PURPOSE OF THE POSITION

Within the Network & Cybersecurity Services (NCS) division of GBS IT, the Network And Connectivity (NAC) department is composed of the SDM Team, the Expertise Team and the Network Operating Center (NOC) team.

The NOC serves as the operational hub for our Network and Security infrastructures. Our mission is to ensure performance and security across all network and security infrastructures, whether they are in data centers, the cloud, or remote sites (examples: ‘Highway to Cloud’ interconnection infrastructures in AWS/Azure, Cloud Proxy and VPN services with ‘Zscaler,’ Software-Defined WAN, LAN, and Wi-Fi services, etc.).

The NOC, consisting of over 40 professionals, is structured into two distinct yet complementary teams:

• NOC Back Office: This team of technical experts focuses on the day-to-day operation of services.
• NOC Front Office: This team provides crucial support to the Back Office, focusing on industrialization, process management, and operational oversight of infrastructure and managed services

The NOC Level 3 will be hosted within GBS IT in Mexico. Its missions will primarily be ‘global’ for the ENGIE group, but employees will also be involved in supporting ‘local’ operations at GBS IT Mexico.
