Responsibilities:
KEY RESPONSIBILITIES
- 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 optimization goals, ensuring scalability and efficiency for processing high-throughput, low-latency bid requests.
- Design, execute, and oversee experiments to test different optimization strategies, ensuring offline estimations closely mirror online revenue estimations using techniques such as counterfactual estimation and inverse propensity score methods.
- Perform statistical analysis on experiment results to fine-tune algorithms and improve performance.
- Collaborate with other engineering teams to ensure a robust data pipeline, logging, and aggregating data efficiently and effectively, allowing ML models to leverage this data in bidder technology.
- Participate in fostering an “engineering excellence” culture through the adoption of state-of-the-art tools, risk-driven testing, explainable systems, and rigorous code reviews.
This is a remote-first role, requiring:
- Ability to work Pacific time zone hours.
- Willingness to travel to Orange County for in-person meetings 1-2 weeks per quarter
