Demonstrated experience in at least one of the following: search/information retrieval, personalized ranking/recommender systems, or generative AI/LLM-based systems.
Holds a PhD or Master’s degree in a relevant field (Computer Science, AI, Data Science, or related), or equivalent industry experience (typically 3-4+ years with a Master’s, or 1+ year with a PhD).
Comfortable working near production systems and collaborating closely with engineers and cross-functional partners.
Brings curiosity and excitement for applying generative AI and LLMs to transform the home-shopping experience.
