About the RolePolymarket is hiring a Quantitative Risk Analyst to design and implement enterprise-scale risk models at the heart of our clearing operation. You'll own models for market risk, volatility and correlation of derivatives, stress testing, and automated liquidation - the systems that keep the platform solvent and users protected in fast-moving markets.
This is a hands-on role: you'll be building models in production code, not just specifying them. We expect you to work fluently with AI tools for development and research - and to be the skeptic in the room, pressure-testing AI-generated models and code against well-established risk frameworks before anything ships.
What You'll Do- Design, implement, and maintain enterprise-scale risk models covering market risk, margin, and counterparty exposure for a clearing organization
- Build volatility and correlation models for derivatives, including calibration, backtesting, and ongoing model validation
- Develop and run stress-testing frameworks: historical scenarios, hypothetical shocks, and reverse stress tests
- Design and tune auto-liquidation logic - trigger thresholds, liquidation waterfalls, and safeguards against cascading liquidations
- Use AI tools extensively to accelerate model development, coding, and research - and rigorously validate AI outputs against established risk models before deployment
- Monitor model performance in production, investigate breaks, and iterate quickly
- Partner with engineering, trading, and product teams to embed risk controls into platform architecture
- Document model assumptions, limitations, and validation results to an audit-ready standard
What We're Looking For- 5-7 years of quantitative risk experience at a clearinghouse, exchange, prime broker, trading firm, or similar
- Proven expertise designing and implementing risk models at enterprise scale - production systems, not just research prototypes
- Deep experience modeling volatility, correlation, option skews, and option pricing at scale for trad-fi derivatives, perpetuals, and fully collateralized event contracts
- Hands-on experience with market risk modeling, stress testing, and auto-liquidation mechanics in a clearing context
- Strong fluency with AI-assisted development and coding, paired with the judgment to pressure-test AI outputs against well-established risk models and catch what looks plausible but is wrong
- Expert-level Python (NumPy, pandas, SciPy; solid software engineering practices)
- Advanced degree in a quantitative field (math, statistics, physics, financial engineering, CS) or equivalent experience
- Strong mathematical foundation in stochastic calculus and linear algebra
- (Plus) C# and/or C++ for performance-critical or production systems
- (Plus) Familiarity with crypto market structure, perpetuals, or prediction markets
- (Plus) Experience with CCP risk frameworks (CPMI-IOSCO PFMI, default management, margin methodology)
- (Plus) Experience building real-time risk systems
Benefits- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup: new MacBook Pro, big display, & accessories
