GenAI - Data Scientist (Search, Discovery)

At Proximity Works, we build AI-native products that operate at scale. We're now entering a critical phase—moving beyond baseline functionality to delivering high-quality, delightful user experiences across search, conversational AI, and multimodal systems. This role sits at the intersection of LLMs, search, personalization, and video intelligence, with direct impact on products used by hundreds of millions of users.

What You'll Work On • Improving conversational search quality—making responses not just correct, but intuitive, contextual, and delightful • Contributing to the unification of traditional and conversational search, including routing logic, ranking systems, and cost optimization • Building and integrating ranking and personalization systems, combining user context with query intent • Developing video intelligence capabilities—scene-level understanding, embedding-based retrieval (CLIP and similar), and dynamic content stitching • Working on reasoning over unstructured data (RAG, multi-hop reasoning), especially for high-context domains like sports and content discovery • Designing and iterating on evaluation frameworks to continuously improve quality and performance • Operating in fast iteration cycles, closely aligned with product and engineering teams

Key Problem Areas • Elevating search experience from functional to "magical" • Designing a unified search architecture across modalities and interfaces • Balancing quality, latency, and cost in production systems • Scaling systems while maintaining high standards (the "90 → 95" problem)
