Aerospace Engineer

The role

You will shape the aerodynamic and performance characteristics of next-generation composite aircraft. The role involves CFD modeling, aerodynamic optimization, performance analysis, and test correlation.

What you will do

• Design and validate aerodynamic surfaces, configurations, and control geometries using CFD analysis and historical data
• Support flight dynamics modeling and simulation for stability, control, and performance assessment
• Provide input on propulsion integration, cooling airflow, and control surface sizing
• Work with mechanical and manufacturing engineers to ensure aerodynamic designs are practical and efficient to produce
• Conduct aerodynamic load analyses to ensure the airframe is supported
• Create and maintain aerodynamic databases, performance models, and engineering documentation
• Correlate CFD and analytical predictions with flight test data
• Participate in flight testing and data review to compare measured results with predicted performance
• Aid in the development of flight simulation models

Required qualifications

• Proficiency with CFD tools such as ANSYS Fluent, Star-CCM+, XFLR5
• Experience using CAD software such as Fusion 360, SolidWorks, CATIA, or NX for geometry creation and surface preparation
• Strong understanding of aerodynamics, stability and control, and aircraft performance
• Familiarity with mesh design and refinement including fluent meshing
• Working knowledge of structural analysis and load validation
• Ability to interpret flight test data and create analytical performance models
• Understanding of composite design and manufacturing methods for aerodynamic surfaces
• Independent, practical engineer comfortable in a hands-on development environment

Nice to have

• Experience with flight testing, data acquisition, or post-flight data analysis
• Experience with X-Plane aircraft design
• Background in seaplane design
• Experience with wind tunnel or scaled model testing
• Programming skills in Python or MATLAB for CFD and performance automation
• Basic experience with FEA for assessing load paths or aerodynamic-induced stresses
