Process Integration Engineer
Overview
Founded in 2020 and based in 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. The company focuses on carbon nanotubes as the building blocks of quantum processors to reduce error rates, boost performance, and minimize hardware overhead. C12 has raised funding, published scientific papers, and holds several patents, with a fast-growing team across diverse nationalities and cutting-edge lab spaces in Paris.
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 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
About you
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
