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 http://home.cern.
Introduction
Join the team operating and evolving the cloud infrastructure service at CERN IT! The service provides the virtual and physical infrastructure underpinning the majority of IT and experiment services across multiple data centers.
As a Cloud and Network Services Engineer in the Compute and Devices (IT-CD) group, you will contribute to the efficient provisioning of compute resources to CERN users and experiments via CERN IT’s private cloud offering. Specifically, you will:
Join the team operating and evolving the OpenStack based private cloud service in CERN IT and contribute to secure compute resource delivery via virtual and physical machines to users, services, and experiments;
Drive the evolution of Software Defined Networking (SDN) across our two data centres to enhance the network related offerings for our user communities and to increase CERN’s security posture.
As a Cloud and Networking Services Engineer, you will join a passionate team, and take an important role in the management and evolution of CERN IT’s private cloud infrastructure deployment. You will have a full spectrum of responsibilities, from the administration, operation and maintenance of several thousand servers through to aiding users to interface with our service offering.
You will be involved in all aspects of system life cycle, including gathering user requirements, analysis of service Key Performance Indicators (KPIs) to help plan infrastructure design and evolution, and the development where necessary of system software such as monitoring, support services and configuration.
Functions
You will be responsible to oversee and drive the evolution of the cloud service in the area of Software Defined Networking, and maintain service offerings like load-balancing-as-a-service, private networks, or security groups for cloud and cloud-native applications.
In particular you will:
Be co-responsible for running the OpenStack based cloud deployment at CERN, ensuring appropriate operations and support to our communities;
Contribute to the design and development of “Software Defined Networking” components to address the needs of cloud and cloud-native applications and to strengthen the security posture of the infrastructure-as-a-service offering;
Engage and collaborate with the various CERN user communities throughout the organisation and the experiments, as well upstream developers and community members;
Provide user support, including analysing user requirements, providing advice on best practices, understanding usage patterns in order to plan for service improvements.
Master's degree or equivalent relevant experience in the field of Computer Science or a related field.
