Job description

Duties

Duties described below are at the highest grade advertised. Duties assigned at lower grade levels will be of more limited scope, performed with less independence and limited complexity; duties will be commensurate with the grade of selected employee.
Apply CFD and numerical tools to simulate and analyze the performance and operability of high-speed air-breathing propulsive components, estimate numerical uncertainties, and apply optimization methods to improve performance.
Conduct research to understand the fundamental physics associated with air-breathing propulsive components, flowpaths and ground test facilities and use CFD to design and evaluate new components, flowpaths and test facility hardware.
Use programming skills to add new models and new capabilities into CFD and utility codes. These codes will be used in a parallel processing environment and new features may require extensive changes to the code to implement.
Develop new algorithms, methods, and solution approaches to reduce the time it takes CFD practitioner to go from an initial concept to a final solution.
Implement, verify and validate CFD software utilizing unit testing, benchmark cases, analytical solutions, and/or method of manufactured solutions to ensure accurate simulation results.
Utilize industry standard software tools (build systems, continuous integration, version control, and performance profiling) to aid in the development of CFD simulation tools for high performance computing (HPC) environments.
Serve as a technical monitor on grants, cooperative agreements, contracts, Small Business Innovation Research (SBIRs) and other contractual mechanisms with university and industry partners.
Prepare technical reports, research papers, and presentations to communicate simulation results in a clear and concise manner.
Foster a culture of engagement, diversity, inclusiveness, excellence and innovation. Champion NASA's commitment to Diversity, Equity, Inclusion and Accessibility to create an environment that promotes a commitment to safety, integrity, and teamwork.
