Job description

Job Description

We are seeking a highly motivated Research Scientist to join our team to on developing Integrated Quantum Light Sources for Photonic Quantum Processors. The successful candidate will focus on the development of wafer-scale poling techniques and advanced characterization of thin-film lithium niobate (TFLN), with the goal of enabling high-quality quantum light source generation for scalable photonic quantum systems.

Responsibilities

• Design and implement automated control and data‑acquisition systems for poling processes, confocal‑based domain imaging, and fiber‑to‑chip coupling characterization.
• Establish high‑throughput workflows for wafer‑scale device screening, including evaluation of poling quality, optical loss, and coupling efficiency.
• Integrate and synchronize optical, electrical, and mechanical instrumentation into a coherent and robust automation framework.
• Optimize system performance in terms of measurement speed, reproducibility, and scalability for large‑area device evaluation.
• Translate fabrication variability into systematic testing and feedback strategies to improve device yield and performance.
• Collaborate closely with fabrication teams to support process development and device optimization for TFLN photonics.
• Mentor junior researchers and students, and contribute to project planning, reporting, and research dissemination (publications, patents, and presentations).

Requirements

• PhD in Photonics, Electrical Engineering, Applied Physics, or a related field.
• Strong background in integrated photonics, with preference for experience in lithium niobate (TFLN) or related platforms.
• Proven experience in laboratory automation, including instrument control, data acquisition, and system integration.
• Strong programming skills (e.g., Python, LabVIEW, or equivalent) for developing automated measurement and control systems.
• Hands‑on experience with optical characterization techniques (e.g., laser‑based measurements, fiber coupling, confocal microscopy).
• Familiarity with ferroelectric domain engineering, poling processes, or nonlinear/quantum photonic devices is highly advantageous.
