Your responsibilities

Are you a talented Software Engineer, passionate about developing web applications using state-of-the-art UX/UI technology? Do you enjoy designing scalable back-end systems for communication systems and working on several layers of the software stack? Work with us to develop and evolve CERN's advanced Network and Telecom infrastructure providing automation solutions for its effective management!

The Communication Systems (CS) Group is responsible for all aspects of network and telephony provision at CERN. We support a campus network (cabled and Wi-Fi) with over 50,000 connected devices, a 5Tb/s non-blocking switching fabric for a data centre with over 10,000 servers, more than 4,000 with 10Gb/s interfaces, and external connections including multiple trans-border 100Gb/s circuits. The CS group also operates its own VoIP telephony system, dedicated mobile telephony services (6500 subscriptions), a TETRA digital radio system (500 terminals) and a LoRaWAN network.

As a member of the Communication Tools (CT) Section in the CS Group, you will join a team of passionate Software Engineers in charge of the design, development and maintenance of the software suite used to model, configure, support and manage the CERN networks and telecom infrastructures.

Your main functions will include: 

• Maintain and further develop the IT/CS Web interfaces used by all CERN users to request network/telephony changes.
• Together with the other members of the team, participate in the design and development of new modules for the internal IT/CS network and telecom management framework, such as Technical Network firewall configuration automation/provisioning.
• Promote and develop DevOps processes and tools to further increase the automation and the quality of the produced software.
• Propose and implement changes in our database model and network APIs in order to support service integration solutions in the CERN data centres.
• Stay up to date on latest software technology trends.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
