What You’ll Do
- Contribute to the architecture, development and maintenance of satellite control software systems
- Ensure consistency, maintainability and performance of software applications across the ground segment
- Analyze change requests and anomalies, define technical specifications, and coordinate their implementation
- Support software validation, integration and deployment into operational environments
- Define and evaluate software architecture evolutions in line with future operational needs
- Collaborate with contractors in Germany and Spain, ensuring technical follow‑up and delivery quality
- Provide technical expertise and support to satellite operations teams and end users
- Coordinate and supervise software maintenance activities and releases
- Ensure compliance with quality (ISO 9001) and security (ISO 27001) standards
- Maintain proper configuration management and documentation of software systems

Where You’ll Work
Issy‑les‑Moulineaux, Paris. You will work in a highly technical and operational environment dedicated to satellite control systems within the Engineering Department, working closely with engineering and operations teams.
Home office may be considered after completion of the initial training period and subject to operational constraints; however, due to the highly technical and mission‑critical nature of the role, the position is primarily based on‑site.
The role involves
- Collaboration with cross‑functional teams and external partners
- Work in a mission‑critical environment requiring high availability and reliability
- Participation in a 24/7 on‑call rotation to ensure continuous system operations
- A dynamic setting combining engineering, operations and real‑time system support, with direct impact on satellite fleet performance
