Key Responsibilities

Key Responsibilities

Forecasting & Modeling

• Design and deploy production-grade forecasting solutions using statistical models (ARIMA, ETS, BSTS) and ML approaches (XGBoost, LightGBM, neural networks)
• Engineer sophisticated features: lag features, rolling statistics, external signals, calendar effects, and domain-specific transformations
• Implement forecast reconciliation and hierarchical aggregation for complex business structures
• Establish rigorous evaluation frameworks: backtesting, time series cross-validation, accuracy metrics, prediction intervals, and drift monitoring

Software Engineering & Infrastructure

• Write production-grade Python and R code with modular architecture, comprehensive testing, error handling, and documentation
• Build and maintain sophisticated R Shiny applications with integrated JavaScript components
• Orchestrate ML pipelines using Kubeflow for automated training, validation, deployment, experiment tracking, and model versioning
• Manage infrastructure as code: Databricks workspaces, Azure resources, CI/CD pipelines (GitHub Actions, Azure DevOps), containerization, and secrets management

Analysis, Debugging & Monitoring

• Troubleshoot complex issues across the full stack: data pipeline failures, model degradation, API errors, and integration problems
• Implement continuous monitoring: automated data quality checks, feature drift detection, performance tracking, and alerting systems
• Conduct root cause analysis of forecast errors, identify data anomalies, validate business logic, and communicate findings clearly
