These are the cross-cutting problems that don’t belong cleanly to any one team — but that everything else depends on.
Core data model and entity resolution
9fin’s value depends on how well we understand financial entities and the relationships between them — issuers, instruments, deals, counterparties, legal documents. This is hard: data is messy, sources conflict, and the model has to serve analytics, AI, and product simultaneously. You’ll own the decisions that shape this foundation and hold the standard for how we model and resolve financial data at scale.
Foundational architectural decisions
When a decision is big enough to affect multiple teams and long-lived enough to be hard to undo, it lands with you. You’ll write the RFCs, facilitate the debate, make the call, and be accountable for the outcome.
You’ll work closely with the Heads/Directors of Analytics, AI, Platform, and Product Engineering — not to run their domains, but to raise the bar across all of them.
