About this opportunity

Key responsibilities and your contribution

  • Architect and optimize a custom Prebid.js-based header bidding stack
  • Build and maintain high-performance JavaScript integrations running on publisher websites
  • Improve latency, auction efficiency, and yield optimization across ad units
  • Develop and enhance React-based widgets that render dynamic local listings
