Job Level

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.
  • Support AI and agent-driven use cases by ensuring data is structured, accessible, and reliable.

Requirements

  • 7–10 years of experience in data engineering, analytics engineering, or data architecture in production environments
  • Deep, hands-on SQL skills and are comfortable working directly in complex warehouse environments
  • Experience working across multiple modern data warehouse platforms (e.g., BigQuery , Snowflake, Redshift, Databricks) and understand their tradeoffs
  • Strong experience modeling data using Kimball-style dimensional modeling (fact/dimension design, star schemas)
  • Built or maintained semantic layers or metrics layers that support BI and downstream applications at scale
  • Strong programming skills (Python preferred) and can build or modify APIs, services, or connectors when needed
  • Comfortable reviewing, challenging, and improving engineering implementations
  • Understand how data moves across systems end-to-end, from ingestion through transformation to consumption
  • Comfortable operating in ambiguous environments and taking ownership of the details that make systems actually usable
  • Exposure to AI/ML or LLM-based workflows and understand how data platforms need to evolve to support them.
