Are you a technician looking for a challenging professional experience to further your career? If so, joining CERN’s TTE programme may very well give you that challenge. This position as an Electrotechnician is part of our prestigious TTE programme.

The Electrical Engineering Group (EL) of the Engineering Department (EN) has the mandate to design, procure and operate CERN’s electrical power distribution networks. The CERN electrical network, supplied by 130 kV and 400 kV lines respectively from Switzerland and France, provides electrical power to a number of high-energy particle accelerators, large scale experimental areas, the Organization's computer centre and many office buildings on the various sites. The installed electrical power at the 18 kV level is rated at approximately 500 MVA.

The Network Operation Section (OP) is responsible for the operation of CERN's electrical distribution network: high and low voltage installations (400 kV, 66 kV, 20 kV, 18 kV, 3.3 kV, 400 V, 48V).


After a period of familiarization, as an electrotechnician in the Network Operation section, you will be responsible for the following operations associated with the procedures for the disconnection and isolation of high and low voltage equipment, and notably:


  • Prepare and carry out interventions on the high and low voltage electrical network, such as network reconfigurations, disconnection and isolation of equipment and making it safe, etc.;
  • Implement corrective measures (in the event of breakdowns or when safety or warning devices are triggered) and compile intervention reports and records;
  • Take delivery of new high-voltage and low-voltage systems; prepare and perform the associated commissioning tests;
  • Act as the technician responsible for the operations of one of the 10 areas of the CERN high and low-voltage electrical network;

Take part in the verification and follow-up of the conformity of contractors' activities and carry out inspections during interventions (maintenance contracts); issue certificates for work to be performed
