Data Systems AI/ML Engineer

Posted 6 days ago Oak Ridge National Laboratory Data Systems AI/ML Engineer 9 Day Fortnight Remote · USA The 4-day week in United States About the role Requisition Id 17411 Overview: The Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL) is seeking a Data Systems AI/ML Engineer for its Earth Sciences Informatics portfolio. In this role, you will develop AI-driven methods that make data from the Atmospheric Radiation Measurement (ARM) user facility easier to find and use. You will build training datasets from years of ARM metadata records and design and implement conversational interfaces powered by large language models (LLMs) that help researchers discover data intuitively and efficiently. You will work as part of a collaborative team and pursue independent research and development. The ARM Data Center processes, archives, and distributes atmospheric observations from observatories around the globe, and provides computing infrastructure and analysis tools to the scientific community. Your work will directly improve how that community accesses and uses these data. Major Duties and Responsibilities: Research, develop, and deploy AI/ML methods, including LLM-based conversational interfaces and retrieval systems, that improve discovery and usability of ARM data. Build and maintain training and evaluation datasets derived from ARM metadata records. Work with data scientists, database engineers, software engineers, and DevOps engineers to take systems from prototype to production. Support researchers and developers in creating tools for the ARM Data Center. Grow into a leadership role in AI/ML engineering for the group, demonstrated through deliverables to sponsors, platform development, technical presentations and demonstrations, and, where appropriate, inventions, patents, or copyrights. Identify and pursue opportunities to expand existing AI/ML workflows and start new ones. Publish and present at workshops and conferences, and help build collaborations across the ARM community. Follow and promote good practice in research integrity, AI/ML and software engineering, and safe and secure work in compliance with ORNL policies, standards, and procedures. Basic Qualifications: A BS degree with at least 2 years of relevant experience, or an MS degree with at least 1 year of relevant experience, in computer science, data science, machine learning, artificial intelligence, environmental informatics, or a closely related field. Two years of Python programming experience, including data processing, scripting, or ML workflows. Academic, research, and internship experience counts. Working knowledge of core ML concepts, such as supervised and unsupervised learning, embeddings, and model evaluation. Familiarity with structured data, metadata, or information retrieval concepts. Interest in applying AI/ML to real-world scientific or environmental data problems. Strong written and verbal communication skills and the ability to work in collaborative, research-oriented environments. Preferred Qualifications: You are not expected to have all of these. Depth in a few areas is more valuable than shallow coverage of all of them. LLMs and retrieval Experience with natural language processing (NLP) or LLMs, through work or coursework. Retrieval-augmented generation (RAG), agentic RAG, or agent-based AI systems. Embeddings, semantic search, and prompt development. Orchestration frameworks such as LangChain or Agno. Familiarity with or interest in protocols for LLM tool integration and context exchange, such as the Model Context Protocol (MCP). Vector databases or search engines such as PGVector or Milvus, and knowledge of indexing, ranking, and similarity search. ML and evaluation Python scientific stack (NumPy, pandas, scikit-learn) and Jupyter notebooks for exploration and prototyping. PyTorch or TensorFlow, and libraries such as Hugging Face. Experience evaluating or benchmarking ML or LLM-based systems, including experiment tracking and monitoring tools such as MLflow or custom evaluation pipelines. Logging, tracing, and performance monitoring for AI systems. Backend and engineering RESTful API development with FastAPI, Flask, or similar frameworks, and experience integrating AI services into backend systems or data pipelines. Git and collaborative development workflows. Familiarity with Docker. Scientific data Experience with scientific datasets, metadata standards, or data catalogs. Knowledge of FAIR (Findable, Accessible, Interoperable, Reusable) data principles and reproducible research practices. Interest in atmospheric science or Earth system data.
