Job summary

Lumentum develops the optical and photonic solutions powering AI, cloud and data centers, telecoms, and advanced manufacturing. This role centers on epitaxial growth for III/V devices with PhD-level expertise.

You will translate designs to growth recipes, coordinate internal and external fabrication, and drive high-yield processes while collaborating with device teams. You will work across the wafer process, design, and reliability teams, leveraging tools like Excel, JMP, Python, and MATLAB to

Qualifications

PhD degree in optoelectronics or other relevant major with industry experience is minimum requirement.

Responsibilities

Coordinate with device designers to develop the epitaxial growth recipes needed for the devices to meet performance requirements.
EPI design includes modeling design inputs such as layer thicknesses and compositions, doping profiles, active regions, growth conditions to outputs such as mode profiles, beam divergence and electrical resistance.
EPI designs must align with wafer processing and device design technology with high yield.
Translate designs into EPI growth recipes and interact with internal EPI growers or manage external vendors to execute the growths.
For each growth campaign review all calibration and EPI characterization data and feedback to growers or modify EPI designs as needed.
Work with device designers and wafer process integration teams to launch process runs and analyze critical data to feedback to EPI design.
