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.

As part of the nanoassembly team at C12, you will help develop and operate the custom nano-assembly vacuum setup to transfer ultra-pure carbon nanotubes onto microchips in order to create qubits.

Key responsibilities:

Operate and continuously improve the nano-assembly vacuum setup

Design and validate experimental protocols to optimise the success rate of the nano-assembly (including mechanical, electrical and chemical processes).

Optically inspect, clean and characterize silicon chips (probe station, SEM...)

Work with the software team to improve the control software and the storage and analysis of your data in our internal database

Engineering diploma or Master’s degree in Electrical Engineering, Physics, Applied Physics, Materials Science or other related field; a PhD or one past work experience is also appreciated

You love experimental lab work

You have some experience in hardware and experimental setup design and fabrication

You like collecting, organising and analysing your data. Programming skills are a plus

You are detail-oriented and organized in your work and documentation style

You are diligent, independent, result-oriented and have a problem-solving attitude

Very good communication in English (verbal and written) is essential

Preferred Traits:

Experience in semiconductors

Experience with high vacuum systems

Experience in materials characterization techniques (SEM, TEM, AFM, probe station)

Experience in carbon nanotubes
