Process Integration Engineer

Overview

Founded in 2020 and based in Paris, C12 Quantum Electronics focuses on developing a universal quantum computer built on carbon nanotube-based quantum processors. Our team of 80+ including 25 PhDs works in cutting-edge lab spaces in Paris to tackle challenging quantum hardware problems. The role offers a unique environment to grow, learn, and innovate as we advance from research to robust engineering processes that support future product generations.

We are seeking a Process Integration Engineer who will help transform C12's quantum hardware development from research workflows into repeatable and measurable engineering processes that enable validation, manufacturability, and industrialization for future generations of quantum hardware.

Responsibilities

• Own the maturation of the engineering processes supporting C12's quantum hardware roadmap, ensuring process capability evolves with technology and remains compatible with future hardware generations.
• Develop and maintain a deep understanding of end-to-end quantum hardware development processes, capturing knowledge, process flows, dependencies, assumptions, and risk factors.
• Collaborate with R&D and engineering teams to characterize processes, collect and analyze data, investigate failures, and 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 hardware generations.

Qualifications

• A MSc or PhD in Engineering, Physics, Materials Science, Nanotechnology, Semiconductor Processing, or a related technical field.
• Strong communication skills with the ability to build cross-disciplinary trust and influence technical decisions through data analysis and collaboration.
• Comfort working with emerging technologies where process understanding, measurement strategies, and engineering practices are still being developed.
• Experience in semiconductor process development, process integration, device fabrication, advanced assembly, or experimental hardware development.
• Experience defining process metrics, analyzing variability, improving yield or repeatability, and supporting root-cause investigations.
• Exposure to hardware characterization, test strategy, validation, reliability, or process qualification activities.
• Experience across nanotechnology, nanoassembly, quantum hardware, cryogenic systems, MEMS, photonics, or other complex hardware environments is a strong plus.
• Programming or scripting experience for data analysis, process monitoring or automation (e.g., Python or MATLAB) is a plus.

What we offer

• Salary: 55,000 – 62,000 euros yearly base
• Stock options for every employee (BSPCE/ESOP)
• Sponsored trips to conferences around the world
• A highly dynamic international team
• Swile meal vouchers
• Mental health support
• Training budget / annual Learning & Development allowance
• Sabbatical leave (after 2 years in the company)
• Vibrant office culture with two office spaces in the heart of Paris

You should join us if…

• You like hands-on work and technology
• You want to contribute to landmark results in quantum computing and make a difference in emerging quantum technologies
• You want to work within a team of 80+ people with diverse backgrounds in nanofabrication, quantum electronics, and carbon nanotube science
• You thrive in an exceptional scientific environment with industrial and academic partners
• You share our values of excellence, scientific integrity, diversity, curiosity, and care, and want to help shape our product-focused culture

We are an equal opportunity employer and welcome applicants from diverse backgrounds.
