Description

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

Responsibilities

Lead the development, characterization, and validation of III-V semiconductor lasers and amplifiers for photonic sensing applications. Collaborate with foundry partners and the silicon photonics team to integrate components and transition designs from R&D to high-volume manufacturing.
