Optimize features, ML models, and infrastructure for traceability, observability, quality, freshness, and low latency and scalability of training and inference.
Manage feature data, ML workflows, and ML models, making use of modern machine learning operations, dashboards, and monitoring for robust and observable life cycle management.
Conduct deep analytical investigations to uncover insights and drive data informed decisions about ad delivery system operation and performance.
Participate in on-call rotation and provide operational support for data pipelines and ML-driven ad serving.
Mentor and coach ML Scientists and Engineers, fostering a culture of learning and technical excellence.
