About the role
- Design and refine dimensional data models (fact/dimension, star schemas) to support analytics and AI use cases.
- Write, review, and optimize SQL used across the warehouse and semantic layer.
- Build and evolve the semantic or metrics layer to ensure consistent, trusted business definitions.
- Partner directly with data engineers to review implementations, challenge design decisions, and improve data pipelines.
- Debug data issues across the stack, from ingestion through transformation to consumption.
- Modify or extend APIs and services to make data and functionality accessible for downstream systems and AI workflows.
- Build connectors or lightweight services that enable systems to interact programmatically.
- Translate business and product requirements into practical data models and system designs.
- Identify gaps in the current architecture and drive pragmatic improvements without overengineering.
