Distributed Storage Engineer (IT-SD-GSS-2026-96-LD)

At CERN, the European Organization for Nuclear Research, the Distributed Storage Engineer role involves working on the evolution and operation of large-scale, distributed storage systems. These systems are crucial for the data storage and management needs of the Large Hadron Collider (LHC) and other experiments. CERN is renowned for its groundbreaking research in particle physics and the birthplace of the World Wide Web. The main day-to-day responsibilities include managing and operating distributed disk storage, block, object, and filesystem services using open-source technologies like Ceph. This involves troubleshooting and maintaining these systems across multiple data centers, ensuring high availability and performance. The role also includes contributing to the architecture and design of storage services, as well as participating in change management, incident response, and user support. Additionally, the engineer will liaise with stakeholders both within and outside the IT department. To qualify for this role, candidates must have a Master's degree or equivalent experience in Computer Science or a related field. Essential requirements include a deep understanding of Linux operating systems, distributed storage architectures, and experience in C++ software development, particularly with Ceph. Strong collaboration and communication skills are also crucial for working effectively with cross-functional teams and partners. Proficiency in spoken and written English is required, with a commitment to learning French. Nice-to-have skills include knowledge of scripting languages like Python and shell, as well as competencies in the design and development of storage systems. The role offers opportunities to work on inspiring projects and new technologies, such as storage for HPC and AI/ML. The position is based at CERN, which values diversity and inclusivity, and offers a hybrid work environment with flexible hours. The role may involve working nights, Sundays, and official holidays, as well as standby duty when required. What the role asks for: - Master's degree or equivalent experience in Computer Science or a related field. - Deep understanding of Linux operating system performance, tuning and administration. - Deep understanding of architecture of distributed storage and filesystems (e.g. NFS, CephFS). - Demonstrated experience in C++ software development of distributed storage systems. - Strong collaboration and communication skills. - Proficiency in spoken and written English. - Commitment to learn French.
