Aerodynamic Design Engineer

このポジションは、次世代eVTOL航空機の空力アーキテクチャを主導する空力設計エンジニアを募集しています。従来のシミュレーション業務とは異なり、設計ループを所有し、複雑な流体力学を解釈して機体、ブレード、ローターの形状を定義します。概念要件から飛行可能な高効率設計への移行をリードし、安定性、制御性、構造的制約のバランスを取ります。

Responsibilities

• We are seeking a visionary Aerodynamic Design Engineer to spearhead the aerodynamic architecture of our next-generation eVTOL aircraft. Unlike a traditional simulation role, this position focuses on owning the design loop—interpreting complex fluid dynamics to define the shapes of airframes, blades, and rotors. You will lead the transition from conceptual requirements to flight-ready, high-efficiency designs that balance stability, controllability, and structural constraints.
• 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).

Requirements

• 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.

Nice to have

• 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
• Knowledge in coupled simulations of rotor-dynamics and aerodynamics for multi-rotors environment such as CAMRADII, Flight Lab.

Benefits

• 115 days off per year（Saturday / Sundays / Newyear holidays（12/29～1/3） / Company designated holidays）
• Annual paid leave
• Refresh leave (Granted after 1, 3, 4, 5 years of service)
• Commuting allowance, business trip allowance, moving allowance, etc.
• Relocation Packages
• Health insurance
• Employee pension (according to Japan standards)
• Employment insurance
• Worker’s accident compensation insurance
