Operations & Reliability 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.

Your role at C12

C12 builds quantum computers in-house in Paris, on a unique carbon-nanotube qubit platform. As we scale, our lab is becoming a real production facility: cleanrooms, industrial fabrication tools, dilution refrigerators, gas and cryogenic systems that must run reliably every day.

We are looking for an Operations & Reliability Manager to build and lead the team that keeps this facility available, reliable and ready to scale. You will own how we run operations day to day and how we make them progressively more robust: preventive maintenance, monitoring and data, resilience, and the operational readiness of our current and future facilities. You will build and grow a team of technicians and, over time, an on-call and shift coverage team, own the facility operations budget, and work hand in hand with Production, R&D, Qubit Control and Software.

This role reports to the R&D Operations lead.
