Stress Analysis Senior Engineer

Stress Analysis Senior Engineer | Lockheed MartinThe Stress Analysis Engineer will own moderate-to-complex structural-analysis work-packages, mentor junior analysts, and provide technical leadership for propulsion subsystem stress analyses. The role bridges detailed finite-element modeling with design-review participation, ensuring that stress analysis meets program performance, reliability, and safety requirements.Advanced Stress Analysis• Lead static, dynamic, and fatigue analyses using linear and non linear solutions in Siemens NX.• Develop and validate high-fidelity FEM models (meshing strategy, material definition, boundary conditions).• Perform load-case generation and factor-of-safety assessment for critical structuresDesign Integration & Trade Studies• Translate system-level requirements into detailed stress-analysis specifications.• Provide design-size recommendations, reinforcement concepts, and material substitutions to meet weight-strength targets.• Participate in multidisciplinary trade studies (structure-thermal, structure-propulsion, etc.).Verification & Validation• Define test-article requirements, instrumentation layout, and test procedures for ground-test and flight-test campaigns.• Correlate test data with analytical predictions, update models, and document discrepancies.Technical Leadership & Mentorship• Own one or more analysis work-packages from concept through release.• Review and provide constructive feedback on models, reports, and deliverables.Documentation & Reporting• Produce clear, concise analysis reports, design briefs, and risk-mitigation packages.• Maintain configuration-controlled analysis files.• Present findings at design reviews (DDRs, CDRs, PDRs).Continuous Improvement• Evaluate emerging analysis methods, software updates, and industry best practices.• Contribute to internal technical standards, templates, and lessons-learned databases.Desired skills• Master's degree in a structural-analysis-focused discipline.• Experience with composite-material modeling and laminate theory.• Exposure to aerospace programs such as aircraft, UAV, missile, or space platforms.• Knowledge of model-based systems engineering (MBSE) tools (SysML, Cameo).
