Job description

Stress Engineer – Preliminary Sizing (Part 23/25 Fuselage)

We are seeking a highly skilled Stress Engineer with strong experience in the preliminary sizing phase of Part 23/25 metallic fuselage structures. The successful candidate will play a key role in shaping the structural architecture of the aircraft by working closely with the design team in a fast-paced development environment. This role requires deep technical expertise, sound engineering judgment, and the ability to translate conceptual requirements into robust structural solutions.

Key Responsibilities

• Perform preliminary sizing of metallic fuselage structure components in accordance with Part 23/25 requirements.
• Collaborate closely with the design team to guide structural architecture, joint design, load paths, and material/geometry selections.
• Interpret loads derived from the aircraft GFEM and assess their impact on structural sizing.
• Develop or refine engineering tools, methods, and calculation templates to improve analysis efficiency and consistency.
• Provide design guidelines for a fatigue- and damage-tolerant structure, ensuring alignment with certification requirements and best practices.
• Prepare technical documentation, including calculation reports, design justifications, and compliance evidence.
• Work within an iterative, fast-paced environment requiring proactive communication and rapid adaptation to design evolution.

Qualifications

• 10+ years of experience in aerospace structural analysis, including preliminary sizing of metallic fuselage or airframe structures.
• Strong knowledge of classical structural design and analysis methods, including familiarity with industry-standard references such as Bruhn, Niu, and Roark's Formulas for Stress and Strain.
• Proficiency with CATIA / 3DEXPERIENCE (3DX) CAD environments.
• Understanding of fatigue and damage tolerance concepts and their application in metallic airframe design.
• Experience working with internal and external loads (from GFEM or equivalent).
• Strong analytical skills and engineering judgment, with the ability to balance technical rigor and development speed.
• Excellent written and verbal communication skills.
• Programming skills in Python/VBA are considered an asset.
