Job Description
Introduction:
Work with us to evolve the CERN data storage systems used at the Large Hadron Collider (LHC) and at its international partners. CERN is the birthplace of the World Wide Web and one of the worlds leading laboratories for particle physics. Join the Storage and Data Management Group in CERNs IT Department as a Software Engineer for a unique challenge as the next step in your career. CERN take part!
The CERN IT Storage and Data Management group operates the core services used by both LHC and non-LHC experiments for data collection archival reconstruction analysis and global distribution via the Worldwide LHC Computing Grid.
You will join the Physics Data Services team responsible for delivering reliable data services to CERN and its scientific activities. CERNs storage systems are continuously evolving to meet the ever increasing needs of users and experiments both in terms of functionality and performance while also optimizing operational costs at CERN and its partner institutions. Today we deliver over 8 exabytes of data per year and manage more than 1 exabyte of disk storage.
As a Software Engineer for Distributed Storage you will contribute to develop and operate the next generation of storage solutions for high-energy physics experiments. Your work will focus on optimizing exabyte-scale storage infrastructure and refining the application stack for Grid Computing and HPC workloads. You will work with a variety of technologies including software-defined disk storage Linux-based disk server operations and large-scale data management for our multi-petabyte storage farms. Your role will involve designing developing and integrating next-generation storage services primarily leveraging technologies developed and operated by our group in collaboration with external partners.
