High Speed Analog Design Engineer

Lightmatter builds chips that enable extreme-scale artificial intelligence computing clusters. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems, and doing impactful work like building the world's first optical computers, consider joining the team at Lightmatter!

In this role, you will be a key member of the analog team architecting the world's first photonic computers. This is fundamentally an interdisciplinary team, and outside-the-box thinking is the daily norm. You will need both deep expertise in mixed-signal and analog design and breadth across other engineering disciplines, such as photonics and digital electronics, semiconductor device physics, thermal/packaging, and machine learning. The successful candidate will demonstrate an eagerness to refresh and grow their competency in these areas.

*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 (TIA, TX Driver) 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 performances of the circuits in the lab

Requirements

• MS with 3+ years of industry experience, OR Ph.D. with 5+ 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

• Experience with testing and validating high-speed analog/mixed-signal 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

Preferred Qualifications

• Knowledge of 3D Electro-Magnetic (EM) simulation tools is a plus

• Experience interfacing with silicon photonic Mach-Zehnder modulators is a plus

• Successful track record in delivering analog/mixed-signal IPs with 1st-time success while meeting tight schedules

• Ability to work collaboratively with people across multiple functional areas

Benefits

• Comprehensive Health Care Plan (Medical, Dental & Vision)

• 401k matching

• Life Insurance (Basic, Voluntary & AD&D)

• Generous Time Off (Vacation, Sick & Public Holidays)

• Paid Family Leave

• Short Term & Long Term Disability

• Training & Development

• Flexible, hybrid workplace model

• Stock Option Plan

• Commuter Benefit (pre-tax)

We offer competitive compensation. The base salary range for this role, inclusive of all US locations, is $130,000-$240,000. Your base salary will be determined based on location, experience, educational background, and market data.
