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 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 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 Quantum Electronics : As part of the Quantum Measurement team at C12, you will:
  • Perform experimental programs to optimize quantum operations on multi-qubit chips, driving improvements in control fidelity and system performance
  • Advance a physical understanding of spin qubits in carbon nanotubes integrated within high-impedance cQED platforms, working closely with the theory team to bridge experiment and modeling
  • Design, develop, and refine DC and microwave measurement setups and control software, emphasizing automation, calibration accuracy, and long-term experimental stability
  • Generate and maintain high-quality measurement datasets through rigorous analysis, thorough documentation, and reproducible experimental practices
About You:
  • A PhD in quantum physics, electrical engineering, or a closely related discipline
  • Deep understanding of quantum mechanics and experimental quantum systems
  • Hands-on experience with quantum hardware (qubits, cQED, quantum dots) is beneficial
  • Good coding skills in python and experience with data acquisition frameworks
  • Strategic thinker who connects experimental needs with engineering execution
  • Strong communication skills in English (oral and written)
What we offer:
  • Stock options for every employee (BSPCE/ESOP)
  • Two incredible office spaces in the heart of Paris (both next to the famous Panthéon)
  • Sponsored trip to conferences around the world
  • A highly dynamic international team
  • Swile meal vouchers
  • Vibrant office culture (team lunches, offsite events, Friday breakfasts..)
  • Mental health support with
  • Training budgets/ Annual Learning & Development Allowance
  • Sabbatical leave (after 2 years in the company)
You should join us if...
  • You like hands-on work technology
  • 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 60-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 welcomed. We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
