Title: Modeling & Simulation Engineer - NLR 2876A
Function: Engineering
Position Type: Regular, Full-Time
Pay Type: Exempt
Grade: 33-34
US Citizenship Required: Yes

This opportunity is being offered by National Aerospace Solutions, the team selected by the U.S. Air Force to conduct Test and Operations Sustainment at the Arnold Engineering Development Complex (AEDC), Arnold Air Force Base, Tennessee. National Aerospace Solutions is a limited liability company comprised of Bechtel National Inc. (as lead company) and Sierra Lobo Inc. with teaming Subcontractors nLogic Inc. and Chugach Federal Solutions Inc. AEDC operates more than 55 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges and other specialized units located in six states. Many of the complex's test units have capabilities unmatched elsewhere in the United States; some are unique in the world. AEDC is one of three installations which are part of the Air Force Test Center (AFTC), one of six subordinate commands of the Air Force Materiel Command organization and an important national resource.

AEDC's mission is to conduct developmental test and evaluation for the Nation through modeling, simulation, ground, and flight test. Execution of the mission requires a large team of highly qualified and dedicated professionals from multiple technical disciplines to effectively accomplish the objectives of our test customers.

Job Duties:
Working with a range of experienced Modeling and Simulation engineering personnel, the successful candidate will apply Computational Fluid Dynamics (CFD) tools to Arnold Engineering Development Complex (AEDC) relevant test facility issues, assess concepts, analyze expected performance, and troubleshoot problems with ground test infrastructure systems used in the execution of ground testing of air and space vehicles at AEDC.

• Support software development for computational modeling and simulation (M&S) tools.
• Support the development and application of computational models and simulations, coupled with high-performance computing, to solve complex physical problems arising in engineering analysis and design (computational engineering).
• Ensure that M&S tools being developed and used meet the needs for predicting performance of complex hardware systems and troubleshoot issues when tools are not capturing the systems accurately.
• Analyze and identify deficiencies in existing computational fluid dynamics (CFD) codes; formulate, implement, and validate improvements to overcome those deficiencies.
• Develop new computational approaches in the areas of fluid-thermal chemistry, turbulence, numerical algorithms, and code-processing.
• Support the expansion of CFD capabilities into the hypersonic regime by implementing and/or applying new algorithms and tools that account for combustion and high speed chemical reactions required to simulate hypersonic vehicles flow fields and high temperature facilities. Evaluate, select, and apply engineering computations, techniques, procedures and criteria, in making adaptations and modifications.
• Perform work involving the preparation, execution, interpretation and review of aerodynamic computations using CFD codes for analysis of aerodynamic facilities.
• Engage the Technology Innovations Branch / Analytical & Science personnel as required to push for technological advances, facility improvements, advanced diagnostics, and complex problem solutions.
• It is a condition of employment to wear company issued PPE (Personal Protective Equipment) in accordance with supervisory direction and company policy
• Perform other related duties as required.
  Basic Qualifications:
  • B.S. degree in mechanical or aerospace engineering from an accredited college or university plus a minimum of 2 -3 years of relevant experience or a M.S degree in mechanical or aerospace engineering from an accredited college or university.
  • Current U.S. Citizenship is required. Preferred Qualifications:
    • Demonstrated technical knowledge of computational engineering methods and application of computational fluid dynamics (CFD) tools to hypersonic engineering problems with emphasis on modeling compressible, chemically-reacting flows in the subsonic, supersonic, and hypersonic flow regimes
    • Detailed knowledge of thermodynamics, combustion, and multidisciplinary modeling
    • A combination of code "development" and "applications" skills
    • Ability to work in a team developing/applying complex CFD models
    • Strong oral and written communication skills
    • Participates in and fosters a work environment that is based upon openness, trust, communication, teamwork, empowerment, innovation, and satisfaction
      Due to Air Force Security requirements, U.S. Citizenship is required for employment at AEDC.
