The Applied Scientist will develop and improve time series forecasting models for Amazon Devices with a specific focus on addressing the coldstart problem for new unlaunched devices. They will implement and refine machine learning models that can accurately forecast demand patterns across different price points and seasonal periods for new Amazon devices helping optimize inventory and assortment decisions before product launch. This role offers an excellent opportunity to tackle complex forecasting challenges where historical data is limited or nonexistent requiring innovative solutions to capture potential demand signals seasonal trends and price elasticity for unreleased products. The scientist will analyze how pricing strategies and seasonal events impact consumer behavior and incorporate these insights into predictive models to better anticipate market demand.
Key job responsibilities Develop and implement forecasting models using Python focusing on techniques that address the coldstart problem for new Amazon Devices including transfer learning from similar products and incorporating external factors that may influence demand. Apply deep learning frameworks (TensorFlow/Keras PyTorch) to build sequence models (RNNs LSTMs) that can effectively utilize limited prelaunch data and proxy information to forecast seasonal trends and pricesensitive demand for new devices. Conduct sophisticated feature engineering tasks leveraging data from product attributes market trends and consumer preferences to create informative features for forecasting demand of unlaunched devices. Evaluate model performance using appropriate metrics for coldstart scenarios create visualizations to illustrate forecast uncertainty and present findings to crossfunctional teams to inform launch strategies and initial inventory decisions. Implement and continuously improve methodologies for incorporating early sales signals and rapidly adjusting forecasts as new Amazon Devices enter the market.
