• Apply cutting-edge ML approaches (e.g., reinforcement learning, deep learning for ranking) to improve ad performance
• Build scalable infrastructure to support real-time ad decisioning across millions of requests per day
• Conduct rigorous experiments (A/B and multivariate tests) to measure model impact on business KPIs
• Continuously improve ETL pipelines and monitoring systems to ensure reliable ad delivery
• Collaborate with global teams across product, data, and engineering to launch high-impact ad features
• Stay ahead of emerging technologies and integrate them into our ML stack when they create competitive advantage

COMPETENCIES

• Impact-Oriented: You align ML systems to business outcomes and measure what matters
• Technical Builder: You write clean, production-ready code and architect scalable systems
• Collaborative: You work seamlessly with global teams and communicate complex ideas clearly
• Resilient & Determined: You don’t shy from challenges and drive projects through to impact
