About 9fin
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 Opportunity
We are seeking an Engineering Lead with proven experience to help scale our platform, set technical direction, and build a high-performing team that delivers meaningful product experiences. You will be at the center of how we make complex data accessible, reliable, and impactful, guiding engineers to solve high-value challenges across data, product, and infrastructure. Our managers do more than oversee projects. They shape critical decisions that influence every part of product development. We expect our leads to come from a highly technical background, as well as being masters of their craft, able to dive into details, sharpen fundamentals, and continually hone their skills. Cavalry officers must be able to ride horses. You are a skilled engineer with leadership experience, bringing not only a deep love for the engineering craft but also the recognition that your greatest impact comes from enabling others to thrive.
