Lead AI Engineer (Quantum Systems) Ajouter aux favoris

Founded in 2020 and based in the heart of Paris, C12's 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. That's why our founders-deeply rooted in academic and engineering excellence-have chosen carbon nanotubes as the building blocks of our quantum processors. This ultra-pure material dramatically reduces error rates, boosts performance, and minimizes hardware overhead-key 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, we've raised over €25 million in funding, published 11 scientific papers, and secured 8 patents. Today, our fast-growing team of 75, including 20 PhDs, has over 26 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 you're 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.

This role prioritizes AI initiatives across qubit calibration and control, quantum error correction, manufacturing, and quantum chip design. You will ensure AI efforts are tightly aligned with C12's core quantum roadmap.

Key Responsibilities:

• Refine and own the AI4quantum roadmap aligned with C12's quantum hardware and system roadmap
• Lead the design and application of AI and algorithmic methods in collaboration with quantum physicists for qubit calibration, qubit control optimization, quantum error correction, and system level performance improvement
• Partner with data engineering to build and scale pipelines for quantum hardware and manufacturing data
• Define AI-specific requirements for data quality, labeling, curation, and synthetic data generation to enable robust model training and analysis
• Collaborate closely with quantum hardware engineers and software teams to integrate AI solutions into production workflows
• Influence prioritization within existing software and data teams to ensure AI critical projects are executed effectively
• Provide technical expertise and guidance on AI and algorithmic approaches to teams across C12, while laying the groundwork for future team expansion

About You:

• Ph.D. in computer science, mathematics, artificial intelligence or related
• Strong background in AI, machine learning, or applied mathematics with a clear interest in quantum technologies
• Solid understanding of linear algebra
• Able to operate across research and engineering
• Collaborative mindset
• Clear communicator
• Fluency in the English language

Preferred experience :

• Experience applying AI or advanced algorithms to hardware intensive or physics driven domains
• Exposure to quantum computing concepts (especially qubit control)
• Hands on experience with data engineering, large scale data pipelines, or scientific data management
• Familiarity with production environments

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 trip to conferences around the world
• A highly dynamic international team
• Swile meal vouchers
• Vibrant office culture (team lunches, offsite events, Friday breakfasts..)
• Mental health support with moka.care
• Training budgets/ 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
