Structural Stress & Certification Team lead

This is a mid-to-senior engineering leadership role responsible for proving the structural integrity, safety, and airworthiness of SkyDrive's eVTOL aircraft. Reporting to the Director of the Structure Group, you will lead and manage two critical technical pillars: Stress Analysis and Certification & Structural Testing. Your team ensures that the ultra-lightweight carbon-fiber airframe, rotor structures, and integrated battery/powertrain mounts meet all civil airworthiness strength, fatigue, crashworthiness, and regulatory compliance requirements. You will bridge the gap between structural modeling, physical testing, and formal Type Certification (TC) approval with civil aviation authorities.

Responsibilities

• Direct and review global and detailed stress analysis across metallic and composite (CFRP) airframe structures using both Finite Element Methods (GFEM/DFEM) and classical hand calculations.
• Oversee static, fatigue, damage tolerance, dynamic crashworthiness, and bird-strike analyses for primary structures, rotor systems, and battery mounts.
• Hold technical sign-off authority for internal Margin of Safety (MoS) reviews, structural substantiation documents, and Material Review Board (MRB) / Non-Conformance (NCR) dispositions.
• Drive the structural certification roadmap in close coordination with SkyDrive’s central Certification Department.
• Lead the creation, review, and formal submission of structural compliance summary reports, structural substantiation dossiers, and Means of Compliance (MoC) under civil airworthiness regulations (JCAB, FAA, and EASA—e.g., SC-VTOL, Part 23/27/29 equivalents).
• Interface directly with aviation authority auditors and designated engineering representatives regarding structural strength, fatigue, and flutter compliance.
• Oversee the complete structural test execution strategy following the aerospace "Building-Block Approach" (coupon, element, sub-component, and full-scale airframe levels).
• Direct the preparation of test proposals, test procedures, instrumentation requirements (strain gauges, load cells), and post-test summary reports.
• Lead the correlation efforts between physical test data and analytical FE models to validate structural safety factors and refine analysis methodologies.
• Partner closely with the Structure Design Team to drive weight reduction and trade studies without compromising structural margins or manufacturing feasibility.
• Collaborate with the Materials & Processes (M&P) team to integrate material allowables, environmental knock-down factors, and BVID (Barely Visible Impact Damage) criteria into stress predictions.

Requirements

• Education: Bachelor’s or Master’s degree in Aerospace, Aeronautical, Structural, or Mechanical Engineering.
• 8–12+ Years of Aerospace Experience: Deep expertise in structural analysis, structural testing, and airworthiness certification within an aircraft OEM, rotary-wing OEM, or Tier-1 aerospace supplier.
• 3+ Years of Technical Leadership / Management: Proven experience managing engineers, conducting performance reviews, and driving team deliverables under tight program schedules.
• Civil Certification Track Record: Direct experience preparing structural substantiation documentation and demonstrating compliance for a civil aircraft Type Certification (TC) or major supplemental certification project (JCAB, FAA, or EASA).
• Advanced Stress Analysis Mastery: Hands-on mastery of classical aerospace hand calculations and industry-standard FEA software (e.g., NASTRAN/PATRAN, Abaqus, ANSYS, HyperMesh).
• Composite Mechanics Expertise: Extensive experience evaluating composite structures (CFRP, sandwich panels, bonded joints, lug/fastener analysis) and dynamic fatigue/damage tolerance.
• Structural Testing Execution: Practical experience overseeing static, drop/crash, or fatigue testing of aircraft components.

Nice to have

• Experience with eVTOL, helicopter, or light aircraft airframe structural substantiation.
• Proficiency with CATIA V5/Siemens NX (for geometry review and load extraction) and PLM systems (Teamcenter/ENOVIA).
