Machine Learning Scientist

Website PepsiCo PepsiCo

PepsiCo’s Data Science and Analytics group is a team of data scientists, technology specialists, and business innovators who operate within eCommerce to build industry-leading systems and solutions. By focusing on machine learning and automation, the Data Science & Analytics group is pushing the bounds of possibility for PepsiCo and its strategic partners. We are currently hiring for either a senior position to augment our team or a leader to guide us.

What PepsiCo Data Science does:

  • Model ROI of marketing actions using with learning hierarchical latent representations of products and marketing actions. Currently this is released and helps the marketing team make marketing decisions. We need to replace the model with a deep graph network using the newly released DGL to better model interactions between entities based on their graphical relations in keyword, brand, and category spaces. We also need to replace the actions with an RL agent.
  • Supply Chain Forecasting for orders from ecommerce platforms. This is a supervised learning application that needs a model to estimate a probability distribution rather than mean. We have already released such a model but could always do better.
  • NLP to understand user reviews. Currently uses statistical techniques.
  • Large scale statistical insights generation using pandas (and grab our data using SQL).

How PepsiCo Data Science does it:

  • Script using Python
  • Stochastically optimize using Tensorflow and PyTorch
  • Compute on a team server with 4 Tesla V100s (Nvidia’s new model with TPU cores)
