Description 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 • Ph.D. in Computer Science, Computer Engineering, Electrical Engineering, or a closely related discipline. • At least 10 years of experience, after the Ph.D., in computer architecture, digital systems, and hardware-based system design. • Demonstrated experience in reconfigurable computing (FPGA) and specialized architectures for high-performance or application-specific systems. • Strong track record of participation in EU-funded or internationally funded research projects. • Strong publication record in high-impact international journals and conferences (e.g., IEEE). • Experience collaborating with multidisciplinary teams across academia, research institutes, and industry. • Ability to contribute to project coordination, technical leadership, and deliverable preparation. • Excellent communication skills in English (written and spoken). Desired qualifications Knowledge of and/or experience in and/or strong interest for: • Technology transfer, industrially-oriented research, or prototype validation for high-TRLs.
