Structure Design Engineer

As a Structure Design Engineer at SkyDrive, you will own the development of primary and secondary airframe structures for a multicopter eVTOL. Your objective is to engineer a lightweight, optimized airframe that adheres to airworthiness certification standards, ensuring robust structural integration. You will design structural topologies, create 3D models in CATIA V5, and apply DFM principles.

Responsibilities

• Airframe Structural Design: Develop optimized structural topologies with clear, continuous load paths. Validate design feasibility against weight and strength requirements. Develop detailed 3D models of airframe structures utilizing CATIA V5. Execute advanced surfacing (Generative Shape Design), solid modeling, and large assembly management to ensure robust Digital Mock-Ups (DMU). Apply Design for Manufacturing (DFM) principles to ensure designs are producible. Create engineering drawings (2D) with appropriate tolerance stack-up analysis based on GD&T.
• Composite Design & Optimization: Develop primary and secondary airframe structures utilizing advanced composite materials (CFRP) and lightweight metallic alloys. Define and optimize composite laminate architectures to maximize structural efficiency and adhere to strict mass targets.
• Systems Integration (Packaging): Design optimized structural interfaces and support assemblies to ensure secure integration while maintaining the global stiffness and strength of the primary structure.
• Master Geometry Management: Drive "Upstream CAD" methodologies, managing top-down design architecture and master geometry files to ensure data consistency across the engineering team.

Requirements

• Educational Background: Bachelor’s or master’s degree in aerospace, Mechanical, or Structural Engineering.
• CAD Mastery: Expert-level proficiency in CATIA V5 (Generative Shape Design, Part Design, Assembly Design). Experience with CPD (Composite Part Design) is a strong plus.
• Industry Experience: 3+ years of experience in structural design within the Aerospace industry (highly preferred) or Automotive.
• Composite Knowledge: Deep understanding of composite materials, composite airframe conception and manufacturing processes.
• Engineering Fundamentals: Strong understanding of mechanics of materials, load paths, and weight optimization techniques.

Nice to have

• eVTOL/Drone Experience: Specific experience designing multicopters or VTOL aircraft.
• Certification Knowledge: Familiarity with certification specifications such as JCAB, EASA (SC-VTOL), or FAA (Part 23).
• PLM Experience: Proficiency in using ARAS for product lifecycle management.
• Rapid Prototyping: Experience in a startup environment where agility and rapid design iterations are required.

Benefits

• 115 days off per year Saturday / Sundays / New year holidays（12/29～1/3） / Company designated holidays）
• Annual paid leave
• Refresh leave (Granted after 1, 3, 4, 5 years of service)
• Estimated Annual Salary: JPY 6,850,000- JPY 10,280,000
• Monthly Salary: JPY 571,000- JPY 857,000
• Includes fixed overtime pay for 45 hours, amounting to JPY 197,680- JPY 296,697
• *Additional overtime pay will be provided for hours exceeding the fixed overtime.
• To be determined based on skills, experience, and abilities
• Commuting allowance, business trip allowance, moving allowance, etc.
• Relocation Packages
• *There are some conditions.
• Health insurance
• Employee pension (according to Japan standards)
• Employment insurance
• Worker’s accident compensation insurance
