Job Summary
Founded in 2020 and based in the heart of Paris C12s 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. Thats why our foundersdeeply rooted in academic and engineering excellencehave chosen carbon nanotubes as the building blocks of our quantum processors. This ultra-pure material dramatically reduces error rates boosts performance and minimizes hardware overheadkey 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 weve 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 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 youre 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 Quantum Electronics :
As a Cleanroom Engineer at C12 you will be responsible for the specification installation operation maintenance and continuous improvement of cleanroom process equipment.
