Technical Program Manager

• 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:

Program ownership and execution

• 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

Program planning and schedule management

• 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

Cross-team alignment

• 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

Reporting

• 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., * 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 budget/ Annual Learning & Development Allowance
• Sabbatical leave (after 2 years in the company)

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 minimises hardware overhead-key ingredients for scalable, fault-tolerant quantum computing. By crafting a unique approach that scales, we aim to revolutionise 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 60, including 20 PhDs, has over 20 nationalities represented. We have our own cutting-edge lab space 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.
