Senior System Engineer (m/f/d) - Airframe & Propulsion

As a Senior Airframe & Propulsion System Engineer, you will be responsible for definition, validation and review of airframe structures and propulsion systems for advanced UAS platforms. You will be working closely with stakeholders from the Certification, System Test Engineering, Flight Testing departments to ensure project optimal aerodynamic performance, structural integrity, and propulsion efficiency, while maintaining compliance with aerospace and defense standards.

What is your Day to Day Mission:

• Define and manage airframe and propulsion system requirements, ensuring traceability throughout the lifecycle.

• Preparation of technical documentation for systems/subsystems (e.g. specifications, integration and test plans, test specifications for integration and acceptance tests, design descriptions).

• Ensure clarity and consistency in documentation for global teams and certification authorities.

• Perform trade studies for materials, structural configurations, and propulsion technologies considering weight, performance, safety, and reliability.

• Ensuring compliance with development and production processes (system) for airframe and propulsion systems.

• Support structural analysis (FEM), aerodynamic simulations (CFD), and propulsion performance modeling.

• Collaborate with certification teams to meet standards and guidelines such as ARP4754, ARP4761, DO-160, (EU) 2019/945 and its EN 4709 series, MIL-STD-810, and relevant STANAGs 4703, 4671, 4370, 4866, 4867 and 4868.

• Act as a technical liaison between airframe designers, propulsion engineers, and external suppliers.

• Oversee integration of propulsion systems (electric or hybrid) into UAS platforms.

• Support environmental qualifications (temperature, vibration, EMI/EMC) and flight testing for airframe and propulsion systems.

• Mentoring and knowledge transfer

What you bring to the team:

• Degree in Aerospace Engineering, Mechanical Engineering, or related field.

• 5+ years of experience in Airframe Design and Propulsion System Integration, preferably in aerospace or defence.

• Strong understanding of structural analysis, aerodynamics, propulsion systems, and materials engineering.

• Familiarity with CAD tools (CATIA, NX, SolidWorks), FEM/CFD software.

• Familiarity with requirements management tools (e.g., DOORS, Polarion, JAMA) and version control systems.

• Knowledge of certification standards for airframe and propulsion systems.

• Excellent problem-solving. Strong communication and documentation written skills in English (German is a plus).

• Enjoyment of working in a collaborative team environment.
