Description du poste

Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum solutions. The company’s unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient quantum processing units that scale, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors.

With a team of more than 140 people, we develop our own hardware and software stack, from semiconductor quantum emitters and photonic processors to quantum control systems and quantum algorithms.

Our ambition is to build large-scale fault-tolerant quantum computers capable of solving problems beyond the reach of classical computation using Quandela's cutting-edge quantum dot technology.

Achieving this vision requires not only advances in photonic quantum computing, but also the development of scalable spin-photon interfaces, distributed entanglement capabilities and future SPOQC (Spin-Optical Quantum Computing) architectures that will enable modular and fault-tolerant quantum systems.

QUANTUM ROLE CONTEXT | Appended by Quantum.Jobs v2

Role context:

This role type exists to maintain internal technology architecture, identity systems, and operational connectivity within technical enterprises. Situated between executive leadership and operational business units, the function manages core hardware, networks, domain services, and enterprise software platforms across corporate sites and subsidiaries. By establishing security compliance, access controls, and data protection frameworks, professionals in this capacity ensure operational continuity, safeguard proprietary assets, and facilitate business process digital transformation across international operational units.

Quantum ecosystem relevance:

The role contributes to enabling infrastructure by providing secure operational environments for deeptech organizations. While not directly authoring quantum algorithms or designing hardware components, information technology management secures core networks, cloud infrastructure, and administrative tools supporting theoretical and experimental research. Standardizing identity security, endpoint protection, and software integration across operations protects critical research data and ensures reliable administrative functionality needed to scale enterprise quantum technology operations across regions.

Capability signals:

• - Strategic alignment of corporate information technology infrastructure across international subsidiary operations
• - Implementation of enterprise cybersecurity frameworks, identity controls, and zero-trust network architectures
• - Administration of cloud service environments, virtual platforms, and continuous monitoring systems
