We are seeking a highly experienced Senior Structural Analysis Engineer to join our aerospace engineering team, focusing on the structural integrity and certification of eVTOL aircraft. In this role, you will plan and execute structural analysis and testing strategies, lead detailed analyses of complex CFRP and metallic components, and develop critical certification documentation for authorities like EASA and FAA. You will also act as a technical reference, providing guidance and mentoring to less experienced engineers to raise the overall engineering standard.

Responsibilities

Methodology and Execution: Plan and execute structural analysis and testing strategies in accordance with structural assurance requirements (e.g., Building Block Approach) for eVTOL certification.
Technical Excellence: Lead detailed structural analyses of complex eVTOL components (CFRP and metallic), ensuring full compliance with strength, stiffness, fatigue, damage tolerance, and impact resistance requirements.
Advanced Analysis: Evaluate complex stress, strain, and deformation characteristics under static, dynamic, vibratory, and thermal loads.
Certification Documentation: Develop and maintain critical documentation required for certification (e.g., EASA/FAA), including stress reports, test plans, and compliance matrices, acting as a key technical contributor during authority audits.
Peer Mentoring: Act as a technical reference within the team, providing guidance, peer review support, and mentoring to less experienced engineers to promote best engineering practices.

Requirements

Extensive experience (over 5 years) in structural analysis in the aerospace industry (preferably with composite aircraft, helicopters, or eVTOL programs).
Solid experience in calculation, analysis, and reporting on complex metal and CFRP composite structures.
Advanced proficiency in Nastran (for linear/non-linear static and dynamic analysis) and LS-DYNA (for explicit dynamics/impact resistance).
Deep knowledge of mechanics of materials, classical manual calculations, composite failure criteria, and fatigue/damage tolerance (DTA) principles.
Proven ability to independently conduct technical projects and foster a collaborative environment.

Nice to have

Deep understanding of specific certification frameworks (e.g., EASA SC-VTOL, FAA Part 23/27) and guidelines for composites (e.g., CMH-17, AC 20-107B).
Experience in structural requirements analysis and development of comprehensive structural certification and testing plans.
Experience in planning structural modifications and root cause analysis for failures or nonconformities in tests.
Extensive knowledge of aeronautical engineering in general, enabling effective interdepartmental collaboration (aerodynamics, systems, testing).
