Senior Staff Engineer, Mechanical Test (R4413)

Leads mechanical testing for aircraft hardware, designing test fixtures with hydraulics and sensors, automating data analysis with Python, and performing FEA on metallic/composite materials. Requires 12+ years experience, Mechanical Engineering degree, and NX proficiency.

About the job

What you'll do

  • Develop and execute test plans to validate mechanical performance, structural integrity, and environmental durability from start to finish.
  • Design, build, and operate test fixtures and systems involving hydraulic actuation, mechanical linkages, and sensor instrumentation.
  • Integrate and calibrate a range of sensors (e.g., load cells, pressure transducers, strain gauges, accelerometers) into test setups for accurate data collection.
  • Create and maintain python scripts to provide automation, signal processing, and result visualization.
  • Analyze test data, troubleshoot system behaviors, and generate detailed technical reports with design feedback.
  • Collaborate with cross-functional teams including mechanical design, systems, and electrical engineering to define test requirements, run test campaigns and deliver high quality results.
  • Lead CAD design of custom test equipment, prototypes, fixtures, and components, ensuring manufacturability and safety.
  • Perform Finite Element Analysis to simulate mechanical performance, validate design assumptions, and correlate analytical results with test data.
  • Work with metallic/composite materials in the design, fabrication, and testing of mechanical components, with consideration for their unique properties such as anisotropy, delamination risk, and layup configuration.
  • Support lab safety protocols, equipment maintenance, and continuous improvement of test capabilities.

Required qualifications

  • Bachelor’s or Master’s degree in Mechanical Engineering or related field.
  • 12+ years of experience in mechanical testing or product development environments.
  • Strong working knowledge of hydraulic systems and their control/measurement.
  • Experience with sensor selection, integration, and calibration in test environments.
  • Proficiency in Python for scripting, test automation, and data analysis.
  • Advanced CAD skills in Siemens NX with experience designing test hardware and prototypes.
  • Excellent problem-solving skills and the ability to work independently and in team settings.

Preferred qualifications

  • Hands-on experience performing MIL-STD testing (e.g., MIL-STD-810, MIL-STD-461) including vibration, shock, thermal, and EMI/EMC testing.
  • Subject Matter Expert in aerospace structures and dynamics test environments.
