The ideal candidate is an experienced data engineer and can serve as a thought leader on the team for organizing structured and unstructured data, managing data pipelines, building data models, and scaling our data warehouses. Our data provides the best understanding of consumer purchase behavior, that needs daily updates and availability across many countries.

Here’s a comprehensive list of challenges that may present themselves as part of the role:

  • What options exist to scale our data warehouse to support growing concurrency and report complexity?
  • How would we process and organize a new stream of semi-structured data with 10m events/day?
  • What solutions should be solved with a MPP data warehouse solutions versus a map-reduce system?
  • Determine SLA strategy with Product & Business partners for new data sets
  • When should we employ an ETL strategy versus and ELT strategy?
