❓ 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 2025, SiPearl completed the design of the most complex CPU ever designed in Europe, Rhea1, featuring 80 Arm Neoverse V1 cores and 61 billion transistors. The chip is currently in production at TSMC and will equip the first two European exascale supercomputers: 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, SiPearl employs almost 200 people in the following locations:
- France – Maisons‑Laffitte, Grenoble, Massy, Sophia Antipolis
- Spain – Barcelona
- Italy – Bologna

Following a €130 million Series A, the company has launched its Series B round.
Missions




The Security Protocol and Data Model (SPDM) protocol provides a standardised method for secure authentication, attestation, and key exchange between platform components. Although SPDM support is optional at the BMC M3 level, demonstrating compatibility will highlight SiPearl’s commitment to modern platform‑security standards.
The objective of this internship is to implement support for the SPDM protocol on the BMC and develop a client‑side testing tool to verify and validate the protocol implementation. This work may involve extending existing internal SiPearl tools and integrating with the OpenBMC ecosystem.
A secondary objective is to structure the testing tool so that it can be shared with the OpenBMC community as an open‑source validation utility promoted by SiPearl.
During This Internship, You Will
- Investigate the current status of Security Protocol and Data Model (SPDM) development within the OpenBMC community
