Internship] Develop An In-chip Communication Library 2026 …, Castelldefels

**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.

Incubated within the European Processor Initiative (EPI) consortium and seed-funded by the European Union, SiPearl employs almost 200 people in:

- France (Maisons-Laffitte, Grenoble, Massy, Sophia Antipolis),
- Spain (Barcelona)
- and Italy (Bologna)

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

**Missions**: SiPearl is developing the processor dedicated to European supercomputers. In this context, you will join the verification team to ensure the functional correctness and robustness of processor IPs through advanced verification methodologies. Working closely with design engineers, you will contribute to the development and execution of verification environments based on industry standards.

In this internship you will:

- Develop **communication functions in embedded C (bare-metal, without an operating system)** for the verification team, enabling communication between verification processes running on different cores:

- Plan the **development phases** of the communication module
- Design and **document the communication mechanisms**
- Implement the **communication functions in C**
- **Test and validate** the communication between verification processes

**What makes you a good match for the role**:

- Student in the final year of an engineering school or pursuing a Master's degree in electronics, computer engineering, or a related field
- Knowledge of **embedded C programming**
- Understanding of **on-chip / inter-process communication mechanisms**
- Comfortable working in a **Linux environment (user level)**
- Familiarity with **Git for version control**
- Good **written and spoken English** for technical communication
