Head of Market Risk

About the Role

Polymarket is looking for a Head of Market Risk to own the firm's market risk framework across both our Futures Commission Merchant (FCM) and Derivatives Clearing Organization (DCO). This is a senior, hands-on leadership role responsible for identifying, measuring, monitoring, and controlling the market risks arising from cleared member portfolios and the risks the clearinghouse mutualizes as a central counterparty.

The ideal candidate has direct trading and risk management experience and understands how markets behave under stress — how liquidity evaporates, how volatility regimes shift, and how macro events move prices. That intuition must be paired with the rigor to set, calibrate, and defend the margin and risk parameters that keep the FCM and clearinghouse safe, and the communication skills to translate complex exposures into clear, decision-ready terms for the Risk Committee, Board, regulators, and clearing members.

What You'll Do

• Own the end-to-end market risk framework for the FCM and DCO, including risk appetite, limit structures, escalation triggers, and the policies that govern them

• Serve as the primary market-risk voice to the Risk Committee and Board, presenting exposures, limit utilization, stress results, and emerging risks in clear, actionable terms

• Ensure the framework meets CFTC requirements and DCO Core Principles and stands up to regulatory and internal-audit scrutiny
