** Principal Applied Scientist - Enterprise AI
** through
** January 20, 2026
** at 11:59 p.m. (Central Time).Join Chevron’s Enterprise AI team to lead the design and delivery of industry specific foundation models and agentic AI systems that transform decision making and underpin the strategy for future growth for the company.  As a Principal Applied Scientist, you will architect and advance the AI foundation for Chevron’s proprietary data and workflows.

This role is ideal for senior scientists who blend deep domain expertise in energy with state-of-the-art ML/GenAI methods. You will also set technical direction, mentor multidisciplinary teams, and build reusable frameworks and analytical assets to accelerate Chevron’s AI ambitions at global scale.
*
* Key Responsibilities:

**
* ** Architect Industry Foundation Models
** Design domain tailored FMs for energy workflows (e.g., subsurface, production operations, supply & trading), leveraging new and emerging FM architectures and advanced methods such as instruction tuning, LoRA, adapter based fine tuning, prompt optimization, and RLHF/RLAIF.
* ** Fine Tune & Optimize Model Weights
** Own the end to end process for weight initialization, adaptation, quantization, distillation, and evaluation to meet accuracy, latency, and cost targets; establish best practices for versioning, reproducibility, and model cards.
* ** Develop & Operationalize AI Systems
** Build, test, and deploy production grade models and agentic workflows using Azure

ML, Azure OpenAI Service, and Databricks (Unity Catalog & Model Serving); maintain flexibility to integrate approved third party platform and/or model endpoints via Azure where appropriate, e.g. Data Robot
* ** Establish Reusable AI Frameworks
** Create modular, reusable components—feature stores, orchestration pipelines, evaluation harnesses, prompt/agent templates, and retrieval layers—that accelerate delivery across multiple AI applications.
* ** Technical Leadership & Mentorship
** Provide deep technical guidance to data scientists, AI engineers, and software engineers; lead design reviews, code reviews, and drive adoption of best practices for scalable AI.
* ** Collaborate Across Disciplines
** Partner with business stakeholders and cross functional engineering delivery teams to translate complex problems into measurable, scalable AI solutions, and to embed models into production systems and agentic workflows.
* ** Model Lifecycle & Responsible AI
** Work alongside Chevron’s Data & Insights Department to define standards for governance, monitoring, drift detection, retraining, and evaluation (offline/online); champion fairness, transparency, safety, and auditability across the model lifecycle.
* ** Innovation & Thought Leadership
** Lead research and experiments on foundation models, multimodal learning, retrieval augmented generation, and reinforcement learning; publish findings internally and externally where appropriate.

* Required Qualifications:

*** Advanced degree (MS or PhD) in computer science, statistics, mathematics, neurosciences, machine learning, engineering or related quantitative field
* 10+ years building and deploying enterprise-scale AI/ML systems, including technical leadership of complex initiatives
* Demonstrated expertise in foundation models and open-source LLM/SLM ecosystems, including fine-tuning, weight management, and evaluation.
* Strong proficiency in Python and modern ML frameworks (PyTorch, Tensor Flow, Hugging Face).
* Hands-on experience with Azure

ML, Azure OpenAI Service, and Databricks.
* Deep domain understanding of energy workflows (upstream, downstream, or supply & trading) and the ability to encode domain insights into model design
* Excellent communication, cross-functional collaboration, and the ability to set technical strategy and mentor teams.
