SiPearl

SiPearl is a French semiconductor company designing high-performance, low-power microprocessors for the European exascale supercomputing initiative. Its flagship product, the Rhea processor, is built on Arm architecture and is intended to power the first generation of European exascale supercomputers, positioning SiPearl as a key player in Europe's push for technological sovereignty in high-performance computing (HPC). The company operates across Europe, with its headquarters in Maisons-Laffitte, France, and engineering teams in several countries, including Spain.

In Spain, SiPearl has an established R&D presence in Barcelona, where it contributes to processor design and software enablement. The company's work culture is deeply technical and collaborative, with a strong emphasis on innovation and European cooperation. For international professionals, SiPearl offers the opportunity to work on cutting-edge semiconductor technology within a mission-driven European context, with roles often requiring expertise in hardware architecture, embedded software, and HPC ecosystems. The Barcelona office provides a vibrant, international environment, making it an attractive option for engineers looking to contribute to a strategic European project.

SiPearl was founded in 2019 by Philippe Notton, a former ARM and STMicroelectronics executive, with the goal of designing a European microprocessor for exascale supercomputing. The company quickly gained backing from the European Processor Initiative (EPI) and secured significant funding to develop its Rhea processor. By 2023, SiPearl had expanded its engineering teams across Europe, including a key site in Barcelona, and continues to advance its roadmap for next-generation HPC chips.
