Data Scientist Markets

About the Role

The Markets team is responsible for what gets listed on Polymarket, how those markets are structured, and whether they actually work. That means thinking hard about liquidity, market design, and what separates a market that generates real price discovery from one that sits dead. This role sits inside that team as the dedicated data scientist, owning the analytical layer that informs nearly every decision they make.

Right now, a lot of that work is manual, ad hoc, or not happening at all. We need someone who can build the infrastructure for understanding market health, model the dynamics that drive liquidity, and help the team make smarter calls on what to list, how to reward liquidity providers, and when a market is broken. You will not be handed a backlog of tickets. You will be expected to identify the questions that matter, go answer them, and come back with something decision-ready.

This is a high-ownership role for someone who thinks seriously about how markets work. If you have spent time at a prediction market, a trading firm, or a fund where you were close to market structure questions, this will feel familiar. If you want to do data work that is abstract from real decisions, this is not the right fit.

What You'll Do

• Model liquidity dynamics across markets to identify what drives healthy order flow and inform how we structure and adjust liquidity rewards.

• Build and maintain recurring reports on market health metrics so the team has a clear, ongoing view of what is working and what is not.
