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 The National Laboratory of the Rockies (NLR) is seeking to hire a postdoctoral candidate in mechanical engineering or a closely related field of study. The candidate will work with other engineers and scientists in the Thermal Energy Sciences Group within the Energy Conversion and Storage Center. The candidate will join a team of engineers and scientists studying thermal systems, including geothermal power, solar thermal power, and Underground Thermal Energy Storage (UTES).
Research will involve collaboration with other NLR centers, other national laboratories, universities, and industry.
This position requires advanced knowledge of simulation and optimization of engineered systems, with preference given to previous experience in the area of thermal systems such as geothermal, solar thermal, and thermal energy storage technologies. Research activities may include:
Developing technical and cost models of individual components, such as compressors, turbines, chillers, heat exchangers, liquid storage tanks, reservoir thermal energy storage, borehole thermal energy storage
Developing system models, such as power cycles, heat pumps, data center energy systems, combined heat and power systems
Developing methods to assess system value
Write technical reports, contribute to project review meeting, publish research results in peer-reviewed conferences and high-impact scientific journals.
The successful candidate will have completed coursework or have demonstrated experience related to heat transfer, thermodynamics, energy storage, computer programming, and thermal energy systems. Relevant experience can include thermodynamic power cycles, heat pumps or refrigeration, building energy modeling, or simulation of power systems.
Assumed responsibilities include close attention to documenting work in detailed technical records, maintaining clean and safe work conditions, conducting work with the highest professional standards, and presenting and publishing research in technical forums.
