Design data models and semantic layers on client platforms like Snowflake and Databricks, interrogating data quality and business logic before modeling.

  • Cloud data platform experience (Snowflake, Databricks, Azure/AWS/GCP)

Desired Qualifications

  • Mathematics, Statistics, or Operations Research major
  • Formal mathematical training and the ability to reason from first principles about optimization, probability, and model assumptions
  • Advanced degree (MS/PhD) in a quantitative field
