FEA (Finite Element Analysis) or CAE (Computer-Aided Engineering)

GENERAL JOB SUMMARY:

The FEA / CEA Engineer is responsible for performing structural, thermal, vibration, fatigue, and computational engineering analysis in support of the design, development, qualification, and production of aerospace propulsion systems and components.

This position works closely with Design Engineering, Product Engineering, Manufacturing, Quality, Test, and Program Management to validate designs, identify technical risks, resolve hardware issues, and ensure products meet performance, reliability, manufacturability, and customer requirements.

The ideal candidate is a hands-on engineer capable of translating analytical results into practical engineering decisions and supporting hardware from initial concept through testing and production.

Essential Duties and Responsibilities

Structural & Multiphysics Analysis

• Develop and perform finite element and computational analyses for aerospace components, assemblies, and propulsion systems.
• Perform linear and nonlinear structural analysis, including stress, strain, deformation, contact, and load-path evaluations.
• Conduct thermal and thermal-stress analysis for components operating in high-temperature environments.
• Perform modal, vibration, harmonic, and dynamic response analysis as required.
• Evaluate component fatigue life, durability, fracture risk, and structural margins.

Analysis Modeling, Verification & Design Substantiation

• Develop appropriate analytical models, assumptions, boundary conditions, material properties, loading conditions, and acceptance criteria.
• Perform mesh development, convergence studies, sensitivity studies, and model verification.
• Calculate and document Factors of Safety and Margins of Safety against applicable design requirements.
• Support rotating-component analysis including shafts, turbine components, bearings, housings, and other propulsion-system hardware.

Test Correlation & Validation

• Correlate analytical predictions with component, subsystem, and engine test results.
• Support instrumentation and test planning required to validate analytical models.
• Support Design Reviews, DFMEA/PFMEA activities, qualification testing, First Article Inspection, and production readiness.

Failure Investigation & Corrective Action

• Perform root-cause analysis of component failures, test anomalies, nonconformances, and field-return hardware.
• Support RCCA, FRACAS, NCR, and corrective-action activities with engineering analysis and supporting data.
• Evaluate supplier-manufactured components when dimensional, material, or manufacturing conditions deviate from engineering requirements.
• Provide technical disposition recommendations for nonconforming hardware when supported by engineering analysis.

Design Engineering & Product Development Support

• Provide analysis supporting design changes, configuration changes, ECOs, and product improvements.
• Work directly with Design Engineering to optimize geometry, materials, tolerances, weight, performance, and durability.

Technical Documentation & Continuous Improvement

• Define and develop modeling and simulation best practices and techniques
• Develop concise engineering reports documenting assumptions, methods, results, conclusions, risks, and recommendations.
• Maintain analysis files, models, calculations, and technical documentation in accordance with configuration-management requirements.
• Support continuous improvement of engineering analysis methods, tools, templates, standards, and validation processes.
