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.

YOUR RESPONSIBILITIES

As a Software Engineer specializing in software development, you will contribute to maintaining, developing, and optimizing tools for coordinating users, experiments, and activities across CERN’s test-beam areas and irradiation facilities. You will also work to harmonize and consolidate these tools to increase synergies, enhance data models, and reuse programming code and infrastructure.

RESPONSIBILITIES:

• Adapt and modify software tools based on input from facility and physics coordinators, ensuring seamless information flow between users, experts, and coordinators.
• Maintain and upgrade tools for irradiation facilities (Data Manager, online databases, DAQ & controls, gamma-spectrometry, e-logs) and collaborate with accelerator teams to develop operational pages using WRAP technology.
• Ensure long-term sustainability and integration of software tools with CERN’s IT services (e.g., single sign-on, databases, storage, backups).
• Manage deployment, availability, scalability, and reliable operation of IT services using CERN’s infrastructure.
• Support tasks such as organizing user meetings, scheduling beam times, and coordinating visits by international teams.
