In this position, you will work closely with the satellite control systems security manager, system/network engineers and satellite engineers, contributing directly to our ongoing projects and initiatives. 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 an engineer or have a five-year degree (or equivalent). You have at least three years' experience in IP/WAN network implementation, operation and maintenance. You also have experience in data network security.

• Manage and monitor services for equipment updates and migrations.
• Participate in the automation of network equipment management.
• Participate in the configuration of the monitoring and alert system. (Zabbix, Elastic Stack)
• Monitor and resolve operational issues in networks and associated monitoring systems.
• Provide on-call support for operations, typically one week every 45 days or so, with telephone or on-site support (Issy-les-Moulineaux) as needed, for the maintenance of main networks and systems.

Technical Role in Network Security

• In collaboration with the satellite control systems security manager, design, organize the technical deployment and maintain the technical solutions resulting from the control Centre’s security measures.
• Implement and continuously improve the security of networks dedicated to satellite control.
• Monitor the actions to be taken to eliminate detected vulnerabilities.
