Sr. Staff Engineer, Analog/Mixed Signal Design
Location: San Jose (on-site)

As an Analog and Mixed Signal Design Engineer, you will design various blocks such as oscillators, high speed transmitters/receivers, biasing circuits, linear regulators, ADCs/DACs, and others. You will work as a part of a small IC design team in a dynamic startup environment. The ideal candidate is a hands-on self-starter who is able to develop design specifications based on input from colleagues, customers, and industry and who can effectively manage his or her own time to take projects to completion with limited supervision and guidance.


Key Responsibilities:
  • Architect and design high speed signal path for high bandwidth optical links
  • Work closely with optical and digital design teams to architect mixed-signal control loops
  • Design analog/mixed signal circuits such as oscillators, high speed transmitters/receivers, amplifiers, biasing circuits, linear regulators, ADCs/DACs, and others
  • Define, run, and automate sign-off verification simulations
  • Create design review and testing documentation
  • Perform post-silicon bring-up of circuits in lab

Required Qualifications:
  • M.S. or Ph.D. in Electrical Engineering
  • 6+ years of work experience in analog/mixed signal design
  • Experience designing high speed analog blocks such as PLLs, clock distribution and multi-phase generation, high swing transmit drivers, high speed receive analog front ends.
  • Proficient with Cadence design environment and mixed-signal simulation (ADE, Layout, Spectre)
  • Have experience designing in FinFet CMOS (7nm or below) at data rates of at least 50Gb/s and/or RF circuits operating at 25GHz or above

Preferred Qualifications:
  • Demonstrated experience in deploying SerDes into a high-volume product
  • A good understanding of high-speed design/layout considerations, such as parasitics, crosstalk isolation, supply and bias distribution, etc.
  • Able to develop adaptation/calibration algorithms for precision design
  • Experience with silicon bring-up, debug, and evaluation
  • Programming experience in Python and SKILL.
Salary range: $180,000 - $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.
