Senior Data Analyst (Growth) in London

Join to apply for the Senior Data Analyst (Growth) role at 9fin. About 9fin: The world's largest asset class, debt, operates with the worst data. Technology has revolutionised equity markets with electronic trading, quant algos and instantaneous news. However, in debt capital markets, the picture is completely different. It still behaves like it's in the 1980s; trillions of dollars of trades are placed over the phone, news is slow, and corporate credit information is imperfect and scattered. Our mission is to change this.

9fin's proprietary technology delivers fast and comprehensive financial, credit, legal & ESG analysis. Our clients are able to make faster, more informed decisions, win more business and most importantly, save time. Our fast-growing list of clients includes 9 of the top 10 Investment Banks, leading Asset Managers, Hedge Funds and Law Firms.

• Define and surface core business metrics (ARR, NRR, churn, LTV, CAC), and own the semantic layer so that stakeholders trust the numbers.
