Analog IC Design Engineer, Tech Lead
Lightmatterindustry
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 architects and engineers to develop innovative high-speed analog transceiver solutions for next-generation optical and wireline communication systems.
Responsibilities
- Design high-performance and high-speed AMS circuits with a focus on transceivers and broadband circuits interfacing with silicon photonics elements
- Investigate and evaluate new Analog & Mixed-Signal circuit topologies with chip architects
- Lead the discussions with multi-functional teams (system, digital, analog, photonics) to create and drive block-level specifications, mixed-signal implementations, and behavioral modeling
- 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 performances of the circuits in the lab
- Mentor junior design engineers
Qualifications
- MS with 12+ years of industry experience, OR Ph.D with 10+ years of industry experience designing in either GHz-speed RF or GHz-speed broadband analog design
- Experience designing Analog-Front-End blocks for SerDes
- Experience and deep understanding of Tx/Rx equalization techniques and circuits
- Excellent understanding of CMOS device characteristics, noise, linearity, high-frequency circuit theory and design trade-offs
- Proven experience working with system and architecture teams to drive block-level and IP requirements
- Experience in Analog Mixed Signal circuit modeling and performance evaluation (e.g., SystemVerilog, Matlab, Python, VerilogAMS)
- Experience with 3D Electro-Magnetic (EM) simulation tools
- Prior experience in leading or mentoring junior design engineers
- Ability to work collaboratively with people across multiple functional areas
Preferred Qualifications
- Experience designing Analog-Front-End blocks for transceiver circuits such as trans-impedance amplifiers (TIA) and Tx Driver
- Experience interfacing with silicon photonic modulators (MZM, Ring)
- Hands-on design experience in advanced CMOS technologies, such as FinFET
- Successful track record in delivering analog/mixed-signal IPs with 1st-time success while meeting tight schedules
