Job description

Overview

Join to apply for the Security Engineer role at C12.

C12 develops quantum computers to solve highly complex computing tasks, currently out of reach of even the most powerful supercomputers. Building a quantum computer still needs innovators ready to tackle exciting challenges. C12's founders are convinced that only a new material for the qubit will bring a technological breakthrough. C12 uniquely uses carbon nanotubes as the fundamental building blocks of its quantum processor. This high-purity material minimises errors, radically improves performance and reduces hardware overhead for fault-tolerant computing. Combined with well-established semiconductor techniques, carbon nanotubes will help scale quantum computing, just as silicon revolutionised classical computing. Our unique & innovative quantum computing technology enables us to address use cases, solving intractable problems our industrial customers are facing.

Founded in 2020, C12 is a fast-growing start-up, that recently raised EUR 18 million in 2024 to further its research in its own lab in the heart of Paris (Panthéon).

Your role at C12 Quantum Electronics

As a Security (and Systems) Engineer, you will play a key role in protecting information systems while managing the internal IT infrastructure.

Your responsibilities will include:

• Assisting the Head of Software Development in evaluating and reporting on information system security (ISS) objectives
• Participating in compliance audits and responding to security questionnaires from clients and partners
• Performing risk analyses and overseeing penetration tests in coordination with the Head of Software Development
• Organising phishing awareness campaigns and conducting security training sessions
• Managing vulnerabilities and contributing to business continuity and disaster recovery plans (BCP/DRP)
• Participating in security crisis management and cybersecurity committee activities
• Updating and maintaining the information systems security repository
• Ensuring the proper functioning and security of internal infrastructure (networks, VPNs, remote access)
• Proposing and implementing solutions to optimise internal IT management
• Overseeing updates for internal systems and applications to ensure security and performance.

What we expect from you

• You have a degree in IT, Information Security, or a related field
• You have a minimum of 3 years of experience in information system security and IT management
• You are knowledgeable on ISO 27001/27002 standards and risk management practices
• You have experience managing internal IT infrastructure (IT equipment, networks)
• Security certifications (CISSP, CISM) or IT management certifications (ITIL, Microsoft, etc.) are a plus
• You have excellent problem-solving, communication and service-oriented skills
• You are fluent in English and French

Why join us

• You want to have a key role in a growing startup with challenges at the frontier of the 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 50-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.

At C12, a qubit, the fundamental functional unit of a quantum computer, is built from an isotopically ultra-pure 12C nanotube suspended above a silicon chip containing control electrodes and a quantum communication bus. Our spin qubits hold great promise in terms of individual control and manipulation as well as for the circuit architecture. A suspended isotopically-pure 12C nanotube holds great promise in terms of stability, as it reduces all sources of decoherence (charge noise, nuclear spin noise and phonon relaxation).

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.
