Job Description
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 US expansion and best-in-class retention driven by deep workflow adoption.
What You'll Work On
- Lead cross-functional projects by defining and designing systems, building proof of concepts, and delivering new service functionality including APIs, data processing, and automation while collaborating with Product and Clients
- Backend and web development on the 9fin platform, focusing on backend services and web application tools
- Senior IC responsibilities: run code reviews, mentor developers, and provide leadership in research and experimentation with new technologies for feature and product development
- Improve the codebase through automation, refactoring, and documentation where most impactful
- Work across diverse domains: complex financial data modelling, access control business logic, environmental and emission data, ML/AI prediction service integration, data visualisation, and automation systems
- Cross-functional collaboration: work with financial, legal, and editorial colleagues to deliver high-quality information and feedback to engineering teams. Break down complex projects for non-technical audiences
- Developer velocity: leverage managed automated preview environments, feature flags, and well-maintained non-production environments to move quickly, gather feedback, and iterate
Our Stack
- Python (dominant backend language)
- Flask & FastAPI
