Overview

Ad Tech Developer – Header Bidding (Remote)

MonetizeMore is seeking an Ad Tech Developer with in-depth expertise in header bidding to build, optimize, and scale programmatic monetization for premium publishers. You’ll own end-to-end header bidding implementations (with a heavy focus on Prebid.js), improve auction performance, and partner with product, yield, and publisher success teams to deliver revenue-lifting results with excellent user experience.

What You’ll Do

Design & implement header bidding stacks using Prebid.js (web) and related wrappers; configure bidders, floors, price granularity, userId modules, and analytics
Customize & extend adapters / modules (e.g., userId, analytics, consent) and contribute clean, documented JavaScript / TypeScript code
Integrate with GAM / Ad Manager (GPT) : line item strategy, key-values, creative templates, and troubleshooting of delivery and competition
Optimize auctions & latency : tune timeouts, s2s vs. client, floors, ad refresh logic, and page performance (CLS / LCP / INP / Core Web Vitals)
Run experiments : A / B test bidders, formats, and page placements; build dashboards to track impact (e.g., eCPM, viewability, fill, latency)
Debug complex issues across browser, network, and auction layers (DevTools, HAR / Waterfall, Charles / Proxyman); resolve revenue dips & bidder errors
Implement privacy & compliance : IAB TCF, GDPR / CCPA / CPRA, CMP integration, consent storage, and geo-specific behaviors
Work with partners : SSPs, exchanges, ID providers, and analytics vendors to launch new demand and troubleshoot
Ship quality safely : use Git, CI / CD, code review, and observability to keep releases fast and reliable
Document & mentor : write clear runbooks and help level up teammates

What You’ll Bring

3–6+ years of front-end or full-stack experience with a strong JavaScript foundation (TypeScript a plus)

2–4+ years hands-on with header bidding (Prebid.js required); experience with s2s / managed wrappers (e.g., Prebid Server, Amazon TAM / UAM) is a plus

Solid understanding of Google Ad Manager (GAM / GPT) setups, line items & creatives, key-values, targeting, and delivery debugging

Working knowledge of programmatic concepts : OpenRTB, floors, auction dynamics, user sync / ID, brand safety, and viewability

Familiarity with privacy frameworks & CMPs (IAB TCF v2.x, GDPR / CCPA / CPRA) and consent-aware ad serving

Performance tuning for Core Web Vitals and modern build tools (Webpack / Vite / Rollup)

Comfort with Chrome DevTools, network waterfalls, and log-driven debugging; bonus points for Node.js, Cloud Functions, or simple backend endpoints

Data fluency : basic SQL or BI tools (Looker / Data Studio / BigQuery) for revenue & latency analysis

Clear communication with both technical and non-technical stakeholders; bias for automation and measurable outcomes

Nice to Have

Experience with app / webview monetization, AMP, or SPA frameworks (React / Vue / Svelte)

Prebid analytics adapters or custom reporting pipelines

Experience with ads.txt / app-ads.txt, sellers.json, supply chain object

Knowledge of brand safety & IVT controls, creative QA, and MRC viewability standards

Exposure to video (IMA / OMSDK, Prebid Video, VAST / VPAID / VMAP) or CTV / OTT

Knowledge in Python and NoSQL is a plus

Impact at scale across a large publisher network

Smart, low-ego teammates and a culture of experimentation
