Who We Are

Job Overview:

Key Responsibilities:

• Lead independent quantitative validation of FinCrime, AML, AI/ML, and Generative AI models across OKX.
• Perform conceptual soundness and data integrity reviews — assess model theory, methodology, assumptions, data quality, lineage, and applicability to crypto-specific risk typologies.
• Perform quantitative model performance testing — back-testing, sensitivity analysis, threshold tuning, drift detection, and outcomes analysis — with additional fairness, explainability, and adversarial robustness assessments for AI/ML models.
• Apply effective challenge to 1LOD model owners and developers; document validation findings, model limitations, and required remediations.
• Author validation reports suitable for governance committees and regulatory inspections.
• Track validation findings through remediation closure; participate in annual and triggered revalidation cycles; contribute to and maintain the enterprise Model Inventory (entry, classification, materiality assessment).
• Ensure validations meet OKX's Global Model Risk Policy and applicable global regulatory obligations — including AI governance frameworks where ML/AI components apply.
• Contribute to the build-out of validation playbooks, model inventory standards (including AI/ML risk tiering), and operational frameworks — including OKX's AI Governance framework — under the direction of the Global Head of MRM.
• Partner with model developers / owners, Compliance, Tech, Internal Audit, and Legal — while preserving organizational independence from model development.

Qualifications:

• Master's or Ph.D. in Quantitative Finance, Statistics, Mathematics, Econometrics, Computer Science, or another quantitative field — or equivalent depth of professional experience.
• 8+ years of relevant quantitative experience, of which at least 3 years in independent model validation (2LOD) at a financial institution, fintech, or crypto firm.
• Demonstrated experience validating risk models — such as credit, market, FinCrime, fraud, or AML.
• Hands-on experience validating statistical, machine learning, AI/ML, and Generative AI models — hypothesis testing, performance benchmarking, fairness testing, drift detection, explainability, and adversarial robustness.
• Working knowledge of MRM and AI governance frameworks — SR 11-7 / SR 26-2, EU AI Act, US Treasury FS AI RMF, NIST AI RMF, or equivalent.
• Strong programming proficiency in Python, SQL, and R.
• Experience with cloud / big-data platforms — BigQuery, Snowflake, Databricks, Hadoop/Hive, MaxCompute, or equivalent.
• Excellent written and verbal communication — capable of authoring formal validation reports and presenting findings to senior risk committees, regulators, and external auditors.

Preferred Qualifications:

• Experience working with crypto exchanges, DeFi platforms, or blockchain analytics firms.
• Hands-on experience with AML / FinCrime model validation techniques.
• Hands-on experience with on-chain analytics tooling — Chainalysis, TRM Labs, Elliptic, or equivalent. Experience validating crypto-native risk models.
• Professional certifications: CFA, FRM, CAMS, CCAS (one or more).
• Familiarity with smart contract risk analysis, DeFi protocol risk, and stablecoin flows.
• Experience with Generative AI / Agentic AI model validation under emerging US Treasury FS AI RMF and NIST AI RMF guidance.

Reporting and Location

Who We Are

About The Team

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
