Purpose-driven work
Founded in 2019 with
the support of the European Union, SiPearl embodies Europe's dream of
mastering the technological heart of its supercomputers: the

Rhea, our first microprocessor currently under development, is being actively shaped by the entire SiPearl team. Once completed, it will be capable of processing massive volumes of sensitive data in a fraction of a second—essential for tackling today's scientific, industrial, and societal challenges, including artificial intelligence, healthcare, climate change, energy, engineering, geology, and defense.
This processor will thus play a key role in improving everyone's daily life.
Convinced that diversity within our teams is one of our greatest strengths, we are looking for talent with varied backgrounds, experiences, cultures, ages, and nationalities.
We are above all:
👨💻 passionate about microprocessor technologies (multicore architecture, ARM Neoverse V1 platform, 6nm lithography, etc.)...
...🚀 a deeptech company, in full growth...
...🧩 and motivated to invest in a strategic project for Europe, meaningful for the future.
