Department Overview

The Data Science & Decision Science Department is both a “Delivery” team that is a sophisticated practitioner of data science and a “Center of Excellence” team that supports other practitioners in an enterprise-wide Hub & Spoke analytics adoption model.

As a Delivery team, this Department uses industry leading data science and change management practices to drive PG&E’s transition to the sustainable grid of the future. The Department works cross-functionally across the company to enable data driven decisions applying analytics, as well as improvements to relevant business processes. Deployed to some of PG&E’s highest priority arenas, the Department does not specialize in a traditional utility domain, such as asset management or program administration, but instead specializes in extracting useful insights from disparate data sets and facilitating actions informed by these insights.

As a Center of Excellence team, this Department listens to the needs of practitioners across the company, along with emerging industry practices, and builds standards, processes, tools, knowledge and best practices that meet the current and future needs of the enterprise.

This team works on a wide variety of difficult problems, offering great variety in the work, and constant opportunity to explore and learn. Current and past engagements include:

  • Creating wildfire risk models that are used by regulators and the utility to prioritize asset management
  • Developing computer vision models that improve, accelerate, and automate asset inspections processes
  • Predicting electric distribution equipment failure before it occurs, allowing for proactive maintenance
  • Forming the analytical framework behind PG&E’s Transmission Public Safety Power Shutoff
  • Optimizing non-wires alternative resource portfolios, like the Oakland Clean Energy Initiative, including location and resource adequacy considerations
  • Analyzing customer demographic, program participation, and SmartMeter interval data to build program targeted propensity models, e.g. for customer owned distributed energy resource technologies
  • Identifying and investigating anomalous customer natural gas usage, in order to resolve dangerous customer side leaks


As the first Principal Machine Learning Engineer (MLE) at PG&E, you will build our model deployment and continuous improvement practice. You will architect, build, and maintain the foundation and standard technologies for machine learning models/ algorithm serving, monitoring and maintenance for the company.  You will work with senior leadership to set deployment standards as well as replicable, reliable and scalable technologies for the IT department and the Data Science and Decision Products teams. While designing the initial machine learning infrastructure is an important contribution, you will also develop yourself the first iterations of that infrastructure hands on. You will also coach junior machine learning engineers, and collaborate with data engineers and data scientists in developing data and digital products. As your values, you care about our environment, climate change, clean energies, sustainable prosperity for Californians.  If developing a new machine learning infrastructure for artificial intelligence algorithms that empower the next generation energy systems excites you, this is your job.
