Do you want to join one of the fastest-growing molecular diagnostics startups and be a pioneer for an industry-leader who is impacting the lives of millions?

Come help lead our world-class Client Services team and bring your career to the next level working alongside some of the most inspiring leaders in the industry.

BillionToOne, ranked at the top 5% of Y Combinator companies with $250M+ in funding from prominent VC firms, has developed a DNA molecular counter that increases cfDNA diagnostic resolution by over 1,000 fold. BillionToOne's first product, UNITY™ is the first and only non-invasive prenatal test that can directly screen an unborn baby's risk for common and severe recessive gene disorders and chromosomal abnormalities, as well as fetal sex and fetal antigens, from a single tube of blood from the pregnant mother without paternal testing.

In 2023, BillionToOne launched two liquid biopsy products that will markedly improve oncology treatment and care. With Northstar Select™, clinicians will be able to select cancer therapies that will be most effective to each patient based on their individual genetic makeup. Northstar Response™ will enable clinicians to monitor a patient’s early response to these cancer therapies, by measuring minute changes in their ctDNA, which can reduce ineffective treatments and unwanted toxicity, lower costs, and substantially improve clinical outcomes.
