclonal antibodies, oligonucleotides, biologics, and small molecules. Candidates should be familiar with guidance documents for regulated sample testing and should have experience developing bioanalytical methods.

The successful candidate will participate in programs that range from exploratory in vitro and animal studies to non-clinical efficacy, safety studies, and clinical trials. You will be responsible for developing new methods, evaluating novel technologies, and conducting translational research internally at the BioMarin Research Center and externally in partnership with contract research organizations. This position offers a unique opportunity to interact with scientific and business colleagues across many functional areas, including Research, Translational Sciences, Regulatory Affairs, and Clinical Sciences.

This SRA position will report to a Scientist II in the Assay Strategy and Development group and will have the opportunity to advance our most promising pipeline programs to treat rare genetic diseases.
