Fiber Pigtailing Engineer (Master level)

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 🚀 About this position:Join Quandela’s Source Production team to work on the fiber pigtailing of single-photon sources.The role focuses on developing, improving and operating highly precise fiber coupling methods for photonic quantum devices.The role is part of the Source Production team, which currently includes 11 people across fabrication, fiber pigtailing and optical characterization. The role is part of the pigtail team, currently composed of one person, and works in close interaction with the fabrication and characterization teams.The objective is to improve the reliability, reproducibility and productivity of the pigtailing process, from prototype development to production-ready methods.Key responsibilitiesPerform high-precision fiber coupling between single-mode fibers and individual micropillars, with alignment precision below 100 nm Work on fiber preparation and assembly steps, including: fiber cleaving fiber gluing fiber 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 metricsCool down pigtailed sources and support the validation of the assembled devicesPerform optical characterization of quantum emitters using quantum optics techniques, including single-photon detectionContribute to the development of reliable and reproducible production proceduresWrite systematic reports and share production feedback with other teamsWork closely with the fabrication and optical characterization teamsContribute to productivity improvements and risk mitigation in the pigtailing processSimulation experience is a plus RequirementsDesired profileRequired Engineering degree in optics, photonics, optomechanics, experimental physics or a related fieldStrong hands-on experience in optics and optical alignmentExperience with fiber coupling, fiber handling or fiber-based optical systemsGood understanding of photonic structures and optical componentsExperience with cryogenic systems or low-temperature optical setupsAbility to work with high precision and follow established proceduresGood communication and reporting skillsGood level of EnglishNice to haveExperience with quantum emitters or single-photon sourcesSimulation experience is a plus Good balance between hands-on and simulation, ideally around 70% hands-on / 30% simulationSoft skillsVery precise and rigorousStrong respect for proceduresCreative when developing new methodsReliable and methodicalGood risk mitigation mindsetTeam playerHands-on and practicalBenefitsCompetitive salary, flexible based on your experience Profit-sharing & company savings plan100% health coverage (Alan)50% transport reimbursement or sustainable mobility bonusMeal vouchers (Swile), Gymlib fitness supportChildcare assistance & referral bonuses (€1,000–€2,000)What we offer: A meaningful role with real ownership, from day oneA team eager to collaborate and grow with youDaily exposure to the entire quantum stack — from high-level APIs to low-level firmware, and everything in between.
