Job Details

Software Engineer for Data Distribution (IT-SD-PDS-2023-140-GRAP)

  • Geneva, Switzerland Full-time

Job Description

Your responsibilities

CERN's Storage and Data Management Group (IT-SD) is responsible for enabling data access for the laboratory and most notably for long-term archive, preservation and distribution of the LHC data to a worldwide scientific community. Today we deliver more than 4 Exabyte of data per year, we orchestrate yearly more than 1 Exabyte of data across the Worldwide LHC Computing Grid (WLCG) with the File Transfer Service (FTS) and we operate a heterogeneous disk/tape system, with several large disk farms. In total the group handles more than 1 Exabyte of raw disk storage.

CERN's storage systems are continuously evolved to adapt to changing users' and experiments' needs with respect to functionality and performance and to further reduce their operational costs at CERN and in its partner institutions.

You will join the activities of the Physics Data Services section: Storage operations, data distribution and data management. As a Software Engineer for data distribution and storage, in the context of the European Project "EOSC Beyond", you will design, develop and integrate core transfers and storage services, primarily leveraging on the File Transfer Service (FTS) developed and operated by the group. This enhanced FTS service will be used to integrate the Core Execution Framework and enhance the composability and interoperability of cross-domain data, services and tools. You will also be involved in storage and data services development and operations in a larger team, as required by the work programme.

In addition you will maintain and improve service documentation (procedures, regular reports, incident analysis and user documentation) and contribute actively to the evolution of the CERN data management and transfer services.

About us

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
