Analog IC Design Engineer, AMS

Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads.

Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter!

If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.

Lightmatter is (re)inventing the future of computing with light!

About this Role

Join a cutting-edge team at the forefront of silicon photonics and analog circuit design! As a member of the analog team, you’ll collaborate with our architects and engineers to develop innovative analog and mixed-signal (AMS) solutions for next-generation optical and wireline communication systems.

Responsibilities

• Design analog/mixed-signal (AMS) circuits used in control loops, such as data converters, amplifiers, drivers, comparators, bandgap, and more


• Support micro-architecture development with chip architects by conducting feasibility studies


• Collaborate with members of our design engineering teams (system, digital, analog, photonics/laser) to define electrical requirements


• Document design simulations and verifications towards formal design reviews


• Drive block-level floorplan, mask design views, and their reviews


• Run post-layout and mixed-signal top-level simulations to validate integration


• Define production and bench-level test plans


• Validate the performance of the circuits in the lab

Qualifications

• MS with 12+ years of relevant experience, OR Ph.D. with 9+ years of industry experience designing analog and mixed-signal circuits


• Solid understanding of CMOS device characteristics, noise, mismatch, linearity, and design trade-offs


• Experience with Cadence Design Environment


• Experience in testing analog circuits in a lab environment


• Ability to work collaboratively with people across multiple functional areas

Preferred Qualifications

• Experience interfacing with Silicon photonics (MZM, Ring) or laser IC is a plus


• Experience in chip top-level design is a plus
