As an Aerospace Engineer with the Mechanical Engineering Branch, you will be responsible for thermal and fluid analysis of liquid, gas, and cryogenic liquid systems in the area of rocket propulsion testing. You will work on project teams to support government and commercial customers who are testing engines and engine components at Stennis Space Center. You will provide engineering solutions when problems arise and monitor corrective actions through completion.

Duties

Provides guidance on mechanical engineering design and fluid analysis work in the area of rocket propulsion testing. Analyzes cryogenic liquid, high pressure liquid and gas, pneumatic or hydraulic systems and provides recommendations for meeting customer requirements. Develops performance requirements and design criteria for evaluating propulsion test facilities including cryogenic and high-pressure propellant systems. Leads investigations to obtain baseline data for propulsion test system studies. Documents design process (i.e. design reviews) per procedures. Oversees fluid mechanical mathematical models of test facility pressurant, purge, and propellant systems in support of rocket propulsion test activities. Develops analytical and computational models of conventional fluid systems and high-pressure cryogenic propellant systems to evaluate and assess performance of the test facility. Identifies, investigates, and resolves standard problems in mechanical systems. Provides engineering solutions and technical consultation to civil servants and support contractors in the resolution and correction of field problems and monitors corrective actions through completion. Fosters a culture of engagement, diversity, inclusiveness, excellence and innovation. Champions 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 and have one year of specialized experience equivalent to the next lower grade, which has equipped you with the particular competencies needed to successfully perform the duties of the position described above. 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. To qualify for GS-13, you must have one year of directly related specialized experience equivalent to the GS-12 level: Performing thermal and fluid analysis of piping and tubing systems to determine flow characteristics of a system including changes in fluid pressure, temperature,and velocity through pipe/tube and pipe/tube components; Performing thermodynamic and heat transfer calculations to characterize heat and mass transfer in mechanical and/or energy systems; Analyzing test data to determine performance of fluid and/or energy systems. 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.
