❓ About SiPearl… SiPearl is the European fabless designer of sovereign secure high-performance energy-efficient CPUs for HPC, AI and data centres. These CPUs will help address strategic challenges in the fields of security, defence, medical research, energy, climate and engineering with a reduced environmental footprint.
In June 25, SiPearl completed the design of the most complex CPU ever designed in Europe, Rhea1. Featuring 80 Arm Neoverse V1 cores, with 61 billion transistors, it is currently in production at TSMC. Sipearl CPUs will equip the two first European exascale supercomputers belonging to EuroHPC JU: Rhea1 will be integrated into the JUPITER machine based in Germany and Rhea2 will be part of Alice Recoque in France.

Following a €130 million Series A, the company has launched its Series B round.
💻 About The Role To validate our first tape-out, we developed an initial prototyping platform, using a smart hybrid approach, connecting a real hardware system development board (socket ready) with a small prototyping FPGA board. We also developed a full design emulation platform (Veloce/Siemens) to model the Silicon.
Our team is using those systems to prepare and test the full validation suit and be ready to deploy it when our silicon comes back.
We work closely with all levels of software (BMC, System Control, TFA, BIOS, Kernel) to ensure all firmware and software developed at SiPearl work seamlessly before reaching our customers.
Under the direction of the System Validation Team Leader or any other manager designated by Management, you will play a key role in ensuring the quality, reliability and compliance of the company’s software solutions.
You will be responsible for designing and executing comprehensive test strategies to identify defects, document anomalies and verify that software products fully meet user expectations, functional specifications and quality standards, while working closely with development and project teams.
