OtherIntegration Engineer

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 a Process Integration Engineer, you will play a central role in transforming C12's quantum hardware development from research-driven workflows into robust, measurable and repeatable engineering processes capable of supporting future product generations.

Working across R&D and engineering teams, you will identify the factors driving performance and variability, define meaningful process metrics, drive process improvements and establish the foundations required for future validation, manufacturability and industrialization.

This role sits at the frontier between research and engineering, where process understanding, measurement strategy, and engineering rigor become critical enablers of future quantum hardware products.

Key responsibilities:

Own the maturation of the engineering processes supporting C12's quantum hardware roadmap, ensuring that process capability evolves alongside the technology itself and remains compatible with future generations of quantum hardware

Develop and maintain a deep understanding of C12's end-to-end quantum hardware development processes, capturing critical knowledge, process flows, dependencies, assumptions and risk factors

Work directly with R&D and engineering teams to characterize processes, collect and analyze data, investigate failures, drive process improvements across fabrication, assembly, integration and characterization activities

Ensure process assumptions, dependencies, risks, and maturity gaps are visible and integrated into engineering and program decisions

Identify process limitations, scalability bottlenecks, and opportunities for standardization, automation, process control, and future industrialization. Evaluate which processes should be strengthened, adapted, or reimagined to support future generations of quantum hardware

You have a MSc or PhD in Engineering, Physics, Materials Science, Nanotechnology, Semiconductor Processing, or a related technical field

You are a strong communicator, able to build trust across disciplines and influence technical decisions through data analysis and collaboration.

You are comfortable working with emerging technologies where process understanding, measurement strategies and engineering practices are still being developed

You have experience in semiconductor process development, process integration, device fabrication, advanced assembly or experimental hardware development

You have experience defining process metrics, analyzing variability, improving yield or repeatability, and supporting root-cause investigations

You have exposure to hardware characterization, test strategy, validation, reliability or process qualification activities.

Experience across several of the following fields is a strong plus: nanotechnology, nanoassembly, quantum hardware, cryogenic systems, MEMS, photonics, advanced instrumentation or other complex hardware environments

Programming or scripting experience for data analysis, process monitoring or automation such as Python or Matlab, is a plus
