Job Title: Computational Scientist

Description
The Leidos Research Support Team supporting the National Energy Technology Laboratory (NETL) is seeking a Computational Scientist to join our team in Pittsburgh, PA. This opportunity will allow side by side execution of research with world-class scientists and engineers using state of the art equipment to contribute to new areas of basic and applied research. The work will support the development of advanced physics-based models for understanding mechanical, structural, and fluid dynamics in natural gas infrastructure. A core focus of this role is to integrate Computational Fluid Dynamics (CFD) and fluid-structure interaction (FSI) into gas pipeline modeling, as well as to accelerate the training of AI and ML models. The successful candidate will collaborate with an interdisciplinary team to create Multiphysics-based models that will be validated through experimental and field tests, including real-world data collection from natural gas pipelines.

The researcher will also apply advanced data analytics methods to classify spatial, temporal, and frequency-dependent features of optical fiber-based distributed sensing data. These models and data will be used to predict incipient failures, leveraging distributed optical fiber sensing, wireless sensor technologies, and other infrastructure monitoring tools, including subsurface systems. In this position, the researcher will have opportunities to publish in high-quality peer-reviewed journals, present at national and international conferences, and contribute to the development of new intellectual property. Regular project reporting will be required. Given the extensive interface with clients and collaborators, strong communication skills are essential.
