Job Summary

We are looking for a Mechanical Engineer or Aerospace Engineer who wants to work in a multi-disciplinary team that plays a key role in supporting national defense. The engineer hired into this role acts as the โ€œquarterbackโ€ in one of the control rooms responsible for planning and execution of test plans for testing. This position does require shift work to support testing as test load demands.

Our Test Operations Engineers provide technical direction for safe and reliable operation of test equipment and integration of a customerโ€™s test article to an Arnold Engineering Development Complex test bed. This work involves practical application of engineering principles of mechanics, thermodynamics, heat transfer, hydraulics, pneumatics, and materials of construction. These principles are applied through the use of engineering tools including generating risk assessments, test plans, work instructions, and other engineering documentation in support of testing.

As part of a multi-disciplinary team, test operations engineers interface with other engineering teams across the complex including plant operations and systems, controls, instrumentation, design, facility data analysis, and modeling and simulation engineers as well as a cadre of skilled labor to ensure reliable operation and ability to meet future test needs.

 

Test Operations Engineers also provide system engineer capabilities as part of a team of mechanical and electrical engineers whose job it is to oversee installation, operation, sustainment, and troubleshooting of their assigned test cell equipment and systems. Some examples of test systems in various facilities include thrust determination and force measurement systems, fuel systems, icing systems, combustors, nozzles, water systems, gaseous nitrogen systems, hydraulic systems, lubrication oil systems, high pressure air systems, service air systems, liquid nitrogen systems, various sensors, etc. that are needed to reliably provide test data to our customers.

  • Ensure proper test / operations reporting (Ops Center, test resumes, Operating Test Logs, Test Unit Status Logs, Test Article Activity Logs, unplanned event reporting, etc.)
  • Perform facility characterization/ calibrations, monitor facility performance, and maintain system capability / performance maps and envelopes
  • Test operations engineers also operate as system engineers for equipment within or directly providing support to the test cell facility and may engage in some small design and analysis tasks as needed
  • Operate assigned test cell systems effectively
  • Work to develop the test operational requirements (test period directives, detailed run programs, etc.) ensuring test article mounts are structurally sound to withstand expected test
  • Direct test system checkouts and testing as required
  • Work with multidiscipline engineers, physicists, and skilled craft technicians in the test control room in operating the facility systems
  • Work extra hours and/or support off shift testing as required
  • Communicate clearly and utilize various methods of communication
