As a Principal Engineer in Corporate Technology, you'll be empowered to shape the future of engineering across platforms that underpin our finance, risk, compliance, and regulatory operations. With nearly half of all Australian transactions flowing through our systems, this is your opportunity to work on innovative projects that directly contribute to keeping Australians safe from financial crime.

Financial Crime is the largest data consumer in the bank and the pumping heart of its decision systems. We process millions of transactions per hour and protect 14 million customers nationwide.
If you're passionate about leading innovative technology initiatives that create meaningful customer and internal experiences, this is your chance to drive lasting impact.
Our goals are clear:
* Build systems to detect threats and take action early
* Utilise real-time intelligence to identify economic crime
* Operational excellence through data and AI
