Working at NLR

NLR is located at the foothills of the Rocky Mountains in Golden, Colorado is the nation's primary laboratory for energy systems research and development.

Join the National Laboratory of the Rockies (NLR), where world-class scientists, engineers, and experts are accelerating energy innovation through breakthrough research and systems integration. From our mission to our collaborative culture, NLR stands out in the research community for its commitment to an affordable and secure energy future. Spanning foundational science to applied systems engineering and analysis, we focus on solving complex challenges to deliver advanced, secure, reliable, and cost-effective energy solutions.

Our work helps strengthen U.S. industries, support job creation, and promote national economic growth.

At NLR, you'll find a mission-driven environment supported by state-of-the-art facilities, multidisciplinary research teams, and strong collaborations with industry, academia, and other national laboratories. We offer robust professional development opportunities, and a competitive benefits package designed to support your career and well-being.

Job Description

Seeking full- or part-time graduate or highly qualified undergraduate candidates to join the NLR Center for Integrated Mobility Sciences. We are looking for candidates passionate about software development, code optimization, and reproducible science to engineer the next generation of modeling tools. You will work alongside domain researchers to professionalize codebases, build scalable data pipelines, and develop robust frameworks that quantify the implications of emerging transportation technologies.

Key Responsibilities

* Engineer Research Software:
Collaborate with researchers to translate complex transportation energy concepts into robust, modular, and maintainable software libraries; focus on refactoring legacy scripts into production-grade tools.

* Build Scalable Data Pipelines:
Architect and implement high-performance computing (HPC) workflows to ingest, clean, and process large-scale geospatial and mobility datasets efficiently.

* Optimize Existing Tools:
Enhance the performance and reliability of existing tools and models; implement parallelization strategies, improve memory management, and ensure code scalability.

* Ensure Software Quality:
Champion software engineering best practices within the research team, including implementing unit/integration testing, setting up CI/CD pipelines, and managing version control (Git) workflows.

* Documentation & Dissemination: create comprehensive technical documentation (e.g., Sphinx, Read The Docs ) for developed tools; assist in the technical writing for peer-reviewed publications regarding model architecture and computational methods.
