Machine Learning Engineer

Who We Are

Kensho is a 120-person AI and machine learning company within S&P Global. We provide ML and AI solutions centered around providing innovative solutions to meet the challenges of some of the largest and most successful businesses and institutions. Our toolkit illuminates insights by helping the world better understand, process, and leverage messy data. Specifically, our solutions involve natural language processing (NLP) and include speech recognition (ASR), entity linking, structured document extraction, record linkage, text classification, and more. We are continuously expanding our portfolio and are looking for passionate people to help us build and deploy state-of-the-art models across a variety of domains!

About Team

Kensho Link is a machine learning service that allows users to map entities in their datasets with unique ID numbers drawn from S&P Globals world-class company database with precision and speed. Link started as an internal Kensho project to help S&P Global Market Intelligence and CapIQ integrate datasets more quickly into their platform. It uses ML based algorithm trained to return high quality links, even when the data inputs are incomplete or contain errors. Link leverages a variety of NLP and ML techniques to process and link millions of company entities in hours. As a team, we have expertise in classical ML algorithms and modern LLM-based tech stacks like RAG systems.

About The Role

As a Machine Learning Engineer, you will have end-to-end ownership of the Link application, driving its development and success. This role is perfect for you if you thrive on creating ML models and have a keen interest in the software engineering aspects of machine learning ( MLOps ). For example, y our responsibilities will include:

Model deployment and optimization

Debugging performance discrepancies between online and offline environments

Ensuring feature synchronization

Optimizing memory and compute resources

Scaling ML systems for maximum efficiency

Why Join Us?

We are continuously expanding our portfolio of projects and are eager to find talented engineers who are excited about building and deploying state-of-the-art ML systems. We are seeking a mid-level Machine Learning Engineer who can help accelerate and refine our ML development cycle, setting new standards for prototyping, building, and maintaining cutting-edge ML solutions.
