• Proficiency with Finite Element Analysis for quasi-static loading and dynamic analysis with strong fundamentals of basic hand calculations.
• Solid understanding of free-body diagrams, load paths, and classical analysis techniques
• Proficiency with analytical methods for structural verification of mechanical joints (lugs, bolts, and bonded joints).
• Ability to build and validate finite element models including linear-static, buckling, modal, and non-linear as needed
• Conduct analysis of loads, margins of safety, and failure modes of parts and assemblies
• Ability to interpret engineering requirements, specifications, and relevant aerospace documentation standards (MIL-STD-810, MIL-STD-8591, etc.).
• Strong analytical mindset with attention to accuracy, validation, and engineering rigor.
• Must be a US citizen and able to obtain and maintain a U.S. Secret-level security clearance.
• Comfortable working in a fast-paced, team-oriented engineering environment.

Preferred Qualifications:

• 15 years of structural analysis with aerospace metallic or composite structure experience.
