Executive Manager - Multiple Teams

• Sydney Based Location / Hybrid Working

The Opportunity 

Set the technical bar for AI that matters. Lead the craft, stay close to the code and build the standards that help multiple squads deliver trusted AI at enterprise scale.

It’s an exciting time of growth and change at Westpac as we build deeper AI Science capability across Business Banking & Wealth (B&W). This role will sit close to the squads and take accountability for technical design, methodology and capability standards across the portfolio. 

You will challenge solution designs before build, tackle the hardest problems personally and create the systems that help strong technical people become exceptional technical leaders.

Additionally, you will bring clarity where the work is complex: from predictive modelling and decision science to document intelligence, copilots and agentic workflows.

Just as importantly, you will make sure quality, explainability, fair treatment, privacy, security and evidence are built in from the start!

Responsibilities … 

• Convert portfolio priorities into practical technical capability plans across lending, servicing and advice.
• Own the technical design and methodology for complex modelling and agentic AI decisions.
• Set model and agent acceptance criteria, including factuality, unsafe advice and failure-mode testing.
• Lift data quality, leakage prevention, temporal validation, calibration, explainability and fairness across customer segments.
• Build reusable model and agent patterns, shared evaluation systems and disciplined peer-review routines.
• Embed AI risk, privacy and security controls, with clear assumptions, limitations, approvals and material risks.
• Coach AI professionals across squads and grow Craft Senior Managers as credible technical leaders.
• Partner across the AI practice, Technology and Operations to strengthen lifecycle quality, monitoring and recovery.

What you will bring to the table … 

• Deep, hands-on AI Science expertise, with the judgement to set a technical bar and defend it constructively.
• Strong capability in predictive modelling, causal inference and experimentation.
• Practical experience with LLMs, retrieval and agentic workflows in production-oriented environments.
• Confidence across MLOps, LLMOps, technical assurance, monitoring and recovery patterns.
• A strong grounding in fairness, explainability, AI controls and responsible release decisions.
• The ability to influence business and technical leaders while remaining close to the detail.
• Experience in business lending and wealth, credit risk or pricing decision science is highly regarded, not essential.

What your success will look like … 

• Customers and bankers receive reliable, fair AI-supported experiences. 
• Models and agents perform against clear quality and task-success measures. 
• Squads reuse strong patterns, reduce technical rework and make better release decisions. 
• Craft leadership deepens, peer review improves and technical capability becomes less dependent on a small number of individuals.
