As a Research Aerospace Engineer, AST, Fluid Mechanics in the NASA Advanced Supercomputing Division (NAS) at Ames Research Center, you will leverage cutting-edge physics-based modeling methods to enhance capabilities within the computational fluid dynamics (CFD) solver framework developed in-house. You will lead efforts to predict next-generation flight vehicle characteristics using high-fidelity CFD methods to reduce program cost and ensure mission safety and success.

Duties

Develop an understanding of the physics of flow phenomena, and physical models of these phenomena to improve the methodology for calculating the flow of fluids through or about aircraft, launch vehicles, entry vehicles, etc., and their components. Conduct specialized studies on flight vehicles utilizing high-fidelity computational fluid dynamics (CFD) methods, which may include overall and individual major systems components, to ensure their safety, suitability and effectiveness in operation. Lead the development of adaptive mesh refinement (AMR) methods within a Cartesian-based CFD framework. Support development and testing of commercial supersonic aircraft concepts by analyzing both near-field and ground noise estimates using the Cart3D aerodynamic simulation package with output-based mesh adaptation. Perform 3D high fidelity asteroid entry simulations using Cart3D on High Performance Computing platforms as part of NASA’s Asteroid Threat Assessment project. Contribute to efficiency enhancements of computational tools and support development efforts targeting GPU-accelerated compute architectures. Document analysis results through technical reports and communicates findings with program stakeholders through publications and periodic briefings. 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.

Qualifications

In addition to the Basic Education Requirement (in the Education section below), to qualify for this position you must meet the requirements below. Specialized experience is experience that has equipped you with the particular ability, skill, and knowledge to successfully perform the duties of this position and is typically in or related to this line of work. NASA utilizes OPM-approved qualification and rating requirements specific for Aerospace Technology (AST) positions which recognizes NASA's unique aerospace work. The specific qualifications and minimum education requirements are further described below and within the education section of the job announcement. Vacant research positions may be filled at one of several grade levels depending upon the scientific impact of the person selected. A review may be required to determine the appropriate grade level of the position and supplemental materials may be required from the selectee. To qualify for GS-14, you must have one year of directly related specialized experience equivalent to the GS-13 level: Developing novel and implementing existing Cartesian-based computational fluid dynamics (CFD) modeling methods for the assessment of next-generation aircraft concepts; Performing software research and development to migrate existing aerodynamic CFD simulation codes to new and emerging distributed memory High Performance Computing platforms; Implementing adaptive mesh refinement methods within a CFD framework to enable scalable mesh adaptation on massively parallel computers. Your resume must include a clear and detailed narrative description, in your own words, of how you meet the required specialized experience. Experience statements copied from a position description, vacancy announcement or other reference material constitutes plagiarism and may result in disqualification and losing consideration for the job. NASA prohibits the use of artificial intelligence (AI) or AI-assisted tool in drafting application and assessment responses. Please visit https://www.nasa.gov/careers/how-to-apply/#Artificial-Intelligence to review NASA's guidance on the use of AI tools during the application process.

Education

Basic Education Requirement: You must have successfully completed a bachelor's degree with a major in one of the following:
a) Engineering from a college or university that has ABET accredited engineering programs
b) Physical Science, Mathematics, Life Science or other field of Science
c) Computer Science that included 30 semester hours or 45 quarter hours of course work in any combination of mathematics, statistics and computer science with at least half of those hours in mathematics and statistics courses that included differential and integral calculus; and that provided an in-depth knowledge of theoretical and practical applications of computer science, including digital computer system architecture and system software organization, the representation and transformation of information structures, and the theoretical models for such representations and transformations.

If you did not complete a qualifying bachelor's degree, you may be eligible if you have obtained a graduate degree in an AST qualifying field, as listed above.

Degrees in engineering technology are not considered qualifying for this position.

Engineering degrees earned within the United States: Engineering degrees earned within the United States must be from a college or university that has at least one ABET accredited engineering program. To find out if a school has at least one ABET accredited program, please visit http://www.abet.org.

Engineering degrees earned outside the United States: Engineering degrees earned outside the United States must be recognized by a Mutual Recognition Agreement (MRA), often known as accords. These are non-governmental agreements among organizations that accredit academic degree programs. MRAs recognize the substantial equivalence of mature accreditation systems and programs accredited by signatory organizations within their jurisdictions. For a listing of Signatories, please visit, https://www.abet.org/global-presence/mutual-recognition-agreements/is-your-program-recognized/.

Science and other related degrees earned within the United States: Science and other related degrees must have been awarded from colleges or universities that are accredited by recognized accrediting organizations. For a list of schools that meet this criteria, go to http://ope.ed.gov/accreditation/.

Science and other related degrees earned outside the United States: If you are using education completed in foreign colleges or universities to meet the qualification requirements, you must show that the education credentials have been evaluated by a private organization that specializes in interpretation of foreign education programs. These education credentials must be deemed equivalent to that gained in an accredited U.S. education program; or full credit has been given for the courses at a U.S. accredited college or university.
