Computing Fellowship in Distributed Computing Infrastructure Engineering


Company Description

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

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.


Job Description

At the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC), we process 24/7 proton and ions collisions on more than 300 thousands cpu cores spread over more than 50 computing centres world wide.

You will be part of a small and dynamic devops team of engineers and physicists at CERN, in the CMS experiment. Some of the technologies we use are the HTCondor batch system software, High Throughput Computing, heterogeneous platforms, the Python programming language and the Puppet configuration management. We are also working with Cloud and HPC facilities, too.

You will.

  • Monitor, maintain, and help to evolve the software layer that allows CMS to submit its data processing and analysis jobs world wide;
  • Interact directly with the development communities of the software packages at the core of our stack, GlideinWMS and HTCondor, as well as any software packages we may adopt in the future;
  • Provide essential feedback to the developers, inherent to the success of the software projects, through our testing, integration, and prioritization of new features of their product.



Eligibility criteria

  • You are a national of a CERN Member or Associate Member State;
  • You have a Bachelor or Master’s degree in Computer Science, Engineering or other related field;
  • You have no more than 4 years’ experience after completing your highest diploma.

Essential skills and experience

  • Professional experience with Linux service administration and management;
  • Professional experience with Python and Shell scripting;
  • Knowledge of the basics of the functioning of a batch system.

Desired skills and experience

  • Experience with distributed computing or HPC;
  • Experience with high throughput computing on Grid/Cloud;
  • Experience with Puppet (or similar configuration management);
  • Experience with software development and code design.

Please note that CERN Staff members are not eligible to apply for a Fellowship.
