• Familiarity with aerospace standards and certification processes (e.g., FAA, NASA, MIL).
• Scripting or programming experience (Python, MATLAB) to automate analysis workflows.
• Experience supporting hardware testing or flight operations

Responsibilities

• Perform structural analysis of aerospace components and assemblies under static, dynamic, thermal, and fatigue loading.
• Use hand calculations and finite element models to support rapid design iteration.
• Work closely with design engineers to influence geometry, materials, and load paths early in the design process.
• Correlate analysis with test data and support structural testing and qualification efforts.
• Exemplify technical excellence and be accountable for your work.
• Communicate technical content in an efficient and effective manner to partner teams.

Benefits
