Job description

Job Category: Accounting / Finance

Job Level: Individual Contributor

Business Unit: Customer & Corporate Affairs

Work Type: Hybrid

Job Location: Oakland

Department Overview

The Rates department within PG&E’s Customer & Corporate Affairs organization develops and provides expertise on gas and electric customer rates in regulatory proceedings at the California Public Utilities Commission (CPUC) and the Federal Energy Regulatory Commission (FERC).

With a primary focus on ensuring fair, equitable, and stable rates for our customers, the Rates department designs rate plans, conducts cost of service analyses, forecasts revenues, and analyzes trends and drivers impacting customer rates and bills. We support other organizations in understanding energy usage to enhance various programs and policies that support our customers.

Position Summary

PG&E is seeking a Data Scientist to support cost analyses used in PG&E’s electric and gas rate design proposals in regulatory proceedings. Data Science is foundational for ensuring that our customers’ rates are designed fairly and equitably. Data Scientist in Cost-of-Service team works cross-functionally to design, develop, and execute scripts, programs, models, algorithms, and processes, using structured and unstructured data from disparate sources and sizes, generating defensible, valid, scalable, reproducible and documented machine learning and artificial intelligence models (predictive or optimization) for problem solving and strategy development. Additionally, the data scientist educates the non-technical community on advantages, risks, and maturity levels of data science solutions and participates in internal and external communities of practice in data science/artificial intelligence/machine learning to advance knowledge in the field.

Data Scientist supports evidentiary hearings including assisting expert witnesses on developing or revising proposals, summarizing and evaluating others’ proposals, and responding to external requests. Utility business knowledge, an understanding of economic and financial concepts, and quantitative modeling such as programming, statistics and mathematics are key skills to be successful in this role.

The successful candidate will embody a balance of data science expertise, intellectual curiosity, structured thinking, written and verbal communication skills, and team‑orientation.

This position is hybrid, working from your remote office and Oakland General Office once per week and based on business needs.

PG&E is providing the salary range that the company in good faith believes it might pay for this position at the time of the job posting. This compensation range is specific to the locality of the job. The actual salary paid to an individual will be based on multiple factors, including, but not limited to, specific skills, education, licenses or certifications, experience, market value, geographic location, and internal equity.

This job is also eligible to participate in PG&E’s discretionary incentive compensation programs.

A reasonable salary range is:

Bay Area Minimum: $ 102,000

Bay Area Maximum: $ 162,000
