Description :
Do you want to help bring prenatal diagnostics into clinical practice and improve lives of millions of expecting parents?

BillionToOne (Y Combinator S17) has developed a molecular counter that improves cell-free DNA diagnostics resolution by 1000x. This allows us to revolutionize multiple fields, from prenatal testing to oncology. With our first flagship UNITY and UNITY Complete prenatal tests, we have grown our sample volume by more than 300% even during the pandemic. We are currently automating more of our processes and building a 10x larger clinical laboratory that will be able to process 1500+ samples per day.

We are looking for a driven Clinical Laboratory Scientist (with California Clinical Laboratory Scientist License) to perform UNITY, the only non-invasive prenatal test (NIPT) that can detect inherited disorders such as sickle cell disease, spinal muscular atrophy, and cystic fibrosis in the baby directly from maternal blood. These disorders are extremely severe, but early detection and intervention can significantly improve outcomes. You will join our growing superstar CLIA team responsible for end-to-end processing of pregnancy blood samples in a high complexity, high-growth CLIA setting.

More About Us:

BillionToOne has developed noninvasive prenatal tests for the most common genetic disorders in the world. More than 100 million people are carriers for these disorders. The prenatal detection of these disorders currently requires invasive methods with high miscarriage risk, but we have developed tests that solve this important problem.

BillionToOne has raised a large Series A and Series A+ funding (~$35M) from global institutional investors, including from Hummingbird Ventures, Neotribe Ventures and Y Combinator.
