Job summary

Quandela’s Source Production team seeks a professional to advance fiber pigtailing for single-photon sources. You will develop and refine high-precision fiber coupling methods and work with the pigtail team to ensure reliable production.

The role requires a PhD or engineering degree in optics or related field, hands-on optics experience, and strong English; cryogenic setups and photonics knowledge are valued. On-site collaboration with fabrication and characterization teams is essential.

Qualifications

• PhD or engineering degree in optics, photonics, optomechanics, experimental physics or a 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

• Integrating micro-structure to the PIC waveguide edge coupling.
• Perform high-precision fiber coupling between single-mode fibers and individual micropillars, with alignment precision below 100 nm.
• 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 the development of reliable and reproducible production procedures.
• Write systematic reports and share production feedback 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.
