Job summary

Infinite Orbits in Toulouse seeks a Structural Analysis Engineer to own analysis across satellite subsystems and the integrated spacecraft platform. You will bridge Nastran-based FEM work with physical testing to ensure performance and interface consistency.

You will collaborate with the Mechanical Architect to define load paths, develop and validate FEM models, and lead design verification through PDR/CDR/FRR, including extensive test campaigns.

Qualifications

• Master’s or PhD in Aerospace, Mechanical Engineering, or related field.
• 3-7+ years of experience in structural analysis.
• Strong expertise in Nastran, with Femap as preferred pre/post-processor.
• Proven experience working at both subsystem and full system (platform) level.
• Solid understanding of structural dynamics, load paths, and interface behavior.
• Hands-on experience with test definition, execution support, and correlation.
• Experience taking hardware through full lifecycle (design → integration → test → qualification).
• Knowledge of metallic and composite structures.

Responsibilities

• Own structural analysis for satellite subsystems (e.g., payload, avionics, propulsion support structures) and the integrated spacecraft platform.
• Collaborate with the Mechanical Architect to define load paths, structural concepts, and overall architecture.
• Develop and maintain detailed FEM models using Nastran (Femap preferred) at component and full-system levels.
• Perform linear and nonlinear analyses: static, modal, random vibration, shock, and coupled loads.
• Define and manage load cases for launch, separation, transportation, and in-orbit environments.
• Ensure load path continuity and interface consistency across subsystems and spacecraft level.
• Lead structural sizing, margin assessment, and design optimization across multiple levels of integration.
• Define, support, and interpret structural test campaigns: sine and random vibration, shocks, static load testing.
• Correlate FEM results with test data and continuously improve model fidelity.
• Support system-level verification and qualification activities.
• Contribute to design reviews (PDR, CDR, TRR, FRR) with clear technical justification.
• Establish best practices for modeling, margins, and correlation within the team.
