  • Analyze paid media performance and customer journeys to identify trends, opportunities, and inefficiencies

  • Collaborate with data engineers to refine data models in BigQuery
  • Work with raw and transformed data sources to ensure dashboard integrity and clarity
  • Contribute to building reusable metric definitions and calculated fields
  • Identify gaps in data collection and propose tracking enhancements
  • 3+ years of experience working in BigQuery (data modeling, transformation, SQL optimisation) in a performance marketing capacity
  • Strong proficiency in SQL and experience with Looker Studio (LookML development ideal) or other viz platforms (Metabase etc…)
  • Strong experience with BigQuery
  • Strong understanding of digital media metrics (e.g. CTR, ROAS, CPA, CPV, engagement rate)
  • Ability to translate data into actionable stories and stakeholder-friendly visuals
  • Strong understanding analysing performance media data pulled from Google Ads, Google Analytics 4 (GA4), DV360, or paid social analytics
  • Experience with Adverity, Segment, or similar data connectors
  • Understanding of data modeling best practices (e.g. dbt, Dataform)
