This position supports NASA's lunar transportation initiatives through independent engineering assessments of spacecraft, payloads, launch vehicles, and integrated transportation systems. Responsibilities include evaluating structural loads, dynamic environments, analytical models, hardware test results, model correlation, and verification evidence to determine flight readiness. Candidates must bring extensive aerospace structural analysis experience and practical flight hardware testing expertise. The position may be filled at the Senior Engineer or Subject Matter Expert (SME) level based on experience and technical qualifications.

• Manipulate mass and stiffness matrices and develop reduced-order dynamic models using Component Mode Synthesis, Craig-Bampton reduction, and related analytical techniques.
\n
• Support and independently assess flight hardware structural and environmental testing, including modal surveys, vibration, acoustic, shock, and other dynamic qualification tests.
\n
• Review test requirements, plans, procedures, instrumentation, input environments, response limits, acceptance criteria, and technical reports to evaluate hardware qualification and flight readiness.
\n
• Perform pre-test analytical predictions, post-test data evaluations, and structural model correlation using measured flight hardware or flight-like hardware responses.
\n
• Investigate test anomalies, exceedances, unexpected structural responses, and verification discrepancies; assess root causes, hardware impacts, corrective actions, retest requirements, and flight rationale.
\n
• Identify bounding test environments, critical modes, sensitive interfaces, off-nominal conditions, and potential failure modes to improve analytical and verification coverage.
\n
• Develop and review structural test plans, qualification and acceptance criteria, engineering procedures, verification documentation, and technical reports.
\n
• Participate in NASA technical reviews, design reviews, test readiness reviews, test activities, and engineering assessments with spacecraft providers, launch vehicle providers, and contractors.
