**Location:** New York, NY
**Role:** Data Science
**Skills:** Python, SQL, market structure, liquidity modeling, Statistical Modeling, order books, automated market makers, clob, decentralized exchange design
**Posted:** 2026-07-30

> Data Scientist embedded in Polymarket's Markets team, modeling liquidity dynamics, auditing listings, analyzing market health, and building decision frameworks for prediction market design and liquidity incentives. Requires deep market structure knowledge, Python/SQL expertise, and end-to-end ownership of analyses that directly inform listings and rewards.

## Job Description

## Responsibilities
- 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.
- Audit new market listings using historical and comparable market data to recommend approval, structural adjustments, or rejection.
- Analyze underperforming markets to diagnose root causes, whether that is poor resolution criteria, thin liquidity, bad timing, or something else entirely.
- Partner with the Markets team weekly to scope incoming data questions, prioritize them, and deliver outputs that lead to a decision, not just a chart.
- Develop frameworks for evaluating what makes a market work, so those standards can be applied consistently across listings and product decisions.
- Identify gaps in our current data collection or instrumentation and work with engineering to close them where it matters for market analysis.

## Requirements
- Strong Python proficiency for data analysis, statistical modeling, and working with large datasets.
- SQL knowledge is a must.
- Deep, working knowledge of market structure. You should be able to reason about order books, spreads, liquidity provision, and market design tradeoffs without needing a primer.
- Experience owning analyses end to end, from scoping an ambiguous question to handing a stakeholder something they can act on.
- A track record of building models that capture real complexity, not just descriptive summaries. You can explain your assumptions and where your model breaks.
- Comfort working embedded in a non-data team where you are setting your own agenda and managing your own priorities.

## Nice-to-Haves
- Experience at a prediction market platform, trading firm, or fund where you were close to market structure or liquidity questions.
- Familiarity with automated market makers, CLOB mechanics, or decentralized exchange design.
- Experience building or evaluating liquidity incentive programs.

## Benefits
- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup: new MacBook Pro, big display, & accessories
