  • Build intelligent optimization systems for ad placement, frequency, segmentation, and pricing.
  • Develop backend services and automation tools for real-time monetization decisions.
  • Analyze monetization performance using large-scale data and implement data-driven improvements.
  • Optimize SDK integrations, latency, memory usage, and overall ad performance.
  • Work closely with Growth, Product, and Data teams to continuously increase LTV and user monetization.
  • Research and implement new monetization technologies, bidding strategies, and demand sources.
  • Increase overall monetization performance across millions of users.
  • Maximize fill rate, eCPM, advertiser competition, and total revenue.
  • Build the next generation of the monetization engine using automation and AI.
  • Deliver measurable business impact through engineering excellence.
Required Qualifications:
  • Ad-monetization domain (25%) — deep understanding of RTB, Header Bidding, Waterfalls, Fill Rate, eCPM/CPM optimization, and advertiser demand.
  • Ad mediation platforms + mobile advertising SDKs (20%) — hands-on integration and optimization.
  • Software development (20%) — strong backend, distributed systems, APIs, and performance optimization.
  • Mobile development (15%) — Android and/or iOS.
  • Analytical, data-driven optimization (12%) — analyze large-scale monetization data and implement data-driven improvements.
  • High-scale consumer app experience (8%) — experience with high-scale consumer applications reaching millions of users.
Nice To Have:
  • Hands-on with AppLovin MAX, Google Ad Manager, AdMob, Unity Ads, or IronSource.
  • Building internal optimization engines using AI or Machine Learning.
  • Familiarity with attribution, user segmentation, A/B testing, and predictive monetization models.
