Job Description

Your responsibilities

Are you a talented DevOps Engineer who would like to come and help keep the services - that store, distribute, and analyse data generated by the Large Hadron Collider (LHC) - running ? The Worldwide LHC Computing Grid (WLCG) provides 1.4 million compute cores, 1.5 exabytes of storage from over 170 sites in 42 countries. This is distributed computing infrastructure on a global scale, and requires monitoring and full-stack testing in order to keep it running smoothly for the 12.000 physicists around the world who rely on it.

The Compute and Devices (CD) group in CERN IT provides a wide range of compute services, all the way from end user devices, through cloud infrastructure-as-a- Service, configuration management, batch and HPC computing at CERN, together with a set of services that support the whole WLCG.

As a member of the Compute and Configuration (CC) section of the CD group, you will join a team of engineers in charge of these services. We run the compute facility that comprises approximately 20% of the WLCG, using tools such as Puppet, OpenStack and Kubernetes to manage batch systems running HTCondor, HPC systems running SLURM, and the support services keeping everything glued together.

  • Running and helping to evolve and develop the web-based monitoring systems the "WLCG Experiments Test Framework (ETF)" and "HammerCloud" that are used to monitor and test grid sites around the world.
