We seek one (1) R&D Engineer in Computer Science or Computer Engineering or Electrical Engineering. The candidate will participate in the R&D activities of FORTH in the context of the EuroHPC JU-funded project NET4EXA. The NET4EXA project aims to create an advanced interconnect, which will scale to tens of thousands of computing nodes and will support modern HPC systems that are designed for massive AI tasks, such as the training of Large Language Models. The interconnect forms the backbone of such systems, and their overall performance is intimately tied to the scalability of the network and its tight coupling with the high-end compute elements. Requirements • MSc Degree in Computer Science or Computer Engineering. • Experience in European Research Projects. • Physical presence at FORTH, Heraklion, Crete for the duration of the position. • Demonstrated familiarity with systems programming, e.g. with parallel or concurrent runtime systems. • Demonstrated familiarity with network simulation approaches and tools, e.g. the GNS3 Network simulator. • Demonstrated familiarity with open source monitoring suites, such as Grafana and Prometheus. • Fluent knowledge of English. • Names of at least three professional references.
