Postdoctoral Researcher – Transportation Digital Twins and High-Performance Simulation
About The Position
The Advanced Computing Solutions Group in the Computational Science Center at the National Laboratory of the Rockies (NLR) seeks a postdoctoral researcher focused on transportation digital twins, large-scale simulation, and high-performance computing (HPC). The researcher will develop and validate traffic and vehicle simulation models and build scalable computing workflows to study connected and automated vehicle (CAV) operations, traffic control, and their mobility, safety, and energy impacts. The role involves independent research and collaboration with NLR scientists and external partners.
Requirements
- Must be a recent PhD graduate within the last three years.
- Must meet educational requirements prior to the employment start date.
- Ph.D. in a relevant engineering, computing, or mathematical discipline, subject to NLR postdoctoral eligibility requirements.
- Research experience in transportation modeling, large-scale simulation, or scientific computing.
- Proficiency in Python, C/C++, or MATLAB for modeling and data analysis.
- Ability to conduct independent research and collaborate in interdisciplinary teams.
Nice To Haves
- Experience with traffic or vehicle simulation tools such as SUMO or CARLA.
- Experience with parallel computing such as MPI or CUDA and HPC clusters.
- Background in CAV control, traffic signal operations, or traffic flow theory.
- Familiarity with V2X communication, transportation energy models, or co-simulation.
- Record of peer-reviewed publications and collaborative software practices.
Responsibilities
- Develop, calibrate, and validate traffic digital twin and co-simulation models.
- Design and evaluate vehicle and traffic signal control strategies using optimization or machine learning.
- Build and optimize scalable HPC workflows for large-scale simulation and scenario studies.
- Integrate traffic, vehicle, communication, and energy models into reproducible research tools.
- Analyze results and communicate findings through publications, reports, and presentations.
Benefits
- Medical, dental, and vision insurance.
- Short-term disability insurance.
- Pension benefits.
- 403(b) Employee Savings Plan with employer match.
- Life and accidental death and dismemberment (AD&D) insurance.
- Personal time off (PTO) and sick leave.
- Paid holidays.
- Potential eligibility for performance-, merit-, and achievement-based monetary awards.
- Some positions may be eligible for relocation expense reimbursement.
