Software Engineer for Data Distribution

Your responsibilities

CERN's Storage and Data Management Group (IT-SD) is responsible for storing and enabling access to data for the Laboratory; and in particular for long-term archive, preservation and distribution of the LHC data to a worldwide scientific community. Today we deliver more than 5 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 manages more than 1 Exabyte of disk storage capacity in CERN's data center.

CERN's transfers and storage systems are being continuously evolved to adapt to changing user- and experiment needs in terms of functionality and performance; and to enable scaling at reduced operational costs at CERN and in its partner institutions.

You will join the Physics Data Services section and its core activities: storage operations, data distribution and data management.

As a Software Engineer for data distribution and storage, you will design, develop and integrate core transfers and storage services, primarily leveraging on the File Transfer Service (FTS) developed and operated by our group. 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 [http://home.cern.>

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
