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, ReadTheDocs) for developed tools; assist in the technical writing for peer-reviewed publications regarding model architecture and computational methods.
