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 
• Opportunity to work on cutting-edge technologies with a highly cross-functional team
