Stress Analysis Senior Engineer

Stress Analysis Senior Engineer | Lockheed Martin

The 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 structures

Design 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).
