Data Scientist - AI & Analytics (DataX)

• Sydney Location / Hybrid Working 
• Make an impact where data meets insight

At Westpac, we’re reimagining how economic insight is created, scaled, and delivered. This is not a traditional data science role. You’ll sit at the intersection of AI, data engineering, and macroeconomics—building the next generation of data-driven research that shapes one of Australia’s most trusted market voices.

The DataX and Economics teams sit within WIB DDAI (Data, Digital & AI) and deliver data-driven products and insights to external institutional clients, while Economics provides macroeconomic research and forecasts that shapes Westpac's market voice. 

If you’re a highly experienced Data Science SME who is a hands-on builder and thrives on translating complex ideas into real-world, production-grade solutions—this is your platform to shine! 

Working within the DataX + Economics partnership, you’ll leverage shared data assets, modern tooling, and scalable platforms to deliver high-impact outcomes for institutional clients and internal research.

• Build and deploy econometric + machine learning (ML) models for forecasting, nowcasting, and scenario analysis
• Develop AI-enabled tools (NLP, automation, insight generation) to transform research workflows into production
• Translate economic hypotheses into robust quantitative frameworks
• Work hands-on with macro, transaction, and alternative datasets to unlock insights at scale
• Drive end-to-end model lifecycle—from experimentation to production, validation, and governance
• Present insights to both technical and executive audiences

• Tertiary qualifications in Computer Science
• Proven experience delivering production-grade data science / ML solutions (not just POCs or academic work)
• Strong background in statistical modelling and time-series analysis
• Deep capability in Python (scikit-learn, statsmodels, PyTorch/TensorFlow)
• Deep track record building scalable models and data-driven products
• Ability to operate in complex enterprise environments with strong stakeholder engagement
• Economics, econometrics, or financial markets exposure
• Experience building NLP / LLM-driven solutions, complemented by solid Cloud ML platforms (Azure ML, SageMaker or similar)
• Experience working alongside research, strategy, or domain experts
• You’re curious, commercial, and delivery-focused and you get energy from turning ambiguity into structured, scalable solutions
• You’re a hands-on problem solver who ships—not just experiments and you communicate complex ideas with clarity and influence
