What you’ll do

• Own the development, testing, and ongoing maintenance of quantitative risk models, including VaR, SVaR, broad-based stress testing, and single-stock stress testing — updating them as market conditions and regulatory requirements evolve
• Write and maintain clear methodology documentation for every model used in day-to-day stakeholder decisions, so the teams consuming your outputs understand what they're working with
• Apply deep knowledge of CIRO 5000 margin rules to model how margin requirements and capital would be impacted under a range of stressed conditions
• Develop production-quality code across multiple programming languages to build, maintain, and improve model infrastructure
• Work cross-functionally with margin, delinquency, and dynamic risk reporting teams to support risk-cognizant decision-making — translating complex model outputs into clear, actionable guidance
• Identify and flag model performance issues proactively, including cases where outputs may be inaccurate or non-meaningful given current market conditions

What they’re looking for

Select a requirement to inspect fit, evidence or application context.

• Someone who understands market context deeply enough to know when a model is producing results that don't make sense — and experienced enough to fix it
• Rigorous about methodology and documentation; you don't consider something done until the next person can understand it without asking you
• Comfortable working independently on hard technical problems; you don't need to be managed through the work, and you know how to prioritize when deadlines are real
• A clear, direct communicator who can bring non-technical stakeholders along without losing precision
• Thoughtful about how you use new tools, including AI — you see them as ways to work better, not as substitutes for the judgement this work requires
• Someone who builds trust with cross-functional partners by being reliable, consistent, and easy to work with even when the subject matter is complex

Helpful, not always essential

• Master’s degree in a quantitative field.
• CFA, FRM, or equivalent professional designation
• Derivatives Fundamentals and Options Licensing (DFOL) certification
• Familiarity with building or contributing to model governance frameworks, including ticketing, prioritization, and model registry infrastructure
• Experience presenting quantitative model outputs and methodology to senior stakeholders or regulators
• Exposure to margin lending, portfolio lending, or credit risk in a brokerage context
