Laser Tech lead Engineer

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
• Create detailed design documentation and technical specifications

Required Qualifications

• Master's or Ph.D. degree in Electrical Engineering, Applied Physics, or a related field, plus 3-5 years 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 reporting required for 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 in photonic sensing, coherent communications or lidar
• Familiarity with multi-chip packages, silicon photonics, and hybrid/heterogeneous integration of III-V components
• Ability to operate effectively in a startup environment with ambiguity, speed, and high ownership
• Additional experience with high-power semiconductor lasers and low-linewidth laser systems

Benefits (subject to location and local regulations)

• Competitive salary and equity
• Comprehensive medical, dental, and vision coverage
• 401(k) retirement plan
• Flexible vacation and time-off policy
• Collaborative, fast-paced, and inclusive work environment
