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
The pay range for this role is:
150,000 - 230,000 USD per year (Bay Area, CA)
