The IT department will publish soon on the CERN job portal the following Computing Engineer job:

Network Engineer in the Communications Systems (CS) Group, Communication Engineering (CE) Section

Are you a talented network engineer? Does contributing to the improvement of an advanced campus network with high-speed, worldwide connections sound attractive? Join CERN’s Communication Systems Group and make your mark. Take part!

You will join:

  • The Communication Systems (CS) Group, responsible for all aspects of network and telecommunication provision at CERN. We support a campus network (fixed and Wi-Fi) with over 60,000 active devices, a 19.2 Tb/s non-blocking switching fabric for a data centre with over 10,000 servers, 4,000 of which with 10Gb/s interfaces, and external connections including three trans-border 100 Gb/s circuits.
  • The Communication Engineering (CE) Section, responsible for designing, building and managing the Network infrastructure that supports the computing facilities and services of the laboratory as well as transferring the colossal volumes of LHC data to and from the data centre. The CE section is also responsible for critical network services such as DNS, DHCP and NTP.


As a Network Engineer in a small team of highly qualified colleagues, you will:

  • Participate in the operation and management of the Campus network, the Data Centre network and our long distance, high speed interconnections,
  • Contribute to the evaluation and deployment of new network services, and
