In order to achieve our common goals, we count on you

• Serve as the technical point of convergence for multi-entity satellite missions involving separate upstream and downstream contractors.
• Define, maintain, and validate system-level architecture, interfaces, and end-to-end performance requirements across mission domains (satellite, ground segment, operations, and data services).
• Oversee technical execution and system integration across participating contractors, ensuring schedule and performance alignment without directly managing their teams.
• Review and evaluate technical deliverables from satellite manufacturers, ground segment providers, and data service integrators.
• Ensure interoperability and compliance with program objectives, regulatory constraints (e.g., ECSS, ITU, national policies), and mission requirements.
• Lead and participate in cross-domain technical reviews (e.g., SRR, PDR, CDR, ORR), providing system-level validation and integration perspectives.
