As a member of the network and telecommunications support team of the Communications Systems Group (IT-CS), you will be responsible for the smooth and efficient operation of network and telecom services at CERN. The Communication Systems group supports network infrastructure that includes a campus network (fixed and Wi-Fi) with over 20,000 actives devices, two datacentres housing over 10,000 servers with high-speed connections to other research centres, as well as fixed and mobile telephony, TETRA digital radio services and a LORA based IoT service.

We use software developed in-house to manage and configure the network, as well as the Spectrum NMS for real-time monitoring. Developing a good working knowledge and understanding of these systems will be an important aspect of the role.

• Monitoring incidents on the network infrastructure, follow-up with experts of the affected services;
• Advanced user support for complex requests and incidents reported by users;
• In-depth investigation and resolution of highly technical networking and telecom issues affecting various types of systems at CERN (industrial controllers, high performance computing applications etc.), in collaboration with experts from IT or other departments;
• Preparation and improvement of operational processes and procedures and liaison with the contractors responsible for following these procedures;

Experience:

• Experience in the fields of networking and/or telecommunications.
• Experience in a service provider role in a technical environment.
• Experience in analysing complex technical problems and finding means to resolve them.
• Experience of coordinating work with external providers and subcontractors would be an advantage, as would experience in developing simple scripts (Bash, Python).
