Responsibilities

• Design, develop, test, and maintain high-reliability onboard flight software in compliance with product assurance and safety standards.
• Collaborate with cross-functional stakeholders to define, refine, and manage software requirements across all onboard satellite systems.
• Contribute to the definition and evolution of onboard software architecture, supporting both laboratory-based validation environments and in-orbit operational systems.
• Develop and implement robust Fault Detection, Isolation and Recovery (FDIR) strategies to ensure resilience and autonomy of onboard systems.
• Support the planning, coordination, and delivery of new software features and upgrades, working closely with external suppliers and development partners.
• Champion strong configuration management practices across all onboard software components to ensure traceability, integrity, and control.
• Define and drive verification and validation strategies, ensuring comprehensive testing and high confidence in flight software performance.
• Participate in end-to-end verification and validation activities for onboard systems and flight software.
