Description du poste

Founded in 2020 and based in the heart of Paris, C12’s mission is to be at the center of one of the biggest technological breakthroughs of the century, and change the course of history by building a universal quantum computer.

At C12, we believe that achieving a true breakthrough in quantum computing requires rethinking the fundamentals. That’s why our founders—deeply rooted in academic and engineering excellence—have chosen carbon nanotubes as the building blocks of our quantum processors. This ultra-pure material dramatically reduces error rates, boosts performance, and minimises hardware overhead—key ingredients for scalable, fault‑tolerant quantum computing. By crafting a unique approach that scales, we aim to revolutionise quantum computing just as silicon transformed classical computing.

Since our founding, we’ve raised over €25 million in funding, published 11 scientific papers, and secured 8 patents. Today, our fast‑growing team of 60, including 20 PhDs, has over 20 nationalities represented. We have our own cutting‑edge lab space in Paris' historic Panthéon district; where scientists, engineers, and innovators work side‑by‑side to tackle some of the most exciting technical challenges of our time.
