Computing Fellowship: Full Stack Web Developer for the ALICE Experiment


The ALICE experiment is finalizing a major upgrade and will restart its operations in 2022. A key element of this upgrade is a new computing system in order to handle a data volume roughly 100 times larger than during the previous operational period.

As part of the upgrade, a brand new web-based system is being developed to provide the ALICE collaboration centralized access to all metadata related to scientific and operational activities, produce reports for operational teams and management and globally support the ALICE data taking activities in the experimental site.

As a member of a small and dynamic team working in the CERN Experimental Physics department, you will :

  • Contribute to the development and operation of this new system;
  • Design, develop, and deploy new features that enable and make it easier for researchers and managers to retrieve;
  • Verify and access the data they need;
  • Work with relational databases and modern web technologies such as NodeJS, ES6 Javascript, web components, virtual DOM and autoredraw.

There are many challenges and opportunities awaiting which will make you grow personally and professionally!

Hvem er CERN?

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
