Senior Machine Learning Engineer

The NLP team at Kensho Technologies is at the forefront of designing and applying cutting‑edge machine learning in the domains of natural language processing, natural language interfaces, and information retrieval paradigms over some of the richest and most complex financial and market datasets in the world. We are continuously expanding our portfolio of projects and are looking for passionate researcher‑engineers to help us build and deploy state‑of‑the‑art ML systems! Recently RAG‑based systems that integrate structured and unstructured data are at the core of our team’s projects. These solutions are integrated into the S&P Global platforms, providing users with the ability to find and analyze complex financial data efficiently. The NLP team works closely with the Data, Product, Design, Backend & Frontend teams, and has the full support of our ML Ops and Infrastructure teams. We are seeking a Senior ML Engineer to help accelerate and improve our ML development cycle, continually raising standards of prototyping, building, and maintaining SOTA ML solutions. At Kensho, we believe in flexibility‑first, and give our employees the opportunity to work from where they feel most productive and engaged (must be in the United States). We also value in‑person collaboration, so there may be times when travel to one of our Kensho hubs (e.g., Cambridge, MA or NYC) will be required for team meetings or company events. Kensho states that the anticipated base salary range for the position is 175k - 225k. In addition, this role is eligible for an annual incentive bonus and equity plans. At Kensho, it is not typical for an individual to be hired at or near the top of the range for their role and compensation decisions are dependent on the facts and circumstances of each case.
