Your role at C12 Quantum Electronics
- As a Systems Engineer, MBSE at C12, reporting directly to the Head of Engineering, you will play a central role in bridging fundamental research and industrial-grade engineering. You will work in central Paris at the intersection of theoretical physics and large-scale hardware development, collaborating closely with physicists, engineers, software and product teams. Your mission is to shape, structure, and guide complex quantum hardware systems from early research concepts through to validated, scalable architectures, ensuring that cutting-edge science is translated into robust and manufacturable solutions. Your key responsibilities will include:
- Owning the MBSE system model as the source of truth, including governance for model quality, traceability, and change control.
- Defining and maintaining a system-level perspective, ensuring alignment with scientific,
- Defining modelling conventions, abstraction levels, and acceptance criteria for model contributions.
- Ensuring bidirectional traceability between requirements, architecture, analysis, and verification evidence
- Embracing a unique opportunity to pioneer systems engineering methods in quantum computing, developing practices in largely uncharted territory
- Working closely with product, design, software, R&D, partnerships, and supply teams to define, refine, and document system and subsystem requirements
- Owning the technical decision record at system level, ensuring decisions are consistent with models, experimental data, and approved assumptions
- Contributing to the definition of the hardware architecture roadmap across fabrication, testing, integration, validation and scalability
- Supporting informed make-or-buy decisions with partners and suppliers
- Providing impact analysis for proposed changes, and ensure changes follow agreed review and approval paths
- Leading system-level trade studies with explicit criteria, quantified assumptions, and documented decisions, including rationale, risks and follow-up actions.
- Supporting the design and specification of quantum computer systems, identifying key system bottlenecks, technological barriers to industrialisation, and trade-offs.
- Collaborating with physicists to review technical papers and research results, translating scientific insights into system trade studies and initial performance requirements.
- Ensuring research concepts are evaluated against manufacturability and lifecycle constraints at an early stage
- Staying current with advances in quantum computing, quantum error correction, and quantum applications.
About you:
- You have a master’s degree in Engineering, Physics, or a related field
- You have 8+ years of experience in systems engineering within engineering-intensive industries such as aerospace, automotive, nuclear, or equivalent
- You have strong rigor and discipline in system definition, analysis, validation and documentation.
- You have proven experience taking complex hardware systems from early concept through integration, validation, and iteration under technical uncertainty.
- You have proven experience with Model Based Systems Engineering, including hands-on experience with MBSE platforms, system modeling, simulation, and analysis tools.
- You have a solid background or understanding of physics, with the ability to engage deeply with scientific concepts and research.
- You are to operate in environments with incomplete data, evolving requirements, and high technical risk

What We Do
C12 is building reliable quantum computers.
The company is a spin-off from ENS launched in January 2020 by twin brothers Matthieu and Pierre Desjardins to supercharge the development of the lab’s promising new quantum technology.
Quantum computing has the potential to change our lives. But frequent errors limit the technology’s viability. We are tackling the fundamental issue: the nature of the hardware itself. We are tapping into the simplest material–carbon–to drive a technological breakthrough in the field. Unlike other quantum computers, we use carbon nanotubes as the fundamental building block of our processor. By combining the power of an ultra-pure material with an easy-to-manufacture semiconductor device, we are building a scalable platform for quantum computing.
Our executive co-founders bring a unique combination of scientific excellence and business skills to the company. Our team is made up of the world’s most accomplished experts in quantum electronics and carbon nanotube science. Our scientific advisors are renowned scientists and pioneers in spin qubits: Dr. Takis Kontos, Dr. Matthieu Delbecq and Dr. Jérémie Viennot.
In June 2021, C12 secured a $10 million seed round with funding from 360 Capital, Bpifrance (Digital Venture Fund), Airbus Ventures, BNP Paribas Développement, and Octave Klaba (OVHcloud), and additional grants from Bpifrance and the Ile-de-France Region.
We are leading quantum’s next material breakthrough, and we are just getting started. Silicon enabled the emergence of classical computing – it’s time for carbon to do the same for quantum !
