HSE Unit Computing Support 

Safety computing opportunities at the heart of CERN's operations

Work on the essential safety computing projects which keep people and the environment safe at the heart of the world’s biggest particle physics collaboration!

Who we are:

The Computing Support section, as part of the Transversal services group, is responsible for the development and maintenance of safety software solutions, used by thousands of users at CERN.

We provide a large set of software for CERN:

  • REMUS: A Supervisory Control and Data Acquisition (SCADA) software, that controls thousands of pieces of electronics, acquiring 80 billion measurement data points every year.
    Technologies: Siemens WinCC OA, C++, Oracle RDB, Apache Kafka
  • REMUS Web: A web-based data analytics application.
    Technologies: Java, Spring boot, React, WebSocket, Highcharts, Oracle RDB, InfluxDB, Apache Kafka
  • SAILOR Software suite: A web-based application for the management of safety inspections and the resolution of non-conformities. 
    Technologies: Java, Spring boot, React, Highcharts, Oracle RDB
  • CERES: A web-based application for the inventory of chemical risk and risk assessment. 
    Technologies: Java, Spring boot, React, Oracle RDB
  • Dosimetry: A web-based application for the management of personal dosimeters and radiation doses. 
    Technologies: Java, Spring boot, React, Oracle RDB
  • RAISIN: A web-based application for the management radiation areas and radiological risk integrated with the CERN geographical information system. 
    Technologies: Java, Spring boot, React, Oracle RDB

Open Roles:

There are currently no open roles in the section, however opportunities for students, graduates and professionals in computing arise regularly to take part in the exciting projects in the section's remit. So watch this space for future openings!

At all times, you can consult all open roles at CERN on the CERN Careers website.

Do I need to know about particle physics to work at CERN?
Absolutely not! In fact, only a very small number of CERN’s workforce are physicists. You will be working on electronics projects in a multi-skilled and supportive team.

Do I need to speak French or English?
CERN's working languages are English and French, English is required for this role. French is an advantage but is not required and you will have the opportunity to learn as you go.
