  • Strong understanding of browser performance, async loading, and script execution
  • Experience with AdTech ecosystems (Prebid, GAM, DSPs, SSPs) OR strong adjacent experience (high-scale JS, real-time systems)
  • Familiarity with header bidding concepts (auctions, bid requests, latency tradeoffs)
  • Experience debugging third-party script conflicts and optimizing page performance
  • Ability to work in a fast-moving, product-driven environment

Nice to Have

  • Direct experience with Prebid.js customization or bidder adapters
  • Exposure to analytics, tracking, and attribution systems

Benefits

  • 30 paid days off each year β€” use them for vacation, holidays, or personal time
  • 5 paid sick days, up to 60 days of medical leave, and 6 paid days off for family events like weddings, funerals, or having a baby
  • Partially covered health insurance - after probation
  • Wellness bonus for gym memberships, sports nutrition, and similar needs
