  • Expertise with Python and/or R as well as SQL, with experience using Snowflake, Databricks, or other big data technologies a plus

What will be your key responsibilities?

  • Develop campaign visualization templates to be reused on the CDP, with an eye toward purposeful design and aesthetics that aid in data comprehension, especially as it relates to quantifying the impact and value of digital channels such as paid and organic search, email, media, social, and influencers
  • Design front-end visualizations for internally developed consumer data products, partnering with the data engineering team for performance and optimization
  • Collaborate with stakeholders across multiple functions to gather design requirements, working in an agile framework for frequent, iterative updates
