Founded in 2020 and based in the heart of Paris C12s 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. Thats why our foundersdeeply rooted in academic and engineering excellencehave chosen carbon nanotubes as the building blocks of our quantum processors. This ultra-pure material dramatically reduces error rates boosts performance and minimizes hardware overheadkey 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 weve raised over 25 million in funding published 11 scientific papers and secured 8 patents. Today our fast-growing team of 60 including 20 PhDs has over 20 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 youre 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 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:
Systems engineering leadership
- 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
Cross-functional integration documentation and decision support
- 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
Research driven architecture and trade studies
- 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 masters 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 offer:
- Stock options for every employee (BSPCE/ESOP)
- Two incredible office spaces in the heart of Paris (both next to the famous Panthéon!)
- Sponsored tripto conferences around the world
- A highly dynamicinternational team
- Swile meal vouchers
- Vibrant office culture (team lunches offsite events Friday breakfasts..)
- Mental health support with
- Training budget/ Annual Learning & Development Allowance
- Sabbatical leave (after 2 years in the company)
You should join us if...
You want to contribute to achieving landmark results in quantum computing making a difference in the emerging quantum technologies
You want to work within a 60-people team with various backgrounds in nanofabrication quantum electronics and carbon nanotube science to create a revolutionary quantum computing processor
You want to thrive in an exceptional scientific environment with several industrial and academic partners
You share our values (excellence scientific integrity diversity curiosity and care) and want to help us define our product-focused culture and ambition to accelerate.
C12 encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications skills knowledge and experience. Applications from women are particularly welcomed.
We may use artificial intelligence (AI) tools to support parts of the hiring process such as reviewing applications analyzing resumes or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
