Do work that matters

As a Senior Manager in our Credit Model Validation team, you’ll join a talented group of credit risk modelling experts, driving excellence in model validation.

You’ll play a key role in shaping the future of our credit models, ensuring best practice and alignment with our customer and regulatory expectations.

As part of a highly skilled quantitative team serving all lending businesses across the CBA Group, you will lead critical validation projects for credit risk models. You will also help shape and deliver strategic initiatives that strengthen modelling frameworks and uplift the agility and efficiency of validation activities.

This will be a permanent full-time opportunity.

As a key member within the Credit Model Validation chapter, you will lead technical validation activities, deploy advanced analytical methods and tools, and reinforce strong risk management practices throughout the entire model lifecycle. You will deliver comprehensive validation reviews from end to end, mentor and develop team members, and play a pivotal role in enhancing our validation frameworks and methodologies. You will set high standards of technical excellence, exercise sound judgement, and foster strong, effective engagement with stakeholders across the Group.

Your core responsibilities will include

• Model Validation & Technical Leadership – Lead the design and execution of comprehensive validation plans assessing data quality, modelling methodologies, model performance and regulatory compliance.
• Stakeholder Engagement – Engage proactively with model developers/owners, business stakeholders, auditors and regulators to communicate findings, risks, and recommendations. Present insights to internal technical forums, governance committees and/or regulatory meetings.
