About the Position
As a Senior Principal Data Engineer , you will serve as the primary architect and strategic lead for our MLOps and forecasting platform. You will bridge the gap between advanced data science and production-grade engineering, ensuring that complex models for campaign projections, lift analysis, and budget forecasting are scalable, high-performance production services. You will lead the design of our data infrastructure, overseeing the implementation of automated pipelines using the Databricks Data Intelligence Platform (including Databricks SQL, Unity Catalog, and MLflow) to enable precise, real-time data consumption and model deployment.
You Will
Design and architect a unified MLOps and forecasting platform on Databricks, leveraging MLflow for model orchestration and Databricks SQL for high-scale data processing.
Build and maintain automated pipelines to handle critical business use cases, specifically:
Developing models that simulate past campaign performance using historical transaction data to forecast future outcomes.
Real-time monitoring and prediction of budget utilization to prevent over/under delivery.
Implementing robust Incrementality Testing framework to quantify the causal impact of advertising exposure.
Establish CI/CD and deployment standards to ensure models are scalable, frequently refreshed, and easily debugged.
