I manage a network of roughly 20,000 publisher sites and need an extra set of expert hands to keep our monetisation stack humming. The day-to-day work revolves around hunting down and fixing anything that prevents video, banner, or native inventory from serving flawlessly through Prebid solutions. Here is what you will actually be doing for us: • Investigate issues reported by publishers or surfaced in our dashboards (creative not rendering, long auction latency, targeting mismatches, etc.) • Trace the problem through Prebid.js integrations, Google Ad Manager configurations, and whichever third-party wrappers or SSP connections are involved. • Implement and verify fixes directly in the header bidder setup or in GAM line-items when granted access, documenting the change so our internal team can follow the history. • Provide concise root-cause reports and suggest preventive best practices that can be applied at scale across similar sites. Acceptance criteria for every ticket you touch: 1. The ad unit in question renders correctly in a clean browser session. 2. Bid response and auction timings fall within normal benchmarks (<1 s for banners, <2 s for video). 3. Targeting keys populate as expected in GAM’s ad-server call. 4. A brief, one-page summary outlines what broke, how you fixed it, and what we should watch next time. We value clear communication, reproducible testing steps (Charles, DevTools, hb analytics), and code-level familiarity with Prebid.js adapters. If you’re comfortable jumping between vast site portfolios and still keeping meticulous notes, you will fit in perfectly. This is an ongoing engagement with plenty of room to grow alongside our support capacity expansion.
