What You'll Be Doing

Risk Monitoring & Limits Management

• Monitor real-time and end-of-day market risk exposures across liquidity management activities, spanning spot, perpetual swaps, dated futures, vanilla options, exotic payoffs with KI/KO features
• Track and manage Greeks (delta, gamma, vega, theta, rho) across various trading desks; ensure hedging activity keeps net Greeks within approved limits
• Maintain and enforce stop-loss limits at the desk, strategy, and individual trader level; identify breaches promptly and coordinate effective escalation and resolution
• Monitor margin utilisation and collateral efficiency across venues; flag concentration or margin call risk before it materialises
• Oversee liquidation risk and auto-deleveraging (ADL) exposure for leveraged positions; work with traders to manage positions ahead of critical margin thresholds

Risk Framework & Methodology

• Continuously develop and enhance the market risk framework for the market making desk, including VaR models, Expected Shortfall, stress testing, and scenario analysis calibrated to crypto market dynamics
• Own PnL attribution and reconciliation — decompose daily trading PnL into Greeks, carry, and residual components to validate model accuracy and identify unexplained P&L
• Define and maintain a comprehensive suite of risk limits including notional limits, Greeks limits, stop-loss thresholds, concentration limits, and venue-level position limits; perform periodic data-driven reviews
• Evaluate market risk for new products, strategies, and client structures prior to launch, including bespoke structured products and barrier option payoffs
• Develop and refine margin parametrisation models to support efficient capital usage while maintaining robust risk controls

Stakeholder Engagement & Reporting

• Understand the market, discuss risk exposures and concerns with senior risk managers and traders
• Produce and review high-quality daily, weekly, and monthly risk reports for the desk head and senior leadership, presenting complex exposures and risk metrics clearly to both technical and non-technical audiences
• Lead post-mortem reviews on market risk incidents, stop-loss breaches, or significant mark-to-market events; ensure root causes are identified and controls updated
• Partner with Trading, Structuring, Technology, and Finance teams to design and implement risk system improvements, automate monitoring workflows, and improve data quality
• Engage with regulators and external auditors on market risk matters related to the liquidity management business as required
