[Permanent position] Benchmark Cloud & HPC engineer
Company Overview
SiPearl is the European fabless designer of sovereign secure high-performance energy-efficient CPUs for HPC, AI, and data centres. These CPUs address strategic challenges in security, defence, medical research, energy, climate, and engineering while reducing environmental footprint.
In June 2025, we completed the design of the most complex CPU ever designed in Europe, Rhea1, featuring 80 Arm Neoverse V1 cores and 61 billion transistors, now in production at TSMC. Rhea1 will be integrated into the EuroHPC JU exascale supercomputer JUPITER, and Rhea2 will be part of Alice Recoque.
Incubated within the European Processor Initiative (EPI) Consortium and seed-funded by the European Union, we employ almost 200 people in France (Maisons-Laffitte, Grenoble, Massy, Sophia Antipolis), Spain (Barcelona), and Italy (Bologna). Following a €130 million Series A, we launched a Series B round.
