Jobbeschreibung

Join the team responsible for the High Throughput Compute systems at the heart of CERN’s data processing! Are you a recent graduate with an interest in large-scale computing, automation, and infrastructure technologies? Would you like to develop your skills while contributing to the evolution of the computing infrastructure supporting the High-Luminosity LHC?

As a member of the team responsible for the batch service and configuration management of IT services, you will have the opportunity to experience a varied role, from helping to automate the delivery of compute, to self healing infrastructure, to evolving the toolset that the IT department uses to manage its services.

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, machine-learning, Kubernetes, 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 focusing on services supporting the physics community. 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.

If you enjoy solving complex technical challenges, contributing to open-source software, and working with infrastructure at scale, come join us!
