About the role
We are seeking a highly technical, detail-oriented laser engineer to drive the development and validation of III-V semiconductor lasers and amplifiers. This role is ideal for someone with strong experience in laser validation for sensing applications. You will own the development and validation of III-V semiconductor laser components and laser systems against system requirements. You will also serve as a liaison for validating laser performance within a tightly integrated photonic sensor. In addition, you will support OSAT and foundry activities for III-V assembly and fabrication. Success in this role requires clear communication, strong execution, and attention to detail.
What you'll do
Own III-V R&D characterization of lasers, amplifiers, and heterogeneously integrated
III-V
and
Silicon Photonic
- subsystems. This includes characterization such as phase noise, linewidth, and RIN.
- Own III-V R&D test development and expand test coverage as needed for
- additional
- requirements. Troubleshoot and debug test setups and design issues,
- identifying
- and resolving challenges
- in a timely manner.
- Perform comprehensive characterization and data analysis to ensure III-V components meet system requirements.
- Perform simulations in Simulink or Python-equivalent environments to support device characterization.
- Support III-V layout and tape-out,
- participate
- in design reviews, and contribute to design
- methodology
- improvements.
- Collaborate with the silicon photonics (SiPh) team and operations team to hybrid-integrate III-V components with
SiPh
components.
Work closely with OSAT and foundry partners to drive the development of III-V components and resolve technical challenges
Support the transition of
key laser components from
R&D into high-volume manufacturing
