Full Job Description
## Description 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 minimizes hardware overhead—key ingredients for scalable, fault-tolerant quantum computing. By crafting a unique approach that scales, we aim to revolutionize 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 80+, including 20 PhDs, has over 26 nationalities represented. We have our own cutting-edge lab spaces 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. If you're passionate about shaping the future of quantum technology and want to make a real impact, C12 offers a unique environment to grow, learn, and innovate. Role Overview We are looking for a Chief of Staff to support the CEO and Head of Operations in driving day-to-day execution across C12. This is a highly operational role focused on bringing structure, rigor, and velocity to the company, while scaling the organization and preserving our mindset. You will act as a force multiplier for the CEO and Head of Ops, ensuring that priorities are clear, key initiatives are delivered on time, and communication flows effectively across the organization. You will not be expected to define the strategy, but to make sure it is executed. ## Key Responsi
