Senior Staff Software Engineer- Search Quality

The Role : As a Search Quality Engineer, you sit at the heart of this transformation. You arent just building a search engine; you are building the contextual backbone of the entire company. You will own the quality of results for two distinct but deeply connected "users": The AI Agent: Optimizing the retrieval layer that allows LLMs to reason over data they weren t trained on, ensuring they have the "ground truth" needed to synthesize accurate, high-stakes business actions. The Human User: Improving the traditional search experience so employees can find assets and answers through intuitive, high-recall interfaces. The Technical Challenge This isnt a solved problem. You will be tackling "Search" in its most evolved form: Hybrid Retrieval: Balancing traditional keyword-based search (for exactness) with semantic vector search (for intent). Dual-Optimization: Fine-tuning ranking models that satisfy both human readability and LLM-ready context. High-Stakes Accuracy: In a world of Agents, poor search quality leads to hallucinations. You will build the guardrails and relevance scoring that ensure our AI stays grounded in reality. Data Heterogeneity: Connecting the dots across structured SQL tables, unstructured docs, and real-time business metrics. Why This is the Place to Be You will have a front-row seat to the Agentic revolution. If you want to solve the hardest problems in data discovery and see your work power the decision-making of thousands of people, let s talk. What We re Looking For The IR Specialist: You know your way around Lucene/Elasticsearch, embeddings, and ranking algorithms. The Quality and Metrics Obsessive: You understand that "relevance" is subjective and love building evaluation frameworks (human-in-the-loop and LLM-based) to measure it. You are obsessed with relevance metrics (nDCG, MRR, Precision@K). The Bridge Builder: You re excited to apply traditional Information Retrieval (IR) wisdom to the cutting-edge world of Retrieval-Augmented Generation (RAG).
