Your role at C12 Quantum Electronics
- As a Technical Program Manager at C12, directly reporting to the Head of Engineering, you will lead programs to deliver highly complex quantum computers under ambitious technical and schedule constraints. You will operate in central Paris at the intersection of engineering execution, operations and leadership alignment, ensuring that advanced R&D efforts translate into delivered hardware. Your responsibilities will include:
- Owning the end-to-end delivery of quantum computer systems
- Defining, planning, and executing complex technical programs spanning systems, hardware, electronics, software, and operations.
- Leading release governance: planning, scope lock, change management, and release decision meetings
- Ensuring manufacturing, test, and quality plans are aligned to the release schedule
- Driving external dependency management with key vendors and partners, including contingency plans
- Establishing and managing detailed schedules, including critical path
- Running program cadence, including quantum chip fabrication
- Defining release milestones, entry and exit criteria, and readiness gates
- Coordinating integration across subsystems, ensuring interface closure, availability of test infrastructure, and availability of integration environments
- Acting as the central integration point among engineering teams, R&D teams, operations,
- Partnering with Systems Engineering to ensure requirements and specs are clear, traceable, and testable, and that change control is respected.
- Ensuring R&D time is focused on high-leverage technical work, minimizing diversion to operational tasks.
- Maintaining and actively managing the program risk register, identifying risks early and driving mitigation plans with accountable owners
- Maintaining program documentation including system plans, decision tracking register, and post-mortems to capture and share learnings.
- Providing concise, transparent program updates to leadership through regular dashboards and reviews.
About you:
- A master's degree in Engineering, Physics, or a related technical discipline
- You have 5+ years of experience in technical program or project management within complex hardware or hardware-software environments
- You have a proven track record of leading technical programs, identifying critical paths, and driving on-time delivery
- You have a strong understanding of hardware development lifecycles such as semiconductor, electronics, or complex system development
- You have excellent organisational, analytical, and problem-solving skills, with strong attention to detail and the ability to manage multiple priorities
- You are hands-on, driven, resilient, and collaborative mindset.

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 !
