What are the responsibilities and job description for the Sr. Staff Engineer, Photonics Design position at Ayar Labs?

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
