Senior IT & InfoSec Engineer

Senior IT & InfoSec Engineer

9fin is the AI platform powering global debt markets — the world's largest asset class at over $145 trillion. Debt markets are vast, global, and mission-critical, yet still run on fragmented data, PDFs, and manual workflows. 9fin replaces this broken infrastructure with a single platform that centralises proprietary credit data, deep analysis, and high-value workflows across global markets.

Today, 9fin powers teams at 300+ blue-chip institutions worldwide, including global banks, asset managers, private equity firms, law firms, and advisors. The business is scaling at exceptional speed, with rapid expansion in the US and best-in-class retention driven by deep workflow adoption.

We're at a defining inflection point. With proven product-market fit and strong, global market pull, 9fin is accelerating toward becoming the category-defining platform for debt markets worldwide.

The world's largest asset class in fixed income operates with the worst data. Technology has revolutionised the equity markets with electronic trading, quant algos and instantaneous news. However, in debt and fixed income, the picture is completely different. Trades are placed over the phone, news is slow, and information is imperfect. Billions of dollars of capital is allocated to companies, projects and investments all over the world - making the best decisions on where to deploy it requires the best information.

The debt capital markets behave like it's still the 1980s, it is the last to be technologized - our mission is to make it happen. We're rapidly taking market share in the fixed-income data industry with our modern solution that our clients love. 9fin's market-leading technology uses AI to deliver financial, credit & ESG insights more quickly than anyone else. It uses cutting-edge technology to produce fast news and deep-dive predictive analytics. We help our clients win advisory mandates, react to credit trading opportunities faster 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.

As we continue to expand, IT and information security becomes an increasingly important part of how we grow. We work daily with highly sensitive customer information across the company and are committed to ensuring it is protected throughout its lifecycle.
