• Build volatility and correlation models for derivatives, including calibration, backtesting, and ongoing model validation.
• Develop and run stress-testing frameworks including historical scenarios, hypothetical shocks, and reverse stress tests.
• Design and tune auto-liquidation logic.
• Use AI tools to accelerate model development, coding, and research and validate outputs against established risk models.
• 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.
