• Design and conduct rigorous statistical analyses and build robust predictive models to answer complex business questions, selecting appropriate methods (e.g., regression, time series, survival/attrition, hypothesis testing, graph and network analysis) for the problem at hand.
• Design and implement production-ready pipelines that can handle large-scale datasets, leveraging distributed processing systems (e.g., Snowflake, Databricks, Google Cloud Platform) and building reusable, modular components.
• Write readable, well-structured, modular code using standard libraries, and ensure your work is tested, documented, and maintainable by others.
• Participate in code and design reviews, giving and receiving constructive feedback to raise the quality bar across the team.
• Contribute to shared practices, tooling, and documentation that improve how the data science function operates.
• Share knowledge with teammates and provide informal guidance to more junior colleagues on modeling, code, and analysis approaches.
