About this role
Role overview
About the company
Finance
9fin is the AI-native intelligence platform built for modern credit teams- founded in 2016 by ex-investment bankers Steven Hunter and Huss El-Sheikh to replace the fragmented, manual workflows that have defined debt capital markets for decades by unifying real-time news, structured data, and AI-powered analytics across leveraged finance, distressed debt, CLOs, private credit, ABF, and investment grade. Backed by $250M+ from Spark Capital, Redalpine, and Lakestar, and powering credit teams at 300+ institutions including major investment banks, hedge funds, law firms, and private credit funds across North America, Europe, and Asia-Pacific, the company reached a $1.3B unicorn valuation at its Series C. 9fin careers attract people who sit at the intersection of financial markets expertise and a genuine love of data and technology; 9fin job openings in London and New York are for those who bring intellectual rigour and a product mindset to the challenge of making debt capital markets more efficient and transparent.
