IT & Information Sytems Manager in Massy

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.

Join Us at the Forefront of Quantum Computing Innovation

You will be leading the team in charge of Quandela's foundational IT systems (identities, devices, network, common applications) across the Group.

You will lead a four-person team and take ownership of Quandela's internal IT and information systems, spanning infrastructure, business applications, data governance and cybersecurity.

Your mission will be to ensure reliable day-to-day operations while building the systems and organisation needed to support our growth towards 250 employees, five international subsidiaries, two production sites and research laboratories.

Your scope will cover corporate IT and internal operational environments, excluding product cloud infrastructure.

Combining hands‑on leadership with a strong understanding of business needs, you will help shape how our information systems support the company's development.

This role offers the opportunity to grow towards a Group position over approximately 18 months, depending on your contribution, demonstrated readiness and the company's evolving needs.

• Your key responsibilities
• IT strategy and governance: Define and own the Group's information systems roadmap.

Work with business leaders to prioritise projects and investments, clarify ownership and report on progress, service quality and key risks.

• Team leadership : Manage and develop the IT team, organise responsibilities and build the right balance of internal expertise, external providers and local support.
• IT operations and international support: Ensure reliable infrastructure and responsive user support across HQ and subsidiaries.

Oversee devices, identities, access management, networks, collaboration tools and internal cloud-hosted services, applying shared standards while accommodating local needs.

• Business applications and integration: Partner with Finance, HR, Procurement, Supply Chain, Production and R&D to translate operational needs into appropriate solutions.

Oversee application selection, integration and lifecycle management, ensuring clear ownership and coherent information flows.

• Production and laboratory IT: Work with Industrialisation, Engineering and Science teams to support equipment connectivity, dedicated workstations and experimental and production data environments.

Agree responsibilities for equipment interfaces, maintenance and changes, taking operational constraints into account.

• Cybersecurity and resilience: Lead the implementation of IT security policies, access controls, monitoring and incident response.

Maintain and test backup, restoration and disaster recovery arrangements, with recovery priorities agreed with the relevant teams.

• Data governance: Establish practical rules with business owners for data access, quality, storage, retention and sharing, in coordination with the relevant privacy and security stakeholders.
• Budget and supplier management: Own the IT budget, investment planning, contracts and licences. Assess costs, risks and expected benefits, and manage supplier performance.
• Support changes to systems and ways of working through communication, training and documentation.
• Your priorities for the first 12-18 months
• Establish a shared roadmap: Assess the existing infrastructure, applications and critical data flows, and agree a prioritised transformation plan with management and business owners.
• Structure scalable IT services: Formalise the service catalogue, support processes, onboarding and offboarding, and service indicators.

Define a consistent deployment and support model for subsidiaries, production sites and laboratories.

• Strengthen security and continuity: Advance device and network hardening, zero‑trust access principles and segmentation for sensitive activities.

Clarify the roadmap against relevant security requirements and frameworks, including GHI, NIS2 and ISO 27001, and test recovery capabilities.

• Simplify and connect the application landscape: Rationalise collaboration tools and priority business applications, improve integrations and reduce duplication.

Develop a sovereignty‑conscious, open source‑first approach where compatible with security, usability and operational requirements.
