Jobs via eFinancialCareers Overview
Kensho is S&P Global's hub for AI innovation and transformation. With expertise in Machine Learning and data discovery, we develop and deploy novel solutions for S&P Global and its customers worldwide. Kensho's solutions and research focus on speech recognition, entity linking, document extraction, automated database linking, text classification, natural language processing, and more. The Vector Team at Kensho is focused on designing and deploying production-grade machine learning systems that power our next-generation retrieval-augmented generation (RAG) pipelines. We specialize in building robust retrieval systems, scalable embedding infrastructure, and tightly integrated LLM pipelines that leverage unstructured data sources. Our mission is to make complex unstructured data easily discoverable and actionable by building intelligent, retrieval-driven systems that enhance enterprise search, question answering, deep research, report generation, and knowledge discovery experiences across S&P Global platforms. We are seeking a mid-level Machine Learning Engineer to help develop and scale RAG systems across the company. This is a hands-on, full-lifecycle ML role with a strong emphasis on retrieval models, LLM orchestration, and system-level thinking. What You\'ll Do
Design and implement end-to-end RAG pipelines that integrate embedding models, vector databases, and data retrieval agents Build and optimize retrieval systems over large-scale proprietary datasets using advanced embedding techniques Develop LLM-based solutions that orchestrate retrieval, generation, and ranking to deliver high-quality, context-aware responses Investigate and solve challenges in vector search, chunking and indexing strategies, and GraphRAG Work closely with Product and Design teams to build ML-based solutions that enhance user experiences and meet business objectives Collaborate closely with the ML Operations team to create automated solutions for managing the entire ML systems lifecycle, from initial technical design to seamless implementation Who You\'ll Need
