Data Scientist, Alexa Smart Home

Description 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 integrity validation, and long-term business monitoring.
• Explore and apply GenAI and LLM-based approaches to accelerate insight generation, automate analytical workflows, and solve novel smart home challenges.
• Communicate findings and recommendations to senior leadership through clear data narratives, written documents, and presentations that influence product and business strategy.
• Collaborate with colleagues across science and engineering disciplines for fast turnaround proof-of-concept prototyping at scale.
• Contribute to the broader science community by mentoring analysts, improving data workflows and tooling, and sharing technical work in internal and external forums. A day in the life
• Deep dive into smart home interaction metrics — analyzing trends, failure categories, and model performance across dashboards and datasets.
• Developing code: building packages in Python, writing SQL queries, and deploying ML solutions that Smart Home teams consume.
• Leading or joining working sessions with Product Managers to refine problem statements for new initiatives.
• Exploring new features and model architectures, leveraging AWS services and LLMs to solve smart home-specific challenges.
• Partnering with engineers to align on solution designs and ensure data science insights translate into robust, production-ready systems.
• Owning or co-owning WBR/MBR documents reviewed with Smart Home leadership.
