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 high-speed
transceiver design! As a member of the analog team, you’ll collaborate with our

solutions for next-generation optical and wireline communication systems.
- We are currently hiring for multiple levels for this role. Your level and
compensation will be determined by your experience, education, and location.
RESPONSIBILITIES
- Support micro-architecture development with chip architects by conducting
feasibility studies
- Collaborate with members of our design engineering teams (system, digital,
analog, photonics) to define electrical requirements
- Design analog/mixed-signal blocks with a focus on transceivers and broadband
circuits interfacing with silicon photonics elements
- 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 6+ years of industry experience, OR Ph.D. with 3+ years of industry
experience with a focus on optical or wireline transceiver design
- Experience designing Analog-Front-End blocks such as trans-impedance
amplifiers (TIA) and Tx Driver
- Experience with Tx/Rx equalization techniques and circuits
- Familiarity with SERDES architectures and implementations
- Solid understanding of CMOS device characteristics, noise, mismatch,
linearity, and design trade-offs
- Experience with Cadence Design Environment
- Ability to work collaboratively with people across multiple functional areas
Preferred Qualifications
- Knowledge of 3D Electro-Magnetic (EM) simulation tools is a plus
- Experience with testing and validating high-speed analog/mixed-signal
circuits
- Experience interfacing with silicon photonic modulators (MZM, Ring) is a plus
- Successful track record in delivering analog/mixed-signal IPs with 1st-time
success while meeting tight schedules
