What you'll do
- Predictive & ML Modeling: Build, evaluate, and fine-tune supervised/unsupervised machine learning models (e.g., churn prediction, lifetime value estimation, recommendation engines, forecasting).
- Advanced Analytics & Experimentation: Design and execute A/B testing, statistical hypothesis testing, and causal inference models to evaluate product features and strategic business initiatives.
- Data Engineering & Pipeline Development: Construct, maintain, and optimize ETL/ELT pipelines using SQL and Python to clean, transform, and aggregate raw data into feature-ready datasets.
- Analytics Engineering & Business Intelligence: Model data for downstream analytics using frameworks like dbt, building high-performing data schemas (star/snowflake) and self-service BI dashboards (e.g., Tableau, Looker, Power BI).
- Model Deployment & Monitoring: Wrap predictive models into lightweight APIs (e.g., FastAPI) for batch or real-time inferences, setting up automated alerts for data drift, performance degradation, and pipeline failures.
