• Use Python for data wrangling, automation, statistical analysis, modeling, and repeatable analytical workflows.
• Apply appropriate data science techniques such as segmentation, forecasting, classification, regression, clustering, propensity modeling, or other statistical methods.
• Translate ambiguous client or business asks into structured analytical approaches, assumptions, outputs, and timelines.
• Build clear, client-ready deliverables in PowerPoint, Excel, dashboards, or other reporting formats.
• Perform QA on data, code, methodology, and outputs to ensure accuracy and defensibility.
• Support basic data engineering tasks such as dataset creation, data cleaning, feature generation, pipeline logic, and workflow automation.
• Work with cloud-based data platforms, notebooks, compute servers, and shared analytics environments.
• Mentor analysts and junior data scientists on SQL, Python, analytical methods, documentation, and quality control.
• Partner with cross-functional teams across analytics, product, engineering, consulting, and client-facing functions.

What You'll Bring

• 5+ years of experience in data science, advanced analytics, healthcare analytics, life sciences analytics, analytics consulting, or a related quantitative role.
• Bachelor's degree in Data Science, Statistics, Computer Science, Engineering, Mathematics, Economics, Public Health, or a related quantitative field.
• Strong hands-on SQL experience, including complex joins, CTEs, aggregations, window functions, data validation, and performance-aware querying.
• Strong hands-on Python experience using libraries such as pandas, NumPy, scikit-learn, statsmodels, or similar tools.
• Experience working with large, complex datasets and turning them into actionable insights.
• Practical understanding of data science methods and when to apply them to business problems.
• Basic understanding of data engineering concepts such as ETL/ELT, data pipelines, data models, data quality checks, and reusable workflows.
• Experience working in cloud-based or server-based analytics environments such as Databricks, Snowflake, AWS, Azure, GCP, or similar platforms.
• Strong communication skills with the ability to explain technical work to nontechnical stakeholders.
• Ability to manage multiple priorities, work independently, and maintain strong attention to detail.

Preferred Qualifications

• Experience in healthcare, life sciences, pharma, medtech, payer/provider analytics, commercial analytics, or real-world evidence.
• Experience with healthcare claims, EHR/EMR, provider, patient, HCP/HCO, prescribing, sales, market access, or similar datasets.
