Senior Scientist

Palo Alto, California, United States


Do you want to develop prenatal diagnostics that can affect the lives of millions of expecting parents? BillionToOne (Y Combinator S17) is looking for a quantitative scientist or bioengineer to develop our product pipeline. As part of our technology platform, we have repurposed decades-old Sanger sequencing to generate quantitative molecular data that match next-generation sequencing within less than 1% CV. This has incredible implications for decreasing the cost of molecular genetics tests and making them available and affordable across the world.

You will own R&D for our Sanger-based sequencing platform and translate our proprietary molecular counting technologies to novel clinical diagnostics, with tremendous potential to bring prenatal testing to the world. This is an extremely impactful position, appropriate for an inspired scientist and extraordinary problem solver.

More About Us:

BillionToOne detects genetic disorders in the baby through a simple blood test of the mother. Our first test for beta-thalassemia and sickle cell disease is already in clinical trials. These are the most common genetic disorders in the world, and their prenatal detection currently requires invasive methods with high miscarriage risk. More than 100 million people are carriers for these disorders. By being able to detect both large chromosomal disorders as well as single gene disorders at much lower costs, we aim to make prenatal genetic testing available for all, including in developing countries.

BillionToOne has raised funding from institutional funds and VCs such as Y Combinator, Fifty Years, Uphonest Capital, Civilization Ventures as well as from prominent angel investors who previously invested in SpaceX, Box, and Palantir.


We offer highly competitive salary and benefits combined with a truly generous equity package. You will be working on interesting problems with extremely high-impact.

BillionToOne is an equal opportunity employer. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
