Position Type: Regular, Full-Time                                  
Pay Type: Exempt                           
Grade: 34/35
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.  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.
 
Exciting career opportunities exist for experienced / mid-career Mechanical Engineers in roles within Design Engineering.
 
Job Duties:
Mechanical Design Engineers design, evaluate, analyze, and assist in the fabrication and installation of hardware across the complex, including process piping systems, drive systems, mechanisms, and test hardware.  Mechanical design engineers work closely with test and system engineers in development of design requirements and ensuring proposed designs meet those requirements.  Close coordination with manufacturing is required to ensure economic and feasible designs.
 
Typical assignments for each position may include:
  • Independently perform moderately complex to complex analysis and design of components, systems, and facilities.
  • Performs complex analysis and design of components, systems under the direction of a more Senior Engineer.
  • Check simple to moderately complex analysis and design originated by less experienced engineers.
  • Develop concepts for new piping systems and provide flow, flexibility, thermal, structural, or any other required analysis to support the proposed design.Evaluate the analysis results for suitability relative to applicable codes and standards.
  • Develop concepts for new hardware and provide thermal, structural, flow, structural/stress analysis, possibly including vibration analysis, or any other required analysis to support the proposed design.Evaluate the analysis results for suitability relative to applicable codes and standards.
  • Structural design and analysis of pipe supports, platforms, and other structural support members.
  • Fatigue analysis of metal and composite materials for facilities, test systems, and process systems.
  • Designing mechanisms, wind tunnel models, and test fixtures including associated stress analysis.
  • Designing test hardware including stress analysis of complex or unique geometries such as blades or flexures or thermal-structural stress analysis at extreme thermal conditions.
  • Provide engineering support to the appropriate craft workforce to facilitate maintenance and repair of existing systems.Evaluate existing hardware for safety, security and potential for improvement.
  • Work with the design team (drafters, checkers, etc.) to produce complete design packages, including detailed drawings, analysis reports, and equipment specifications, and be capable of communicating the details of these design packages to the remaining project team (system engineers, test engineers, project managers, craft supervisors, etc.)
  • Coordinate with the appropriate system engineer, craft supervisor, and/or work planner to ensure that hardware is fabricated and installed in accordance with the approved design package.
  • May serve as Team Lead for small teams conducting simple to moderately complex analysis and design of components, systems, and facilities.
  • May serve as responsible engineer/point of contact for the Design Engineering support to a simple, short-duration project.
  • Provides coaching and guidance to entry-level and early-career members of the team.
  • 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.
