Perform optical and electrical characterizations of thin-film lithium niobate (TFLN) photonic integrated circuits (PICs). This is the role for an operator performing high-quality characterizations for TFLN development and products with ability to implement development steps for advanced lab setups, including probe stations and test instrumentation. The engineer must ensure a full availability and interruption-free evaluation of PIC and PIC-modules.

Key responsibilities:

• Deliver high-precision performance data for PICs and optical modules enabling design validation, root cause analysis, and manufacturing yield improvement.
• Shorten design-to-validation cycle time through efficient setup automation and streamlined test methodologies.
• Enhance product performance and manufacturability by providing clear, data-driven recommendations to design and process teams.
• Oversee daily lab environment, ensuring high-quality, reproducible results.
• Ensure adherence to lab safety standards and equipment handling protocols.

Education: B.Sc. in optoelectronics, physics or a related field.
Experience: ≥1 years in photonic device characterization
