At CERN, the European Organisation 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.

Job description
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 Fabric & Communication Systems (FCS) 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 switches with 10Gb/s interfaces, and external connections including multiple trans-border 100Gb/s circuits.
The FCS 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 FCS 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 responsibilities
Contribute to the development of CERN's network automation tools, focusing on faster and more flexible IP address provisioning. A key task will be to work on live DHCP updates, allowing DHCP leases to be configured dynamically and enabling near-instant IP address allocation for users and services.
Extend IP Address Management support for Layer 2 interfaces, improving how network interfaces, devices and IP resources are modelled and managed. This work will involve back-end development, database modelling, API integration and collaboration with network engineers to deliver reliable features for CERN's production network.
Maintain and further develop the IT-FCS 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-FCS 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 centers.
Stay up to date on latest software technology trends.
Skills
Strong knowledge of Java (25), Spring Boot (4.1), REST, React (19).
Highly desired: SQL (Oracle and PL/SQL) and UX/UI design.
Spoken and written English, with a commitment to learn French.
Eligibility criteria:
You are a national of a CERN Member or Associate Member State.
By the application deadline, you have a maximum of two years of professional experience since graduation in Computer Science (Software Engineering) (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
You have never had a CERN fellow or graduate contract before.
Applicants without University degree are not eligible.
Applicants with a PhD are not eligible.
This position involves:
Stand-by duty, when required by the needs of the Organisation.
Work during nights, Sundays and official holidays, when required by the needs of the Organisation.
What we offer
A monthly net stipend of either 5,266 or 5,793 Swiss Francs per month depending on your degree.
30 days of paid leave per year plus 2 weeks' annual closure.
Coverage by CERN’s comprehensive health insurance scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
Family, child and infant monthly allowances depending on your individual circumstances.
A relocation package (installation grant and travel expenses) depending on your individual circumstances.
Possibility to extend your contract up to 36 months.
On-the-job and formal training including language classes.
We've signed the Gradcracker feedback pledge.
(This means that we will supply feedback if requested after an interview.)
