Role overview
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.
What you will do
- Own the end-to-end data engineering operating model, defining ingestion, orchestration, and warehouse foundations across the entire organization.
- Lead the development of commercial-grade APIs and data feeds, implementing SLA-driven operations and clear schema contracts for global institutional clients.
- Mentor and grow a high-performing data engineering team, shifting from 1-2 to ~4 reports while maintaining a 75% hands-on technical focus.
Who this is a fit for
- Proven experience building and scaling production data platforms using Python, SQL, and modern orchestration tools like Dagster or Airflow.
- Strong architectural fluency in cloud-native environments, specifically across AWS and GCP with practical Infrastructure-as-Code experience.
- High-agency leader who has successfully transitioned data infrastructure from early-stage to growth-stage maturity within a fast-paced startup or scale-up environment.
Why this role is remarkable
- Direct ownership of a critical platform at a $50M Series B scale-up where data is the core product, not just a support function.
- High-impact mission to modernize the world's largest asset class by replacing fragmented, 1980s-era tooling with real-time AI analytics.
- Exceptional culture of high autonomy and execution, working alongside founders who have scaled the company to support firms with $17 trillion AUM.
