Role & responsibilities:

We run publisher monetization at scale. Header bidding wrappers, Google Ad Manager setups, Open Bidding yield, floor logic, and the reporting stack behind it. We need someone who can own that end to end, not just ship features on top of it.

You will be the person who knows why a bid did not win, and can prove it with data.

What you will be doing?
Build and maintain our Prebid.js wrapper: adapter integrations, timeout tuning, refresh logic, bid latency
Work with OpenRTB request and response flows. Read a bid stream and tell us what is wrong with it
Manage Google Open Bidding and GAM 360, including line items, key-values, UPR floors, and yield groups
Implement and debug ad tags across display, video, and high-impact formats
Automate reporting through the Google Ad Manager API and Google Analytics API
Ship full-stack: TypeScript and JavaScript on the front, Node on the back
Serve our ad scripts through Cloudflare. Workers, cache rules, edge config
Own our MySQL and Postgres databases: schema design, slow query hunting, indexing,



partitioning
Handle server setup and DNS. Nginx, SSL, subdomain routing, CNAME and TXT records, ads.txt hosting

Preferred candidate profile:
Deep working knowledge of GPT (Google Publisher Tag), both implementation and debugging. This is core to the role and we will test it in detail
Deep working knowledge of VAST and VPAID, again on both implementation and debugging
Real production Prebid.js experience. Not "I read the docs"
OpenRTB 2.5 or 2.6, and how SSPs, DSPs, and exchanges actually talk to each other
Google Ad Manager hands-on, including the GAM API
Comfort across ad formats and their quirks: display, native, video, out-of-page, and app or AMP surfaces
Solid TypeScript and JavaScript, with real browser debugging skill
Node.js backend
MySQL and PostgreSQL with genuine query optimization experience. If your answer to a slow page is "add more RAM", this is not the role
