At BillionToOne, we've built a category-defining, publicly traded company on Nasdaq where transparency fuels trust, collaboration drives breakthroughs, and every contribution moves the needle on our mission to make life-changing diagnostics accessible to all. We don't just aim for incremental improvements; we build products that are 10x better than anything that exists today.\nOur scientists, engineers, sales executives, and visionaries are united by an unwavering commitment to changing the standard of care in prenatal and cancer diagnostics. This is where cutting-edge science meets human compassion, and every innovation you contribute helps remove the fear of the unknown from some of life's most critical medical moments.\nIf you're driven by purpose, energized by innovation, and ready to help shape the future of precision medicine at scale, this is where you belong.\nThe Research Associate position at BillionToOne is exceptionally rare at the undergraduate or early-career level. At BillionToOne, you will do much more than simply run routine protocols. Your work will help shape the development of high-impact molecular diagnostic products that are actively changing patient outcomes in both oncology and prenatal medicine. This is your chance to contribute to building novel molecular tests that help patients from day one.\nYou will work alongside and be mentored by scientists with interdisciplinary expertise across molecular biology, genomics, bioinformatics, and quantitative modeling. You will have the chance to use cutting-edge molecular techniques, next-generation sequencing, and robotic tools to move assays from research prototypes to commercially available products run at large scale on real patient samples in our clinical lab. Whether your ambition is to grow here at BillionToOne or ultimately pursue graduate studies, this position would be a solid foundation for your scientific career.\nThe Research Associate is an on-site position in our Menlo Park, CA office.\nWho We’re Looking For:\nStrong statistical and quantitative skills: You think rigorously about data. You understand the difference between signal and noise, appreciate the importance of statistical power, and bring quantitative reasoning to every problem.\nMeticulous attention to experimental detail: You understand that the quality of an experiment determines what we can learn from it. You keep rigorous records, design careful controls, and take pride in work that others can rely on and build upon.\nAmbition to make a difference now: You aren’t here to punch the clock. You want to understand why things work, push the boundaries of what’s known, and do what it takes to see your contributions show up in products that help real patients.\nExcellent communication in a fast-paced, collaborative environment: We move quickly and we move together. You share findings clearly and proactively, ask questions early rather than late, and work seamlessly across scientists, engineers, and cross-functional teams to keep projects moving.\nResponsibilities:\nDesign, execute, and troubleshoot experiments and assays under the guidance of Senior Scientists\nLearn analytical and computational methodologies to analyze results under the guidance of Senior Scientists\nPresent scientific findings both verbally at group meetings and via internal written reports\nDocument experimental details and results\nCollaborate with other teams to implement lab and bioinformatic workflows\nContribute positively to organizing and maintaining the R&D lab\nQualifications:\nBS or MS in Bioengineering, Molecular and Cell Biology, Microbiology, Biophysics, Biochemistry, or related field\n1-2 years of research experience (either during BS/MS or afterwards)\nPrevious experience with standard molecular biology techniques (in particular, extensive experience with PCR, electrophoresis, DNA purifications)\nAn ability to quickly learn mathematical, analytical, and experimental concepts\nHigh mathematical and statistical aptitude (e.g., you find the GRE math section to be extremely easy)\nGreat attention to detail\nNice-To-Haves:\nStart-up experience\nKnowledge of medical genetics\nExperience in a cell-free DNA setting\nExperience with next-generation sequencing library preparation\nExperience with computational analysis in R, Python, or other programming language\nBenefits And Perks:\nWorking alongside brilliant, kind, passionate and dedicated colleagues, in an empowering environment, toward a global vision, striving for a future in which transformative molecular diagnostics can help millions of patients\nOpen, transparent culture that includes weekly Town Hall meetings\nThe ability to indirectly or directly change the lives of hundreds of thousands patients\nMultiple medical benefit options; employee premiums paid 100% of select plans, dependents covered up to 80%\nExtremely generous Family Bonding Leave for eligible employees (16 weeks, paid at 100%)\nSupplemental fertility benefits coverage \nRetirement savings program including a 4% Company match\nIncrease paid time off with increased tenure\nLatest and greatest hardware (laptop, lab equipment, facilities)\nDaily on-site lunches provided from top eateries\nA variety of perks on campus (state of the art gym, restaurant)\nFree on-site EV charging (compatible with all EVs, including Tesla)\nAt BillionToOne, we are proud to offer a combination of a (1) base pay range (actual amount offered is based on experience and salary/equity options split that the candidate chooses), (2) generous equity options offering, (3) corporate bonus program, on top of (4) industry leading company benefits (free healthcare options, 401k match, very generous fully paid parental leave, etc.).\nFor this position, we offer a total compensation package of up to $104,322 per year, including a base pay range of $75,029 - $85,748 per year.\nBillionToOne is an equal opportunity employer.
