Computing Fellowship/Software Developer


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 organisation.


Job Description

The Worldwide LHC Computing Grid (WLCG) project is a global collaboration of around 170 
computing centres in more than 40 countries, linking up national and international grid 
infrastructures. The WLCG Operations and Experiment Liaison team coordinates WLCG 
operations and contributes to complex tasks such as infrastructure optimization and the effective integration of the infrastructure and the computing systems of the scientific user communities. 

Members of the team work closely with the science users and technology experts to ensure 
strong collaboration between the computing experts across user communities, WLCG project and CERN IT.

The successful candidate will work on WLCG operations tools namely on consolidation of the monitoring data of the LHC experiments enabling these data on the common monitoring 
infrastructure and therefore  will build expertise in open source data analytics technologies widely adopted in large communities and industry. He/she will also  acquire experience with data science and analysis technique and methodologies. 

Key responsibilities: 

  • Contribute to the development of the new solutions aiming to reduce WLCG operational costs and automate operational tasks, optimize utility of WLCG resources and improve science productivity;
  • Encourage common solutions and adoption of the new technologies. This includes enabling experiment-specific monitoring data on the common CERN monitoring infrastructure (MONIT).



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 

  • Experience in object-oriented software design in the Linux environment with Python;
  • Experience with data analytic and monitoring tools (ElasticSearch, Hadoop/Spark, Kibana, Grafana);
  • DevOps experience: usage of CI/CD tools, test automation and deployment.

Professional experience in one or more of the following would be an asset:

  • Virtualisation, configuration and container technologies (Openstack, Puppet, Docker, Kubernetes)
  • Experience of work in the computing projects of the LHC experiments;
