About the role

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
