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 close to 40 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 :
To support our growing experimental and fabrication activities we are looking for a Lab Technician to help ensure smooth safe and reliable day-to-day lab operations. As a Lab Technician at C12 you will support experimental characterization and fabrication-related activities by maintaining laboratory infrastructure preparing experiments managing consumables and ensuring compliance with safety and quality standards. You will work closely with engineers researchers and the nanofabrication team to keep the labs running efficiently in a fast-paced startup environment.
This role is ideal for someone hands-on organized and eager to work close to cutting-edge quantum technology.
Key Responsibilities:
- Support daily laboratory operations across R&D labs
- Prepare experiments and workstations (equipment setup sample handling basic measurements)
- Maintain laboratory equipment:
Routine checks basic maintenance and troubleshooting
Coordination with internal teams or external service providers when needed
- Manage lab consumables and spare parts:
Inventory tracking ordering and storage
- Ensure proper labeling documentation and organization of samples and lab spaces
Required Qualifications:
- Technical degree (BTS DUT Bachelors or equivalent) in physics electronics materials science chemistry or a related field
- Hands-on experience in a technical environment
- Comfortable in restrictive contamination free environments for extended periods of time.
- Strong attention to detail and organizational skills
- Comfortable working in a multidisciplinary fast-moving startup environment
- Working proficiency in English
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 budgets/ Annual Learning & Development Allowance
- Sabbatical leave (after 2 years in the company)
You should join us if...
You like hands-on work and technology
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.
