  • Comfort working cross-functionally and independently owning complex features or refactors.
  • Preferred: Experience with multi-region websites, performance optimization, and data privacy/security standards.
  • Preferred: Experience using BigQuery with GA4 exports to analyze usage trends, retention, conversion funnels, and performance issues.
