We are hiring a Senior Loads & Dynamics Engineer at Kennedy Space Center, FL, to support NASA's Transportation Engineering Support (TENS) effort and Moon Base Transportation (MBT) Office. This role focuses on spacecraft and launch vehicle structural dynamics, coupled loads analysis, finite element analysis (FEA), modal analysis, vibration and acoustic testing, mechanical shock, and flight hardware qualification using NASTRAN, FEMAP, MATLAB, Python, and related engineering tools.

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.

Responsibilities

• Perform independent technical assessments of spacecraft, payload, launch vehicle, and integrated transportation system loads and structural dynamics, including analytical methods, assumptions, models, margins, and engineering conclusions.
• Conduct and evaluate coupled loads analysis (CLA), finite element analysis (FEA), modal analysis, and structural dynamics assessments for aerospace flight hardware.
• Develop and review finite element models, evaluating mass properties, stiffness, damping, boundary conditions, load paths, interfaces, model fidelity, and sensitivities.
• 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.
• Manipulate mass and stiffness matrices and develop reduced-order dynamic models using Component Mode Synthesis, Craig-Bampton reduction, and related analytical techniques.
• Support and independently assess flight hardware structural and environmental testing, including modal surveys, vibration, acoustic, shock, and other dynamic qualification tests.
• 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.
