• Aerodynamic Synthesis & Configuration: Propose and define the aerodynamic shapes of the eVTOL airframe and lifting surfaces to meet performance targets.
• Advanced Optimization: Drive the design process using Multidisciplinary Optimization (MDO) tools to manage strict trade-offs between aerodynamic efficiency, structural weight, and power electronics.
• Blade & Rotor Design: Lead the design and optimization of key components, specifically focusing on the complex physics of multi-rotor environments and unsteady aerodynamics.
• Physics-Driven Iteration: Use CFD not just for validation, but as a creative tool to refine designs and resolve performance bottlenecks at an early stage.
• Design Validation & Closing the Loop: Plan and lead wind tunnel tests and flight test data acquisition to validate your designs and adjust mathematical models for real-world behavior.
• Certification Leadership: Manage the aerodynamic design process from requirements definition through to certification compliance (e.g., CS.23/25 or CS.27/29).

Essential Skills

• Design Experience: 7+ years of experience in aerodynamic design and optimization (not exclusively analysis).
• Technical Authority: Proven track record in Aircraft Concept Design and the ability to discuss technical trade-offs across structures, propulsion, and flight control.
• Complex Interactions: Deep understanding of Aeroelasticity and Fluid Structural Coupling (FSI) to account for airframe flexibility
• Advanced Tools: Mastery of coupled simulations for multi-rotor environments (e.g., CAMRAD II, FlightLab).
• Education: Master’s or Ph.D. in Aerospace Engineering or equivalent.

Desirable Skills

• Those who have a deep knowledge of electric propulsion systems, flight control systems, system integration, and a background in VTOL design
• Experience managing all technical aspects of aircraft aerodynamic design from requirements definition to certification (CS.23/25 and/or CS.27/29)
• Experience setting aerodynamic loads on blades, rotor, and other aircraft components
• Knowledge and experience in aeroelasticity and Fluid Structural Coupling (FSI) tools
