Customer Delivery Manager

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 25 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 Customer Delivery Manager to initiate and drive complex commercial projects and to help define go-to-market pathways for our quantum computing technologies at C12. This role sits at the intersection of science, product, and market—requiring technical curiosity, project management skills and strong commercial instincts. You will work closely with research teams, customers and external partners to translate breakthrough technology into real-world applications. You will report directly to the Head of Sales and collaborate with Innovation and Partnerships, Product management, as well as the Theory & Applications and Software teams.
