Your responsibilities

The Engineering (EN) Department's Information Management (IM) group is looking for a highly motivated full-stack software engineer with great technical skills and a genuine interest in learning new things. You will join a young and international development team inside the PLM (Product Lifecycle Management) section, whose mission is to provide engineering information management capabilities for the entire accelerator complex and its detectors. This includes notably the management of millions of engineering documents, product definitions as well as CAD (Computer Aided Design) models.

We are currently in a challenging project of modernizing and simplifying the existing landscape of heterogenous applications and allowing the Organization to move forward towards engineering Digital Twins. In total, over 5000 users depend on the software provided by the group.

In your work, you will for example:

• Implement backend applications using Java or .NET.
• Build web applications using modern technologies (React/Electron/Typescript).
• Integrate 3D model visualization technologies: web and native viewers, virtual/augmented reality.
• Perform code reviews, testing, delivery and support of the software.
• Carry out data analysis and data migrations.
• Be part of a project delivering engineering Digital Twins of CERN installations.

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.
