System Administrator (Storage and Virtualisation) - IT Service (AIT)
Kgs. Lyngby, Denmark
Job Description

The Research Solutions IT group at the Technical University of Denmark (DTU) is currently looking for a Linux administrator ideally with an academic background and experience with software development and teaching.

An important goal of our group is to enable tighter collaboration with relevant research departments at DTU, for example, to supervise student projects on contributions to open-source software we are using. While the main task of this position is administrating and maintaining our storage system, we are also setting up environments for students to experiment with open-source software and code changes. In the longer term we are planning to supervise Bachelor/Master projects and potentially develop courses about effective use of large-scale Storage-, HPC-, cloud- and data management systems, including contributions to relevant open-source projects in this area. This position will be part of paving the ground towards offering these services in the future.

About us
As part of our IT infrastructure for research at DTU we operate a ceph storage cluster and an opennebula private cloud instance. The storage cluster has a total raw capacity of 13PB distributed over 1000+ disk drives of different types. Our private cloud environment consists of 20 general access virtualisation servers and 10 project specific restricted access servers. The number of restricted access servers for research projects is expected to grow considerably in the future.

The ceph storage cluster provides software-defined storage to two major installations at Risø, the HPC cluster Sophia and our private cloud ONE. Besides maintaining these two production installations we plan to set up test clusters as a staging environment for updates, for our own developments and also for external ceph developers to debug problems and test patches on a physical test installation. A future goal is to offer bachelor- and master projects related to code development for ceph and opennebula using these test clusters.

About the position
You will be part of an efficient and well-functioning team of 20 IT specialists, who work purposefully and professionally to help research at DTU with good IT solutions. We emphasise a structured, methodical and conscientious approach to the tasks with a high degree of understanding of the users' needs.

• deploy and maintain test clusters
• develop, support and possibly supervise bachelor- and master projects (optional)
• develop and maintain our ansible automation playbooks
• develop and maintain our administration scripts
• documentation and user support

The position will include a period of education to get started. The length will depend on your initial experience with Linux and cluster administration.
