• Demonstrated experience with Foundry pipeline development (PySpark/Pipeline Builder), Code Repositories, ontology/object modeling, and Foundry Workshop application building
• Working experience with Databricks, including notebooks, Delta Lake, and Spark-based data processing, as a secondary platform to Foundry
• Proficiency in Python and SQL for data manipulation and pipeline development (pandas, PySpark, numpy, or similar)
• Familiarity with data visualization approaches (D3.js, Plotly, Recharts, or Foundry-native Workshop widgets) for surfacing pipeline outputs
• Demonstrated experience in planning, analyzing, designing, implementing, testing, and maintaining data pipelines and applications for an enterprise-level system
• Familiarity with Git, Agile methodologies, CI/CD, and automated deployments
• Demonstrated experience in leadership roles, technical mentorship, or client relationship management
