This is a unique opportunity to make a significant impact within an organization that values growth, teamwork, and professional development.

Who You Are:

You are a highly motivated and rigorous software engineer with a strong background in complex systems and mission-critical environments. You thrive in collaborative and cross-functional settings, and you are comfortable working at the intersection of software engineering, system operations, and infrastructure.

You demonstrate:

• Strong analytical and problem-solving skills, with the ability to handle complex technical challenges
• A structured and methodical approach to software development and maintenance
• A high level of autonomy and responsibility in ensuring system reliability
• Excellent communication skills, enabling you to interact effectively with both technical and operational stakeholders
• A strong commitment to quality, security, and continuous improvement
• Willingness to contribute to on-call rotations and ensure 24/7 operational continuity after gaining sufficient experience in the role

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
• Support satellite launch and in-orbit validation phases
• Contribute to operational continuity, including participation in 24/7 on-call duty rotations

What You’ll Need:

• Degree in Computer Science, Software Engineering, or Electronics
• Proven experience in software engineering for complex or mission-critical systems (satellite control is a strong plus)
• Strong knowledge of:
  • Software architecture for distributed and operational systems
  • Software development lifecycle and maintenance methodologies
  • Programming and technologies such as C, Python, Java, Linux, scripting, Ansible, Nexus, Docker swarm, VMware, databases (MariaDB/Mongo/Influx/ClickHouse), mTLS, REST APIs, cloud/storage technologies
• Experience with system integration and operational environments
• Understanding of software project management principles
• Basic knowledge of satellite communications or similar domains is a plus
• Fully fluent English written and spoken, French and Spanish is a plus
• Strong organizational skills and attention to detail

• Eligibility to work in the European Union is mandatory.

Where You’ll Work:

You will be based in Issy-les-Moulineaux, Paris, in a highly technical and operational environment dedicated to satellite control systems within the Engineering Department, working closely with engineering and operations teams.

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

Home office may be considered after completion of the initial training period and subject to operational constraints. However, given the highly technical and mission-critical nature of the role, the position is primarily based on-site, where access to systems and close collaboration with operational teams are essential.
