Amazon’s operations in Australia is at a unique phase of rapid expansion. As our selection and local fulfilment network grows, the complexity of managing supply chain increases. To systemically address these complexities, we are establishing a team of subject matter experts by expanding Supply Chain Optimisation Technology (SCOT) team presence to Australia. We are looking for an exceptional Data Scientist to join this specialised team and help build the analytical foundations that allow us to automate and optimise our local supply chain at scale. Key job responsibilities - Build Predictive Models: Design, develop, and deploy machine learning models (e.g., time-series forecasting, regression, classification) to predict inbound volumes, leveraging signals from demand forecasts, vendor behaviour, and upstream planning systems unique to the Australian supply chain. - Drive Root-Cause Analysis: Apply statistical methods and causal inference techniques to quantify defect attributions across plan-over-plan changes, actuals-over-plan variances, and forecast accuracy degradation, translating complex analytical findings into actionable insights for stakeholders. - Enable Automated Intelligence: Leverage agentic workflows and LLM-based pipelines to build self-improving prediction systems for inbound volumes, automating feature engineering, model retraining, and anomaly detection to replace manual heuristics. - Advance Experimentation: Design and execute A/B tests and counterfactual analyses to measure the impact of supply chain interventions (e.g., buying policy changes, capacity adjustments) on inbound volume outcomes, providing rigorous evidence for decision-making. - Influence Strategy: Synthesise insights across product demand forecasting accuracy, inventory efficiency, and capacity planning to build data-driven narratives that influence inbound volume projections and supply chain strategy at the leadership level. About the team Have you ever ordered a product on Amazon and wondered how it got to you so fast? Wondered where it came from and how much it cost? If so, Amazon's Supply Chain Optimisation Technology (SCOT) organisation is for you. At SCOT, we solve deep technical problems and build innovative solutions in a fast-paced environment.

You will lead end-to-end systems spanning knowledge acquisition, retrieval, and reasoning. Specific responsibilities include: 1. Define the scientific roadmap for knowledge acquisition, representation, and retrieval at organizational scale. 2. Lead research on how AI systems should learn from experience — what to capture, how to generalize, when to forget. 3. Design evaluation frameworks for a system where "quality" means something new — right knowledge, right context, right confidence level. 4. Own end-to-end research from problem formulation through production impact measurement. 5. Mentor Applied Scientists and establish scientific standards for a new team. 6. Partner with engineering leadership to translate research into architecture decisions that shape the product. 7. Drive technical decisions on model architecture, training methodology, and evaluation frameworks, balancing scientific rigor with business impact. 8. Publish at top-tier venues and advance the state of the art in applied knowledge systems. A day in the life You will solve real-world problems by getting and analyzing large amounts of data, generate insights and opportunities, execute experiments, and develop statistical and ML models. The team is driven by business needs, which requires collaboration with other Scientists, Engineers, and Product Managers across the organization. You get to influence stakeholders with clear communication skills. You innovate on behalf of the customer and strategically build features. You will mentor junior members and help them grow. About the team Born out of Amazon's Personalization organization, which pioneered personalization at internet scale.
