Description du poste

Nous proposons un poste à responsabilités au sein d'un projet technique unique en Europe dans l'écosystème des start-ups aérospatiales : des cycles courts, du laboratoire au vol.

Les missions de l'Ingénieur Matériaux Senior (H/F)

• Technical strategy: define material families and process options across all programmes.
• Supervise the supplier & lab coordination.
• Make or Buy decision Team leadership & competence: leading entire Soft Structure domain at Zephalto, lead junior materials engineers: review their designs, calculations, and documentation; provide feedback.
• Specifications: author and approve all material and process documents across programmes. Ensure consistency with certification requirements (CS-31GB, Special Conditions).
• Design oversight: review all materials-related design decisions (material choice, pattern layout, welding technology, margins).
• Serve as technical authority in design reviews.
• Process qualification: own the qualification strategy for welding and assembly processes — define test plans, approve results, release process procedures.

Technical competencies

• Materials: deep knowledge of film families (PE, PA, PET, PTFE, multilayer laminates), elastomers, and technical textiles.
• Welding processes: expert in thermal sealing (impulse, bar, controlled temperature), RF welding, and ultrasonic techniques. Ability to troubleshoot process failures and optimize parameters.
• Extreme environment expertise: thermal behavior at −90 °C to +80 °C, UV aging, ozone attack, mechanical creep, cold‑brittleness, visco‑elastic effects.
• Thermo‑optical properties: absorptivity, emissivity, solar absorptance; thermal modeling; radiant equilibrium calculations.
• Characterization & testing: ASTM/ISO standard test methods; ability to specify tests and interpret results.
• Thermo‑optical properties: absorptivity, emissivity, solar absorptance — application to extreme thermal environments.
• Technical textiles & sewing: stitching design, seam assembly, reinforcement patterns — a significant asset.
• Regulatory awareness: basic understanding of aerospace traceability, configuration control, and documentation rigor (EN 9100 / Part 21 context) — will be developed on the job.

Leadership & Professional competencies

• Technical authority: comfortable making material/process decisions under uncertainty; able to defend rationale to regulators and auditors.
• Supplier management: contract negotiation, audit protocols, quality improvement.
• Mentorship: ability to teach junior engineers, provide constructive feedback, and develop technical competence in the team.
• Strategic thinking: long‑term material roadmap, cost‑quality‑schedule trade‑offs, supply‑chain risk, technology positioning.
• Documentation: clear technical writing, traceability discipline, revision strategy, natural alignment with QMS rigor.

Education & Experience

• Engineering degree (Bac+5 equivalent) in materials science, polymers, or textiles; or equivalent hands‑on experience in aerospace, space, medical device, or advanced packaging roles.
• 8+ years in soft polymer materials and/or welding process development.
• Experience with exposure to a regulated environment (aerospace, space, medical) is required.
• Leadership: 3+ years in a technical leadership or domain‑lead role (mentoring, design authority, supplier management).
• Preferred background: aerospace, space, balloons, technical textiles, medical (welded pouches), or technical packaging roles.
