• Develop and train machine learning algorithms to dynamically identify and prioritize high-value inventories for Real-Time Bidding (RTB) buyers. Continuously explore and reassess previously underperforming inventories to capture opportunities when buyer demand shifts positively.
• Utilize existing machine learning infrastructure, and enhance it as needed, to support the optimization goals. Ensure the infrastructure can handle the scalability and efficiency requirements for processing high-throughput, low-latency bid requests.
• Design, execute, and oversee experiments to test different optimization strategies. Ensure offline estimations closely mirror online revenue estimations using techniques such as counterfactual estimation and inverse propensity score methods. Perform advanced statistical analysis on experiment results to fine-tune the algorithms and improve their performance
• Collaborate closely with other engineering teams to ensure a robust data pipeline such that data is logged and aggregated efficiently and effectively. Ensure that the ML models can effectively leverage this data in bidder technology
• Mentor and guide a diverse team of world-class engineers, fostering an “engineering excellence” culture through the adoption of state-of-the-art tools, risk-driven testing, explainable systems, and rigorous code reviews.
