The posting

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:

  • Getting familiar with the CVD setup, C12 processes and characterization equipment - e.g. SEM, EDX, AFM, mass spectrometer
  • Designing an experimental protocol to assess the influence of the Chemical Vapor Deposition (CVD) parameters on the growth of carbon nanotubes - e.g. geometry, density of catalyst nanoparticles, position in the furnace - and on the overall performances of the CVD
  • Collaborating with the characterization and nanofabrication teams to characterize the catalyst nanoparticles and to determine the properties of the grown carbon nanotubes

About You:

  • You are pursuing a Master’s degree in engineering, physics, chemistry or any related field and are looking for an end-of-studies internship
  • You love experimental lab work, have a problem-solving attitude - a previous experience in a lab / cleanroom is a plus
  • You are used to collecting, organizing and analyzing experimental data - programming skills are a plus (e.g. python)
  • You are result-oriented, organized and rigorous in your documentation
  • You can fluently communicate in English (verbal and written)
  • Experience in materials characterization techniques (e.g. SEM, EDX, AFM)
  • Experience with small electronics and mechanical parts

What we offer our interns:

  • €1,400
  • Two incredible office spaces in the heart of Paris (both next to the famous Panthéon!)
  • Swile meal vouchers
  • Vibrant office culture (team lunches, offsite events, Friday breakfasts..)
  • Mental health support with moka.care

You should join us if...

  • You want to contribute to achieving landmark results in quantum computing, making a difference in the emerging quantum technologies
  • You want to work within a 80+ people team with various backgrounds in nanofabrication, quantum electronics, and carbon nanotube science to create a revolutionary quantum computing processor
  • You want to thrive in an exceptional scientific environment with several industrial and academic partners
  • You share our values (excellence, scientific integrity, diversity, curiosity, and care) and want to help us define our product-focused culture and ambition to accelerate

C12 encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications, skills, knowledge and experience.

Applications from women are particularly encouraged and welcomed!

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
