• Lead requirement allocation and ensure traceability.

Integration & Validation

• Drive co-engineering workshops with stakeholders (payload, ground network, antennas, mission chain).
• Oversee integration and verification activities (FlatSat, end-to-end IVV).
• Perform architecture trade-offs and performance analysis (coverage, latency, throughput).

Compliance & Coordination

• Ensure compliance with security and certification frameworks (DR-SF, ANSSI/DGA).
• Act as technical interface with suppliers and subcontractors.
• Support procurement processes and evaluate supplier compliance.
• Produce high-quality technical documentation (ICD, CONOPS, system specs).
• Contribute to optimization roadmaps and integrate new technologies.
• Provide technical expertise and training to customer-facing teams.

What you will need

• Degree in Aerospace Engineering, Telecommunications, or related field.
• 5–10 years of experience in space system engineering (LEO experience is a plus).
