DataScientistII

Alexa Smart Home is re-imagining how customers interact with and control their smart home devices. We process hundreds of millions of customer actions weekly across diverse device types, manufacturers, and APIs — and we're looking for a Data Scientist II to help us drive customer experience improvements, uncover insights, and build intelligent AI/ML-powered solutions at massive scale. As a Data Scientist on the Alexa Smart Home team, you will develop machine learning models, analytical frameworks and Gen-AI powered solutions that improve product quality, inform strategic decisions, and enable proactive detection of customer experience issues across the smart home ecosystem. You will work with large-scale behavioral and interaction datasets, design experimentation frameworks, and partner with engineering, product, and science teams to deliver data-driven solutions that directly impact millions of Alexa customers worldwide. This role offers the opportunity to work on cutting-edge problems — from building AI/ML solutions that predict and prevent customer-facing issues, to designing analytics systems that surface actionable insights for improving smart home reliability. Key job responsibilities • Design and implement AI/ML models, anomaly detection systems, and statistical frameworks to analyze customer interactions, identify emerging issues, and drive measurable improvements across the smart home ecosystem. • Own the full lifecycle of model development — from exploratory analysis and feature engineering through deployment, monitoring, and continuous improvement. • Partner with product, engineering, and science teams to translate complex business and technical problems into scalable, production-ready data science solutions. • Design and run rigorous experiments (A/B testing, causal analysis) to measure the impact of product and quality improvements and guide strategic decisions. • Develop scalable analytical solutions for impact measurement, KPI development, metric inte
