Description

The Applied Scientist will develop and improve time series forecasting models for Amazon Devices, with a specific focus on addressing the cold-start 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 non-existent, 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 cold-start 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 pre-launch data and proxy information to forecast seasonal trends and price-sensitive 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 cold-start scenarios, create visualizations to illustrate forecast uncertainty, and present findings to cross-functional 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.

Basic Qualifications

- 3+ years of building models for business application experience

- PhD, or Master's degree and 4+ years of CS, CE, ML or related field experience

- Experience programming in Java, C++, Python or related language

- Experience in any of the following areas: algorithms and data structures, parsing, numerical optimization, data mining, parallel and distributed computing, high-performance computing

Preferred Qualifications

- Experience using Unix/Linux

- Experience in professional software development
