This role is ideal for someone who is based in the NYC Metro Area, passionate about building real-world GenAI applications and bringing them into production, while continuously improving performance, reliability, and user outcomes. Responsibilities Deliver GenAI solutions end-to-end Own technical design and implementation of GenAI applications from discovery through production handoff. Build APIs/services that integrate with enterprise systems and analytics platforms. Implement enterprise-grade RAG Design ingestion pipelines for internal content (PDFs, policies, research, dashboards, ticketing, wikis). Build retrieval systems with hybrid search, filtering, re-ranking, query rewriting, and context optimization. Implement permission-aware retrieval aligned to entitlements and data access policies. Establish evaluation and quality controls. Define metrics for retrieval quality and answer grounding (faithfulness, citation accuracy, coverage). Create golden datasets, regression tests, and automated evaluation harnesses.
