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 integratedIII-VandSilicon Photonicsubsystems. This includes characterization such as phase noise, linewidth, and RIN.

• Own III-V R&D test development and expand test coverage as needed foradditionalrequirements. Troubleshoot and debug test setups and design issues,identifyingand resolving challengesin 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,participatein design reviews, and contribute to designmethodologyimprovements.

• Collaborate with the silicon photonics (SiPh) team and operations team to hybrid-integrate III-V components withSiPhcomponents.

• Work closely with OSAT and foundry partners to drive the development of III-V components and resolve technical challenges

• Support the transition ofkey laser components fromR&D into high-volume manufacturing

• Create detailed design documentation and technical specifications

Required Qualifications

• Master's or Ph.D. degree in Electrical Engineering, Applied Physics, or a related field, plus3-5years of industry experience in III-V laser development or a related area

• Demonstrated experience in III-V laser development

• Familiarity with silicon photonics and passive optical components

• Strong familiarity with data reportingrequiredfor product development

• Ability to translate system requirements into laser requirements

• Strong familiarity with various lab equipment, such as lasers, photodetectors, modulators, optical amplifiers, oscilloscopes, spectrum analyzers, VNAs, motorized stages, and lock-in amplifiers

• Experience with optical system modeling of complex photonic components

• Experience developing software in Python, C, C++, or MATLAB

• Good understanding of coherent communications, signal integration, integrated optics, and semiconductor physics

• Strong written and verbal communication skills

• Ability to work independently as well as collaboratively in cross-functional teams.

Preferred Qualifications

• Deep understanding of high-power semiconductor lasers and amplifiers in optical systems

• Experience with new product transfer from R&D to operations teams

• Experience working with internal customers and external vendors (foundry, OSAT).

• Background inphotonic sensing, coherent communications or lidar

• Familiarity with multi-chip packages, silicon photonics, and hybrid/heterogeneous integration of III-V components

• Ability tooperateeffectively in a startup environment with ambiguity, speed, and high ownership
