Overview
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 (heavy 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
Why MonetizeMore
- Remote-first culture with flexible work hours
- Impact at scale across a large publisher network
- Smart, low-ego teammates and a culture of experimentation
- Competitive compensation, performance bonus, home-office stipend, and learning budget.
