Description du poste

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 25 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.

C12 is building breakthrough quantum technologies through a unique combination of scientific excellence, engineering innovation and ambitious execution. As we grow, we are creating a new generation of managers across the company. Helping these managers succeed is critical to our ability to scale our teams, develop our talent and preserve the culture that makes C12 unique. We are looking for a Senior People Partner to work closely with managers across the organisation. You will help them navigate people challenges, develop their leadership capabilities, build high‑performing teams and make thoughtful talent decisions.

Additionally, you will collaborate closely with the People Operations team on essential HR processes and enhance management and leadership skills throughout C12. You will be a trusted advisor to managers, a close partner to our Head of Operations (in charge of People), and a key contributor to the evolution of our organisation as we grow.

Responsibilities

• Building trusted relationships and collaborate: establishing strong, trusted relationships with managers throughout the organisation and work alongside the People Operations team to support them across the entire People cycle, including recruitment, onboarding, performance management, development, internal mobility, and offboarding.
• Coaching and guidance: providing coaching for managers in navigating day‑to‑day leadership challenges and complex people issues, while also supporting them in difficult conversations, performance management, and enhancing team dynamics.
• Employee engagement and talent management: advising managers on strategies for employee engagement, motivation, and retention; while helping to identify capability gaps and future talent needs within their teams.
• Supporting organisational change and communication: assisting in team evolution and organisational changes as needed, ensuring effective communication flows between managers, the People team, and company leadership.
• Cultivating management excellence at C12: contributing to defining and scaling great management practices at C12 by helping to establish management principles and expectations, designing and continuously improving manager onboarding experiences, and developing practical tools, frameworks, and resources for managers.
• Enhancing training and development: organising and coordinating management training, coaching, and development initiatives to foster consistency and fairness in management practices across teams, while building communities of practice among managers to share insights and best practices.
• Committing to continuous improvement: gathering feedback from managers and teams to refine our People practices, creating systems, habits, and capabilities that enable effective management at scale.
• Collaborating with the Head of Operations on people matters: acting as a liaison between managers, employees, the People team, and the Head of Operations by assisting in the preparation for the performance review calibration and promotion committee, surfacing emerging people challenges and organisational risks, and providing insights on engagement, team dynamics, and retention concerns. Additionally, you will support the deployment and adoption of people initiatives while acting as a steward of C12’s culture and values across the organisation.
