Department Overview

The Enterprise AI Center of Excellence (AI CoE) is PG&E’s enterprise capability for accelerating safe, responsible, and value-driven AI adoption. The AI CoE guides the organization through AI Advisory, AI Governance, and AI Factory capabilities—helping business teams identify high-value opportunities, navigate responsible AI requirements, and build, deploy, and scale AI solutions into production. The team plays a central role in PG&E’s AI transformation by establishing reusable delivery patterns, advancing enterprise AI standards, and enabling AI solutions that improve affordability, safety, reliability, operational efficiency, and coworker productivity.

Position Summary

We are seeking a Principal Data Scientist (AI Engineer focused) to serve as the chief technical staff member within Enterprise AI CoE. You will be the senior-most hands-on technical leader for enterprise AI execution, responsible for setting technical direction, designing scalable AI and agentic AI architectures, and guiding complex AI solutions from concept through production adoption. You will help lead significant changes in how PG&E adopts, governs, builds, and scales AI by establishing practical engineering standards, reusable solution patterns, and trusted technical approaches for generative AI, agentic systems, machine learning, and enterprise data science.

This is a highly visible technical leadership role requiring deep expertise in Python-based AI engineering, cloud AI platforms such as AWS Bedrock, agentic AI frameworks, retrieval-augmented generation, AI evaluation, observability, responsible AI, and production-grade MLOps/LLMOps. The successful candidate will work closely with Enterprise AI leadership, AI Cloud Engineering, Enterprise Architecture, Cybersecurity, Legal, Privacy, product teams, business sponsors, and line-of-business SMEs to ensure PG&E builds AI solutions that are technically sound, operationally scalable, secure, compliant, and tied to measurable business value.

This position is hybrid, working from your remote office and in-person at our Oakland Headquarters 1-2x per week or based on business needs or company requirements.

Job Responsibilities

• Serve as the chief technical staff member for the Enterprise AI CoE, providing hands-on technical leadership across AI Advisory, AI Governance, and AI Factory priorities.
• Set the technical vision and architecture direction for enterprise AI execution, including generative AI, agentic AI, traditional machine learning, AI-enabled automation, and reusable AI solution patterns.
• Lead the design and implementation of production-grade AI systems using Python, AWS Bedrock, enterprise LLM gateways, agent orchestration frameworks, retrieval-augmented generation, vector search, APIs, and secure enterprise integrations.
• Establish reusable technical standards, reference architectures, design patterns, prompt and agent templates, evaluation harnesses, and engineering best practices that enable AI solutions to scale across PG&E.
• Act as the senior technical reviewer for complex AI use cases, model designs, agent workflows, AI architecture proposals, and production readiness decisions.
• Guide AI Factory execution by helping teams move from prototypes and pilots to reliable, monitored, governed, and supportable production AI solutions.
• Partner with business sponsors, product owners, data scientists, engineers, platform teams, and SMEs to translate high-value business needs into technically feasible and measurable AI solutions.
• Drive development of agentic AI capabilities, including task-based agents, single-domain agents, multi-agent workflows, tool use, memory, orchestration, human-in-the-loop controls, and enterprise system integration.
• Define and apply AI quality practices, including model and agent evaluation, regression testing, red teaming, responsible AI review, observability, performance monitoring, cost tracking, and lifecycle management.
• Mentor and coach data scientists, AI engineers, product teams, and business-facing practitioners to raise the technical maturity of AI delivery across PG&E.
• Represent the Enterprise AI CoE’s technical perspective in cross-functional forums with AI Cloud Engineering, Enterprise Architecture, Cybersecurity, Legal, Privacy, Governance, and line-of-business leadership.
• Stay current on emerging AI technologies and translate external trends into practical, governed, enterprise-ready recommendations for PG&E.
