Job Description

Job Summary:

The National Laboratory of the Rockies (NLR) seeks a Postdoctoral Researcher to advance open-source modeling of critical mineral and material (CMM) flows within broader system contexts. The role involves collaboration across teams specializing in data automation, scaling and integration, life cycle and techno-economic analysis, economic modeling, material flow analysis, energy systems, and integrated assessment modeling.

Candidates should hold a recent PhD in Environmental Science, Environmental Engineering, Industrial Ecology, Chemical Engineering, Economics, or a related field. The ideal candidate is a self-motivated, highly proficient python programmer with strong optimization skills who can work independently. Additional experience in industrial datasets, process or systems modeling, and advanced opensource tools, as well as familiarity with NLR’s public databases is a plus. While this position is within the Strategic Energy Analysis Center (SEAC), candidates are expected to collaborate across NLR to support complex, interdisciplinary decision-making.

Job Description:

The candidate will join NLR’s integrated and systems modeling team to help develop next generation, AI-enabled, opensource models assessing U.S. CMM supply chain and manufacturing futures. Key responsibilities include building and integrating novel modeling platforms, developing datasets, and supporting regional and national decision support frameworks using industry standard practices in coding and data management. The candidate will also contribute to publications and collaborate with senior engineers and analysts.

Specific duties include:

• Advance and expand existing and build new modeling capabilities in industrial CMM analysis.
• Support the assessment of CMM futures using NLR datasets and tools such as LiAISON, ReEDS, and FINITO.
• Build expertise and gain proficiency in using and applying the Global Change Analysis Model (GCAM) in conjunction with NLR datasets and tools for systems analysis.
• Update, curate, and analyze industrial and life cycle data to build high‑quality unit datasets.
• Develop, write, and document code to support model development and code‑based assessment frameworks.
• Integrate cross‑cutting costing, life‑cycle, and process data.
• Apply quantitative and qualitative research methods to assess, validate, and visualize results.
• Write and publish research findings in peer-reviewed journals, conference proceedings, and technical reports.
• Present research findings to clients, scientific peers, and non-technical stakeholders.
• Collaborate with colleagues within and outside of NLR.

• Experience in optimization.
• Experience in advanced (hybrid, dynamic, consequential, and/or prospective) LCA tools and energy systems models.
• Experience with industrial datasets and process modeling, or developing custom life cycle inventories and in using established life cycle inventory databases.
• Familiarity with LCA software (experience applying Brightway and Brightway’s Activity Browser is particularly desired; experience in non-code-based LCA software such as GaBi, SimaPro, and OpenLCA is a plus).
• Strong analytical skills with a demonstrated ability to apply theoretical concepts to real-world scenarios.
• Self-motivated, quick learner with a proven ability to grasp new concepts and develop skills as needed.
