️ Composite Design Engineer - Aircraft Cabin Interior Structures (M/F)
Île-de-France (France)
Strategic Aerospace Project - Cabin Structures Only (Not Primary Structure)
Work Visa Sponsorship Available

Are you experienced in designing aircraft cabin structures such as seats, linings, monuments, or partitions—not primary structure?
Are you ready to work on high-stakes, innovative aerospace projects in a multicultural environment? If yes, let's talk.

What you will do

As part of an engineering team focused on aircraft cabin interiors, you'll be involved in composite structural design and integration for complex cabin components.

Key Responsibilities:
Design and develop composite components for cabin interiors (seating, linings, PSU, monuments, partitions, etc.)

Generate detailed 3D models, BoMs, and integration studies using CATIA V5

Ensure design for manufacturability, compliance with aerospace standards (CS25/FAA), and ergonomics

Participate in design reviews and support engineering milestones (PDR, CDR, ITCM)

Work closely with cross-functional teams: manufacturing, certification, supply chain, and customer interface

Develop and implement internal design guidelines and best practices

Support composite tooling, prototyping, and production integration

**Profil recherché**:
What we expect

️ Mandatory:
Minimum 2 years of professional experience (excluding internships or apprenticeships) in aircraft cabin interior structural design

Hands-on experience with composite materials and cabin structure integration

Good command of CATIA V5, ENOVIA or SmarTeam is a plus

Understanding of LOPA, seating layout, and interior assembly line environment

Familiarity with certification constraints (CS25, FAA) and design to cost/mass

Soft Skills:
Autonomous, problem-solver, and proactive mindset

Strong team player with excellent communication

Capability to work under tight deadlines in a multicultural team

Languages:
French (professional level) - required for communication with local teams and workshops

English (fluent) - required for documentation and international collaboration
