Zusammenfassung

Destinus is seeking a Senior Stress Engineer to lead the sizing and structural analysis of pressure-loaded rocket motor components, including metallic and composite motor cases. You will perform analytical and numerical stress analyses across high-pressure, high-temperature environments and define load cases for ignition and dynamic effects.

You will collaborate with propulsion, materials, manufacturing, and systems teams, ensuring safety margins and compliance with aerospace standards while

Qualifikationen

• MSc in Aerospace or Mechanical Engineering or related discipline.
• 5+ years of experience in stress or structural analysis of pressure-loaded aerospace components.
• Experience with rocket motor structures is highly desirable.
• Proficiency in FEA tools (ANSYS/Abaqus/Nastran) and classical hand calculations.
• Fluency in English required; German a plus.

Aufgaben

• Lead the structural sizing and stress analysis of rocket motor pressure structures, including metallic and composite motor cases and pressure-loaded components.
• Perform analytical and numerical stress analyses (linear, nonlinear, buckling, fatigue, fracture, and damage tolerance) for high-pressure, high-temperature environments.
• Define and manage load cases and environments relevant to rocket motor operation, including internal pressure, thermal gradients, mechanical loads, ignition transients, and dynamic effects.
• Develop and apply analysis methodologies for composite motor structures, including laminate theory, failure criteria, and knockdown factors.
• Support material selection and structural concepts with focus on mass efficiency, strength, thermal compatibility, and manufacturability.
• Ensure designs meet required safety factors, margins, and internal or applicable aerospace standards for pressure-loaded rocket hardware.
• Support and interpret structural testing (proof, burst, cyclic or hot-fire-related testing) and correlate analytical predictions with test data.
• Participate in and lead stress reviews, providing clear justification of assumptions, margins, and trade-offs.
• Collaborate closely with propulsion, materials, manufacturing, and systems teams to ensure structurally sound and producible rocket motor designs.
• Author and review stress reports, analysis documentation, and verification evidence.
• Mentor junior engineers and contribute to the continuous improvement of structural analysis methods and tools.
