About the role

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.

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.

Benefits

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.
