Job summary

Quandela is seeking a proactive engineer to join the Source Production team in Île-de-France, focusing on precise fiber coupling for single-photon sources and robust pigtailing methods. The role collaborates with fabrication and characterization teams to improve reliability and production throughput.

You will contribute to process development, documentation, and quality metrics while working in a multi-disciplinary quantum optics environment that values precision and reproducibility.

Qualifications

• Engineering degree in optics, photonics, optomechanics, experimental physics or related field.
• Strong hands-on experience in optics and optical alignment.
• Experience with fiber coupling, fiber handling or fiber-based optical systems.
• Good understanding of photonic structures and optical components.
• Experience with cryogenic systems or low-temperature optical setups.
• Ability to work with high precision and follow established procedures.
• Good communication and reporting skills.
• Good level of English.

Responsibilities

• Perform high-precision fiber coupling between single-mode fibers and micropillars, with alignment precision below 100 nm.
• Fiber preparation and assembly steps: fiber cleaving, fiber gluing, mounting with ferrules and holders, fabrication of structures on fiber tips, anti-reflection coating treatment.
• Develop and improve methods to evaluate coupling and alignment quality through clear metrics.
• Cool down pigtailed sources and support the validation of the assembled devices.
• Perform optical characterization of quantum emitters using quantum optics techniques, including single-photon detection.
• Contribute to production procedures and reporting with other teams.
• Work closely with the fabrication and optical characterization teams.
• Contribute to productivity improvements and risk mitigation in the pigtailing process.
• Simulation experience is a plus.
