You'll architect next-generation search and discovery experiences that enhance relevancy, filtering capabilities, and the overall customer journey. You will also contribute to Zappos systems across the new product lifecycle, from buying products, capturing product details, and generating best-in-class product imagery through innovative technical solutions. This includes developing innovative solutions for faceted navigation, personalized product recommendations, and unified catalog data models that serve both brands while maintaining their unique identities. You'll leverage technologies including LLM and ML tooling to push the boundaries of what's possible in e-commerce product discovery while ensuring consistent performance at scale.

A day in the life
Your morning starts with code reviews and identifying a performance bottleneck in a search feature. You lead a technical design review for an ML-based product categorization system to improve search relevancy across Zappos and Shopbop. After analyzing A/B test results from a recent PDP enhancement, you work on integrating LLM capabilities for better product descriptions. Later, you collaborate with UX designers on a faceted navigation system for PLPs and document your approach for a unified catalog data model that preserves each brand's unique customer experience.
