Structural Design Engineer, Spectrum (m/f/d)

The role

You will shape the structural architecture of next-generation reusable launch vehicles. This role involves bridging vehicle design, structural analysis, and integrated system layout to enable architecture trade studies and development decisions.

What you will do

• Define and evaluate vehicle-level structural loads, load paths, and critical sizing cases.
• Develop structural concepts and perform sizing activities using first-principles, reduced-order models, and finite element analyses.
• Translate reusable launcher architecture concepts into CAD layouts.
• Assess the integration of primary structures with tanks, fluid systems, aerodynamic surfaces, landing systems, mechanisms, and other subsystems.
• Create and maintain structural models to evaluate feasibility, mass, stiffness, interfaces, and vehicle performance.
• Identify structural drivers, design constraints, and cross-system dependencies.
• Support multidisciplinary vehicle development by balancing performance, operability, manufacturability, and reuse.
• Communicate structural implications, trade-offs, and recommendations to engineering stakeholders.

Required qualifications

• 3-7 years of experience in aerospace, launch vehicles, aircraft structures, or other highly engineered structural products.
• Experience developing structural concepts and layouts from requirements through preliminary design.
• Experience contributing to vehicle-level architecture trades and multidisciplinary system development.
• Strong understanding of structural mechanics, load paths, structural sizing, and vehicle-level structural behavior.
• Proficiency with FEM tools (e.g. Abaqus, Nastran, Ansys, HyperWorks).
• Ability to develop reduced-order models and engineering approximations from higher-fidelity analyses.
• Strong CAD skills (e.g. CATIA, Siemens NX or comparable).
• Systems-thinking mindset.
• Structured problem solver with sound engineering judgment.
• Fluent in English, both written and spoken.

Nice to have

• Experience with reusable launch vehicles, recovery systems, landing systems, or deployable mechanisms.
• Fluent in German

Benefits

• Employee Participation Program: virtual company share program
• 30 days of vacation
• Company pension plan with 20% employer contribution after probation period
• Subsidised lunch
• Rental clothing with laundry service
• Sport Clubs membership (EGYM Wellpass)
• Individual learning allowance granted after probation period
• Childcare allowance
• Flexible mobility budget: Deutschlandticket, JobRad bicycle leasing, FINN JobAuto, or a fuel allowance
