About the Role

As part of the continued growth of our activities and the deployment of our photonic Quantum Processing Units (QPUs) to international customers, we are looking for a Technical Support & Operations Engineer to join our team.

You will contribute to the operational monitoring of Quandela's QPUs and other hardware products deployed at customer sites , ensuring their proper operation and supporting maintenance activities, both remotely and on site.

Working at the interface between Quandela's technical teams and system users, you will develop a broad understanding of our products, particularly the interactions between hardware equipment and software control interfaces. You will perform initial technical investigations when issues arise and involve the relevant technical experts when required.

The role combines technical support, maintenance, field interventions, training and continuous improvement in a complex and international technological environment.

Internal training will provide you with the specific knowledge required to understand our technology and systems. No previous experience in quantum computing is required.

As our support and maintenance activities are still being structured, you will also contribute to improving our processes, tools and operational methods.

Your Key Responsibilities:

System operations & technical support

You will contribute to maintaining the operational performance and availability of QPUs and other hardware products deployed at customer sites.

• Monitor the operation and performance of installed systems.
• Analyse operational data and identify anomalies or performance degradation.
• Perform initial technical investigations to characterise issues and help determine the appropriate resolution path.
• Follow up on technical incidents and corrective actions with the relevant teams.
• Maintain accurate technical records of systems and interventions.
• Provide remote technical support to customers and trained personnel working on the systems.

Maintenance & customer-site interventions

You will contribute to the preparation and follow-up of preventive and corrective maintenance activities.
