The Opportunity

Westpac is building the next chapter of AI capabilities across Consumer Mortgages, and this newly created role leads it.

As Executive Manager AI Science, Mortgages, reporting to the Head of AI, you will own the Mortgages AI strategy, target state and roadmap, and translate customer, lending and operational priorities into measurable outcomes aligned with divisional and enterprise AI direction.

This is a hands‑on leadership role. Your credibility will come from deep, recent data and AI science practice in complex, highly regulated financial services. You will review modelling choices, sharpen experiments, guide agent and solution design, and help teams move from a well‑framed problem to safe, reliable production adoption.

You will also build capability for the future: recruiting and growing a high‑performing team, coaching technical leaders and creating an environment where different perspectives improve decisions and customer outcomes.

Key Responsibilities

• Own and maintain the Mortgages AI strategy and roadmap with product leaders, aligned to divisional and enterprise AI strategies, priorities and approved capability direction.
• Partner with product leaders to frame and prioritise use cases with clear customer problems, users, benefits, success measures, data needs, delivery ownership and risk classification.
• Provide technical direction across predictive AI, optimisation, document intelligence, generative AI and agentic systems.
• Be accountable for solution quality from problem definition and experimentation through validation, implementation, monitoring and retirement.
• Ensure every use case meets Group AI risk policies and guidelines, embedding privacy, security, model risk, Responsible AI, explainability, fairness, human oversight and operational resilience from the outset.
• Connect portfolio priorities with enterprise AI, data, technology and operating capabilities, agreeing interfaces, acceptance criteria, implementation plans and accountable owners.
• Monitor delivery, adoption, model performance, control effectiveness and realised value, intervening or escalating where outcomes, controls or timelines are at risk.
• Build reusable patterns and grow the broader AI Science practice through shared standards, technical review, coaching and knowledge sharing.

Key Ingredients for Success

• 10+ years in data science and applied AI, including senior leadership, with recent hands‑on practice in banking, lending, insurance or another complex, highly regulated financial services domain.
• Deep capability in predictive modelling, experimentation, optimisation and model validation.
• A track record of taking advanced analytics or AI solutions into controlled production use, with sound knowledge of MLOps or LLMOps and end‑to‑end lifecycle management.
• Practical understanding of LLMs, document intelligence and agent workflows, paired with disciplined judgement on where they should and should not be used.
• People leadership experience including building or scaling technical teams, hiring capability, coaching senior practitioners and setting clear technical direction.
• Executive influence and communication skills: you can make complex technical, customer and risk trade‑offs understandable and actionable while staying credible with data scientists, engineers, product, operations and risk partners.
• A sound risk mindset and a demonstrated commitment to fair, explainable and well‑controlled customer outcomes.
• Exposure to mortgages, credit or lending decision science, including document‑heavy or servicing workflows.
• Experience contributing reusable models, agent patterns or evaluation approaches across a wider practice or community.

You will shape an important AI portfolio, build capability from the ground up and contribute reusable models, agent patterns, evaluations and delivery lessons across the broader AI Science community.

Importantly, your work will help deliver customer and lending outcomes that are useful, fair, explainable and built to last.
