This is a high-impact, high-autonomy role with a suite of benefits, including paid medical and family leaves, a retirement savings program with company contribution, and a generous equity package.

• Ingest data from disparate sources into the 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, helping the lab improve turnaround time, helping sales identify at-risk accounts and new business opportunities.
• 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.
• Master's or PhD with 2 year of work experience, OR Bachelor's degree with 4 years of work experience, in data science, analytics engineering, or a related data role. More experience is welcome
• Excellent communication skills and the ability to partner directly with non-technical stakeholders to scope problems and deliver useful answers
• Strong proficiency in SQL and Python (or R) for data manipulation and analysis
• Hands-on experience using AI tools to enhance your work, and an interest in helping others do the same
• Comfort working with messy, disparate data sources and the judgment to know when to clean, when to re-model, and when to push upstream
• A strong sense of ownership: you are comfortable working directly with stakeholders and treat data quality and stakeholder outcomes as part of your job
• Experience working with clinical, healthcare, or other regulated data
• Familiarity with any of the tools we use is a plus: 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 — is also a plus, as is a background in the biosciences
