Job description

DESY

This project focuses on analysing and optimising scientific data flows in preparation for the High-Luminosity Large Hadron Collider (HL-LHC). It addresses the growing data management and processing demands of future LHC experiments by developing scalable strategies for efficient data access, distribution, and storage across distributed computing infrastructures. The central component of this project is dCache. dCache.org is an international collaboration of computer scientists providing open source software for storing and retrieving huge amounts of data distributed among a large number of heterogeneous server nodes, under a single virtual filesystem tree with a variety of standard access methods, including NFSv4.1 (pNFS), WebDAV and FTP protocols. dCache.org products are in use around the world by a large variety of scientific communities. The software is written in Java using a microservice-like architecture and based on widely adopted components, like Jetty, Spring, Zookeeper, Apache Kafka and others. The German section of dCache.org is part of DESY IT. DESY operates multiple instances of dCache providing more than 150 PiB of data and each is part of worldwide interconnected scientific communities with about 10 000 users. The successful candidate will design and evaluate data processing pipelines, contribute to the development of dCache, and collaborate closely with international research groups. This position offers an opportunity to work at the intersection of large-scale data systems, advanced computing technologies, and experimental particle physics – contributing directly to the success of next‑generation scientific discoveries at the HL‑LHC.

About your role

• Research and gap analysis between current and upcoming data and analysis workflows for the High–Luminosity LHC
• Collaboration with domain scientists from High Energy and Astro‑Particle Physics
• Development and prototyping of a distributed dCache across multiple German universities and High Performance Computing centres
• Development of extensions to the RESTful‑API to allow the LHC experiments to control the locality of data
• Analysis of the network topology and security between the distributed storage sites
• Perform large‑scale performance tests using scientific workloads with colleagues from LHC experiments at DESY and German remote sites
• Providing user support for the dCache software technology and DESY dCache customers

About you

• University master degree in computer science, physics, mathematics, or equivalent
• Excellent knowledge of working with Linux platforms
• Very good knowledge in Java and Python software development on Linux
• Good understanding of data analysis tools
• Good understanding of distributed and federated systems
• Experience with distributed computing and storage systems
• Good spoken and written command of the English language
• Team player with good communication skills
