Senior Data Scientist, Prenatal
About The Position
Join BillionToOne, a category-defining, publicly traded company on Nasdaq, focused on transforming healthcare through molecular diagnostics. We are seeking a Senior Data Scientist to join our Prenatal data team. In this high-impact, high-autonomy role, you will own the entire analytics value chain, from data engineering to analysis and insight delivery. You will work directly with stakeholders across various departments, including commercial, lab operations, clinical, quality, bioinformatics, and executive leadership. AI is integral to our workflow, and you will use it daily to accelerate your analyses, build HIPAA-compliant AI-powered workflows, and help colleagues adopt AI for improved productivity. Our mission is to make life-changing diagnostics accessible to all, and we build products that are 10x better than existing solutions.
Requirements
- 3+ years of experience in a data science, analytics engineering, or related data role. More experience is welcome.
- Strong proficiency in SQL and Python (or R) for data manipulation and analysis.
- Comfort working with messy, disparate data sources and the judgment to know when to clean, when to re-model, and when to push upstream.
- Experience working with clinical, healthcare, or other regulated data.
- Hands-on experience using AI tools to enhance your work, and an interest in helping others do the same.
- Excellent communication skills and the ability to partner directly with non-technical stakeholders to scope problems and deliver useful answers.
- A strong sense of ownership: you are comfortable working directly with stakeholders and treat data quality and stakeholder outcomes as part of your job.
Nice To Haves
- Familiarity with dbt, Airflow, Tableau, Stitch, Hightouch, Cursor, Claude, ChatGPT, AWS (S3, Batch, RDS, MWAA), and Clarity.
- Familiarity with bioinformatics, molecular diagnostics, or the broader healthcare landscape — including the lab sales cycle, prior authorization, and reimbursement.
- Background in the biosciences.
Responsibilities
- Own the full analytics stack for Prenatal: ingest data from disparate sources into our central data warehouse, build clean and well-tested data models, and deliver analyses, dashboards, and tooling that stakeholders can use directly.
- Partner with stakeholders across the business to answer high-stakes questions with data — for example, helping the lab improve turnaround time, helping sales identify at-risk accounts and new business opportunities, supporting clinical affairs with data on samples and outcomes, supporting business metrics around new product launches, and informing executive decisions on growth and strategy.
- Build and maintain the central analytical data warehouse that aggregates data from across the organization, while partnering with teams who own their own operational systems (e.g., Clarity, bioinformatics pipelines).
- Use AI tools to accelerate your own work, build HIPAA-compliant AI-powered analysis workflows, and help colleagues across the company adopt AI to improve their productivity.
- Develop and maintain Tableau dashboards and self-serve analytics that turn data into action for clinical, commercial, and operational teams.
Benefits
- Working 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
