Sr Staff Engineer, Photonics Design

Location: San Jose (on-site)
As a photonics design engineer, you will push the envelope of bandwidth density, energy efficiency, and manufacturability of our silicon photonics optical I/O platform, removing the bottlenecks limiting next-generation AI and advanced compute architectures.
You will help define our product roadmap and drive development to meet aggressive customer requirements.


Essential functions
  • Design the high-performance integrated photonic components needed for an aggressive optical I/O product roadmap
  • Drive efforts at foundry and OSAT partners to overcome process limitations
  • Build data infrastructure: formulate and extend custom code base for layout, analysis, and automated checking
  • Enable next-generation architectures: target device-roadmap goals needed for high-impact product features
  • Drive PIC to meet system requirements in collaboration with experts in laser, packaging, firmware, and circuits to ensure product success
Required qualifications
  • PhD degree in Optical Engineering, Electrical Engineering, or a related field
  • 6+ years (research and commercial) experience developing electro-optic systems
  • Great programming skills; proficiency with Python, experience writing well-structured code and developing a code base as part of a team
  • Experience with Design Validation Testing and handoff to manufacturing
  • Solid understanding of photonic devices: couplers, photodetectors, electro-optic modulators, micro-ring resonators, gratings
  • Experienced with simulation and design tools for passive and active optical devices (e.g., FDTD, charge transport)
  • Experience successfully taking an opto-electronic product to market: design, debug and validation
Preferred qualifications
  • Experience with high-speed design and analysis of RF tests
  • Understanding of industry’s transition to co-packaged optics: drivers, pain points, and product differentiators
  • Experience with statistical analysis of test data, DOE methods
  • Familiar with electro-optic reliability modeling and testing
  • Hands-on experience with fiber optic test and electro-optic instruments: e.g., bit-error-rate testing, wafer-screening tests


Salary range: $170,000 - $223,000

About Ayar Labs:

At Ayar Labs we’re about to revolutionize computing by moving data with light. We’re unleashing processing power for artificial intelligence, high performance computing, cloud and telecommunications by removing the bottlenecks created by today’s electrical I/O -- making it possible to continue scaling computing system performance. Ayar Labs is the first to deliver an optical I/O solution that combines in-package optical I/O chiplets and multi-wavelength remote light sources to replace traditional electrical I/O. This silicon photonics-based I/O solution enables chips to communicate with each other from millimeters to kilometers, to deliver orders of magnitude improvements in latency, bandwidth density, and power consumption.
With our strong collaborations with industry leaders and government, our deep ties to MIT and UC Berkeley, and our commitment to hiring the best engineers in photonics and electronics, joining our team gives you the opportunity to collaborate with renowned experts on challenging, paradigm-shifting work.
We are passionate about delivering in-package optical I/O at scale, leveraging the strength of our patent portfolio and our team of leading interdisciplinary experts. We believe that deep cross-collaboration between teams facilitated by honest, open debate is the best way to drive innovation and achieve big wins. Join our team and experience the possibilities.
