Lightium, a leading-edge photonics startup, is looking for a skilled Photonics Metrology R&D Engineer to drive the development of new processes and modules for our innovative thin-film lithium niobate (TFLN) platform. This role offers a unique opportunity to contribute to the next generation of photonics solutions while collaborating with top academic institutions.
Position Summary
As a Photonics Metrology R&D Engineer, you will define, implement and execute wafer-level metrology techniques to advance our TFLN-based PIC platforms. Your contributions will be pivotal in continuing the innovation at the metrology level in state-of-the-art metrology lab, bringing our cutting-edge photonic technologies from concept to mass production.
Key Responsibilities
Technical:
Operate and maintain high-precision instruments, including scanning electron microscope (SEM), stylus profilometer, ellipsometer, and optical and confocal microscopes.
Thin-film characterization:
Analyze wafer-level data to evaluate film stress, uniformity, roughness, film thickness, refractive index, and defect analysis.
Quality:
Validation and qualification of metrology tools to ensure measurement accuracy, repeatability, and long-term system stability. Drive calibration control of Lightium's metrology tool park.
Supporting process optimization:
Provide metrology-driven feedback across deposition, etching, masking, and lithography workflows, thereby contributing to Lightium's roadmap-driven photonic device development.
Collaboration:
Work closely with the R&D teams from design, processing, fabrication to optical testing and characterization, contributing to cross-functional projects to advance our PIC technologies.
Documentation and Reporting:
Maintain thorough documentation of process development and report findings, as well as implement standard operating procedures (SOPs) for measurement protocols.
Innovation:
Stay up-to-date on the latest advancements in photonics, incorporating new metrology techniques and technologies into our R&D landscape.
What Our Ideal Candidate Brings
Educational Background:
An advanced degree in material science, physics, photonics, electrical engineering, or a related field.
Experience:
