Job description

Quantum Hardware Engineering Intern - Stabilisation and Control (H1/2027) at Quandela, Massy, Île-de-France, France (remote). An intern-level full time position in the Products team, listed under hardware engineering.

Description of the Team/Project

You will join the QPU Prototyping team, which develops and integrates the optical systems at the heart of Quandela’s quantum processors, turning advanced R&D experiments into operational hardware. Your project will focus on developing active stabilisation and control methods to maintain QPU performance over extended periods. Working at the intersection of experimental quantum optics, instrumentation, automation and data analysis, you will help transform laboratory demonstrations into stable, reliable and operational QPU subsystems.

Education & Background

• Currently completing an M2 or final-year engineering degree in physics, photonics, optical engineering, quantum technologies, control engineering or a related field.
• Previous hands-on experience in experimental optics, quantum optics or laboratory instrumentation is desirable.

Languages

• Professional working proficiency in English.

What we also offer

A challenging and innovative work environment at the heart of quantum computing. A diverse and collaborative company culture. Opportunities for professional growth and skill development.

At Quandela, we believe that the strength of our team is the plurality of experiences, perspectives, and journeys. We are committed to building a respectful, inclusive, and welcoming work environment. All applications are welcome.

Responsibilities

• Characterise the physical mechanisms and environmental drifts that limit optical-system and QPU performance.
• Develop active feedback methods to stabilise relevant parameters, such as optical phase, polarisation, spectral alignment and timing.
• Select and integrate suitable sensors, actuators, control electronics and measurement equipment.
• Develop software for automated calibration, real-time monitoring, feedback control and experimental data acquisition.
• Optimise system performance and define appropriate metrics, measurement protocols and acceptance criteria.
• Assess long-term stability, robustness and reproducibility through extended experimental campaigns.
• Implement automated methods for detecting and recovering from performance degradation.
• Analyse experimental data, identify limiting factors and propose improvements to the optical and control architectures.
• Document the system and collaborate with other teams to support its transfer into an operational quantum processor.

Requirements

• Proficiency in Python for experimental automation, data acquisition and analysis.
• Familiarity with optical experiments, laboratory equipment and measurement techniques.
• Experience with software version control, particularly Git, is desirable.
• Rigorous and methodical approach to experimental work.
• Strong analytical and problem-solving skills.
• Ability to work independently while collaborating effectively within a multidisciplinary team.
• Clear written and verbal communication.
• Curiosity, initiative and attention to detail.

Benefits

• Swile Card (meal vouchers)
• 50% participation in transportation costs
• Possibility of remote work
• Internship Allowance between €1,200 and €1,400 per month
• 1,5 days off per month, cumulative
