Quantitative Validation Specialist - Financial Markets & Treasury

About the role

A tier-one Australian bank is recruiting a Quantitative Validation Specialist for its Financial Markets risk team, embedded in a dedicated model risk division.

• Evaluate IRRBB models and align quantitative frameworks with APRA standards such as APS 116, APS 117 and CPS 226.
• Turn complex quantitative findings into clear, persuasive narratives for front-office heads and risk leadership.

Required profile

• Demonstrable experience in quantitative finance within investment banking, capital markets or model risk.
• Advanced tertiary qualification in Applied Mathematics, Quantitative Finance, Econometrics, Physics or an aligned quantitative field.
• Experience of at least 2 years.

Required skills

• Solid grasp of derivative valuation, volatility structures and market risk mechanics across Rates, FX or Commodities.
