Your role
We are looking to recruit a Cloud Systems Analyst to work as a member of the Cloud Systems team in support of activities in all aspects related to the evolution, release, and deployment of our on-premises OpenStack and Proxmox Cloud environments.
ECMWF provides high quality on-premises Cloud Computing services to its Member States and internal users by providing state-of-the‑art compute and object storage resources available in close proximity to the meteorological data archive and the existing HPC facilities.
The cloud services are based on two platforms, the Common Cloud Infrastructure (CCI) and the MCLOUD, both supported 24x7.
The CCI service consists of two OpenStack Clusters with approximately ten-thousand cores and two CEPH storage clusters of approximately six petabytes each. On these systems ECMWF runs a number of operational services such as the European Weather Cloud ( and the new version of the Copernicus Data Stores ( as well as many other internal and external projects.
The MCLOUD holds the virtual machines and processes that are critical to the delivery of our daily weather forecasts. The service is in the later stage of being migrated from vSphere to five Proxmox clusters.
Both platforms provide services for a growing number of AI ecosystems, like Anemoi, MLflow services, AIFS Assistant, and several Member States and internal AI workloads.
ECMWF is now looking for a qualified Cloud Systems Analyst to help support the Cloud platforms that power both services. ECMWF recognises that the role requires a broad skill set and offers training to help applicants develop any missing skills.
