Walmart

The Principal Data Scientist will apply and develop statistical modeling techniques, optimization methods, and ML techniques to build efficient and scalable models at Walmart scale. This role involves collaborating with business and engineering counterparts, defining model metrics, tracking business impact, and publishing research in top-tier conferences. The focus is on leveraging generative AI, ML, deep learning, and computer vision to improve customer search and e-commerce experiences.

The role focuses on designing and building multi-modal evaluation frameworks and AI-as-a-judge systems, primarily for generative AI content in Extended Reality experiences. It involves fine-tuning Vision-Language Models and Reward Models, leading experimentation with causal inference, orchestrating RLHF strategies, and collaborating on model launch criteria. The role also involves staying current with research in perceptual quality and implementing techniques to detect issues in generated content.
