• Analyze modal, transient, frequency response, sine vibration, random vibration, acoustic, and mechanical shock environments associated with launch and spaceflight operations.
• Evaluate quasi-static loads, inertial acceleration (g-loads), structural responses, and dynamic amplification affecting spacecraft, payloads, components, and interfaces.
• Assess acoustic loading environments and test results, including sound pressure levels (SPL), frequency-dependent acoustic spectra, and structural responses.
• Evaluate random vibration power spectral density (PSD), acceleration responses, test tolerances, notching strategies, response limits, and qualification or acceptance criteria.
• Analyze mechanical shock environments using shock response spectra (SRS), time-history data, hardware response measurements, and applicable verification requirements.
• Identify critical structural modes, load paths, dynamic sensitivities, interface loads, acceleration levels, and potential structural failure mechanisms.

• Review test requirements, plans, procedures, instrumentation, input environments, response limits, acceptance criteria, and technical reports to evaluate hardware qualification and flight readiness.
• Perform pre-test analytical predictions, post-test data evaluations, and structural model correlation using measured flight hardware or flight-like hardware responses.
• Investigate test anomalies, exceedances, unexpected structural responses, and verification discrepancies; assess root causes, hardware impacts, corrective actions, retest requirements, and flight rationale.
• Identify bounding test environments, critical modes, sensitive interfaces, off-nominal conditions, and potential failure modes to improve analytical and verification coverage.
• Develop and review structural test plans, qualification and acceptance criteria, engineering procedures, verification documentation, and technical reports.
• Participate in NASA technical reviews, design reviews, test readiness reviews, test activities, and engineering assessments with spacecraft providers, launch vehicle providers, and contractors.
• Coordinate with structures, mechanical systems, mechanisms, guidance, navigation and control (GN&C), propulsion, thermal, mission design, and systems engineering teams to evaluate integrated vehicle performance.
• Present technical findings, structural margins, test results, analytical sensitivities, qualification risks, and engineering recommendations to NASA and multidisciplinary program stakeholders.
• Use commercial and internally developed engineering analysis tools, including Python, MATLAB, C, C++, and related programming languages, to perform and automate structural dynamics analyses.
• Maintain configuration control, technical documentation, peer reviews, and traceability of analytical models, engineering assumptions, test data, and verification results.
• Travel as required to support engineering reviews, structural testing, and NASA program activities.
