Senior Mechanical Engineer, Stress Analysis

Were looking for a structures engineer with strong design and analysis fundamentals someone eager to learn and flexible enough to take on whatever a fast-moving hardware program throws at them. Youll work in an exciting fast-paced environment tackling some of the most challenging structural problems in aerospace.

Responsibilities

• Perform structural analysis (static buckling and modal) on airframe gondola and equipment mount structures using FEA tools (FEMAP/NX Nastran or equivalent)
• Develop and maintain finite element models including mesh generation load case setup and post-processing of results
• Perform hand calculations to size structures verify FEA results and support quick-turn design trades
• Size and design structural components and assemblies from concept sketches through detailed CAD
• Correlate analytical models against test data (static load tests modal surveys ground vibration testing)
• Support design trade studies weighing weight strength manufacturability and cost
• Document analysis methodology assumptions and results in formal engineering reports
• Collaborate with Systems Avionics Soft Structures Materials & Testing and Manufacturing teams to integrate structural designs with the broader vehicle
• Support fabrication assembly and test of structural prototypes and hardware
• Investigate and resolve structural issues found during build test or field operations
