Argonne National Laboratory

Hours: Full time
Where: Lemont, IL USA
Posted: Sep 4

Argonne National Laboratory is seeking a research staff member in the area of model development, life cycle analysis (LCA), and technology assessment to quantify energy and environmental effects of energy systems and/or materials. This is a full-time position with the Life Cycle Analysis and Technology Assessment Department in the Energy Systems and Infrastructure Analysis Division. We are seeking applicants with a combination of engineering background and extensive knowledge and experience of Python programming language and large language models (LLMs) to expand and enhance the Argonne GREET LCA model, including building application programming interfaces (APIs), integrations using modular architecture, and interactions with user interfaces (UI).

What you'd do

Work closely with the GREET life cycle analysis research team to improve the software architecture design, data schema, calculation engine, database management, and expandability for the Python-based GREET software (PyGREET)
Apply the Python programing language and LLMs to develop, train, and deploy artificial intelligence capabilities in PyGREET
Build a rigorous and trustworthy data ingestion pipeline to collect, validate, and develop datasets for specific energy systems and/or material technology
Conduct rigorous LCA studies in the GREET modeling platform
Work with collaborators from other national labs and academia to evaluate complex systems and to incorporate new data in analyses
Communicate with DOE and other sponsors to address sponsors’ LCA needs and market the Department’s analytic capabilities for new programs.

What they want

Experience in LCA, process modeling, or closely related areas
Extensive experience in developing and deploying software using Python and LLMs
Extensive experience in interacting with sponsors and external collaborators
Experience in leading projects and tasks, tracking project progress, and directing junior staff
Expertise in topics related to process modeling and energy, resource, and environmental analysis of energy systems and/or materials and product systems
Excellent skills in written and oral communication to effectively interact with sponsors, collaborators, and internal team members
A successful candidate must have the ability to model Argonne’s Core Values: Impact, Safety, Respect, Integrity, and Teamwork.
This position requires onsite presence at Argonne National Laboratory in Lemont, Illinois.
