Job Description:
Who We Are At BioMarin , we are driven by a singular mission: to
transform lives through bold science. As a global biotechnology
leader, we specialize in translating genetic discoveries into
groundbreaking therapies that redefine the future of human
health.Since 1997, we’ve leveraged our deep expertise in genetics
and molecular biology to develop innovative treatments for rare and
serious genetic conditions. Our approach is rooted in scientific
rigor, a passion for solving complex problems, and a commitment to
delivering meaningful advances for patients with unmet medical
needs.We bring together top-tier talent—scientists, innovators, and
problem-solvers—and foster a collaborative environment where bold
ideas thrive. This has enabled us to build a diverse pipeline of
commercial, clinical, and preclinical candidates with the potential
to be first-in-class or best-in-class therapies. About Worldwide
Research and Development (WWRD) WWRD spans the full spectrum of
drug development—from early discovery through post-market clinical
research. Our integrated teams work across disciplines to develop
transformative therapies that make a real difference in the lives
of patients with genetic diseases. Position: Senior Scientist,
Biophysical Characterization Location: San Rafael, CA Department:
