Senior Applied Scientist - Predictive Scoring, AWS Marketing Science

Senior Applied Scientist

As a Senior Applied Scientist specializing in lead scoring and deep learning modeling, you will tackle complex challenges in machine learning and deep learning to redefine how our business engages with customers. You will design and deploy high-impact models that drive customer segmentation, adaptive recommendations, and predictive lead and account prioritization. Leveraging your expertise in deep learning, representation learning, and general modeling, you'll help build solutions that directly influence business outcomes, collaborating with cross-functional teams to turn novel research into scalable, production-grade systems.

Key job responsibilities:

• Design and deploy predictive lead scoring models to optimize customer acquisition, conversion, and retention strategies using advanced techniques like survival analysis, graph networks, or transformer-based architectures.
• Architect end-to-end ML pipelines for large-scale deep learning models, including data preprocessing, distributed training, model optimization, and real-time inference.
• Publish research, file patents, and stay ahead of industry trends in the marketing science, propensity modeling, and customer journey prediction domains.
• Innovate in multi-modal modeling (text, graph, behavioral, and temporal data) to enhance scoring accuracy across account and lead levels.
• Conduct rigorous A/B testing, causal inference, and counterfactual analysis to measure model impact and iterate rapidly.
• Collaborate with MLOps engineers to streamline model deployment, monitoring, and retraining using tools like AWS Sage Maker, or MLflow and other internal tools.
• Participate in science reviews to raise the science bar in our organization. This includes reviewing your work and the work of others.
• Mentor junior scientists on ML methodology, experimentation design, and production best practices.
• Define offline and online evaluation frameworks; establish success metrics tied to business outcomes (conversion rates, pipeline generation).

About the team:

The AWS Marketing Science team builds the ML models and measurement systems that drive marketing decisions across Amazon Web Services. We own incrementality and valuation, ROI measurement, marketing attribution, propensity scoring, account and lead clustering, and next-best-action models. Our work directly influences how AWS allocates marketing spend, targets accounts, and measures effectiveness across billions in pipeline.
