Description "We see our customers as invited guests to a party, and we are the hosts. It's our job every day to make every important aspect of the customer experience a little bit better." - Jeff Bezos, Founder & CEO. We didn’t make Amazon a trillion-dollar company, our customers did and we want to ensure that our customers always have a positive experience that keeps them coming back to Amazon. To help achieve this, the Worldwide Defect Elimination (WWDE) team, within Amazon Customer Service, relentlessly focuses on maintaining customer trust by building products that offer appropriate resolutions to resolve issues faced by our customers.

You will leverage a spectrum of scientific techniques across both classical ML and Natural Language Processing/Generative AI (NLP)/GenAI to comb over our billions of customer interactions (using a combination of media). In this role, you will collaborate with cross-functional teams (Product, Engineering, Program) and contribute to advancing the state of defect elimination research. This candidate should have a knack for leveraging AI to translate complex data insights into actionable strategies and can communicate these effectively to both technical and non-technical audiences. Key job responsibilities - Develop ML/GenAI-powered solutions for automating defect elimination workflows. - Implement scalable and efficient scientific solutions in production environments. - Design and implement robust metrics to evaluate the effectiveness of ML/AI models. - Perform statistical analyses and statistical tests, including hypothesis testing and A/B testing. - Recognize and adopt best practices in reporting and analysis: data integrity, test design, analysis, validation, and documentation.
