Do Work That Matters:

Be part of the team that helps CommBank make better decisions. Risk Management partners across the Group to identify, assess and manage risk, protecting our customers, strengthening the bank and enabling sustainable growth. Join a collaborative team where you’ll solve complex challenges, influence strategic decisions, and use data, insights and innovation to make a meaningful impact.

In this role, you’ll support a newly created capability focused on validating financial crime models as the bank moves from traditional rule-based alerting towards more modern machine learning approaches. You’ll apply strong technical judgement in a highly regulated environment, partnering with stakeholders to assess complex models and strengthen model risk outcomes.
