About Si Pearl Si Pearl 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 2025, Si Pearl 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. Si Pearl CPUs will equip the two first European exascale supercomputers belonging to Euro HPC JU: Rhea1 will be integrated into the JUPITER machine based in Germany and Rhea2 will be part of Alice Recoque in France. Incubated within the European Processor Initiative (EPI) Consortium and seed‑funded by the European Union, Si Pearl employs almost 200 people: France (Maisons‑Laffitte, Grenoble, Massy, Sophia Antipolis) Spain (Barcelona) Italy (Bologna) 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 suite 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 Si Pearl 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.

Your Missions

Define and maintain test strategies and test plans aligned with functional and technical specifications. Design, develop and maintain manual and automated test cases and scripts. Ensure that all FW/SW stacks are integrated properly and meet the system requirements.

Execute functional, non‑regression and performance tests, analyze results and track defects. Work closely with development and project teams to investigate issues and improve product quality. Communicate test results, risks and quality indicators to stakeholders.

Contribute to the continuous improvement of testing processes and tools. Supervise and mentor interns, contributing to topic definition and recruitment‑related activities.
