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

In this role, you will be defining the SoC architecture for a ground-breaking platform that integrates our high performance silicon-photonics-based network fabric with a custom machine learning accelerator. You will also work closely with our software, hardware and photonics teams to define and optimize the features needed to accelerate the next generation of machine learning algorithms.

The SoC Architect will create a blueprint for a Passage-first compute solution. This cross-disciplinary project brings together our experts in Software, Photonics, Systems, Packaging, Networking, and SoC Design to solve key design challenges in building computing solutions with Passage across servers and racks.

Responsibilities

  • Define the SoC architecture for Lightmatter's next-gen product
  • Author, review, and validate architectural specifications
  • Actively collaborate with the hardware and software teams to perform trade-off analysis between power and performance for AI workloads on the proposed architecture
  • With other architects, engage in problem solving and contributing with novel architectural ideas

Requirements

  • PhD degree in Computer Science, Computer Engineering, or Electrical Engineering +8 years of industry experience, or MS degree +12 years of industry experience
  • 8+ years of experience in compute ASIC architecture with an emphasis on low-power design
  • 5+ years of experience with processor design, accelerators, networks, and/or memory hierarchies
  • Previous experience leading and collaborating in a cross-disciplinary team in a variety of fields
  • Previous experience in a fast-paced (startup) environment, with the ability to react to change
  • Experience influencing decisions in a matrix environment

Preferred Qualifications

  • Experience in leading a low-power architecture project from start to commercial volume chip production in an advanced node
  • Experience in post-silicon measurement with the goal of correlating with pre-silicon power forecast
  • Demonstrated technical innovations with impact on AI or high-performance computing
  • Demonstrated strong problem-solving skills in problems that do not have obvious solutions

We offer competitive compensation. The base salary range for this role determined based on location, experience, educational background, and market data.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Lightmatter’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.


Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
