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.
Generate high quality grids and apply Computational Fluid Dynamics (CFD) to simulate and analyze the performance and operability of complex high-speed air-breathing propulsive flowpaths and vehicles. Verify solution accuracy.
Post process CFD solutions to evaluate performance metrics, to evaluate flowpath operability, to estimate flight performance, and to build aero-propulsive databases. Develop and applie software to pre- and post-process grids and solutions.
Prepare technical reports, research papers, and presentations to communicate simulation results in a clear and concise manner.
Investigate the fundamental physics associated with air-breathing propulsive flowpaths and test facilities and use CFD to design and evaluate new flowpaths and test facility hardware. Use CFD to assist with interpreting ground test data.
Apply design of experiments/response surface methods to model aero-propulsive databases. Use these methods to understand performance sensitivities, to quantify uncertainties associated with a solution, and to optimize some aspect of the design.
Serve as a technical monitor on grants, cooperative agreements, contracts, Small Business Innovation Research (SBIRs) and other contractual mechanisms with university and industry partners.
Work with a team of researchers and collaborate with team members and others to solve challenging problems.
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.
