Company mission
Lightmatter's mission is to build an engine that will power discoveries, drive progress, and redefine what computers and human beings are capable of.
Role
Who you are
- 5+ years of industry experience, including at least one year using Altium Designer
- Experience interpreting datasheets and schematics to generate proper constraints in the layout design
- Knowledge of IPC, JEDEC, IEEE, and other electronic standards
- Experience designing high speed serial interfaces (25Gbps or higher) and the latest memory interfaces such as GDDR5/6
- Experience designing DC/DC converters for high efficiency and low noise
- Familiar with Product Lifecycle Management tools, e.g. Oracle Agile, Arena, or Omnify PLM with an understanding of BOM and ECO management
- Knowledge of common manufacturing processes
What the job involves
- As a PCB Layout Engineer, you will be responsible for delivering board and system solutions using Lightmatter’s innovative technology to create state of the art machine learning/artificial intelligence platforms
- You will work closely with our hardware teams, including mechanical, packaging, and IC engineering, to design and build leading edge system level products
- PCB layout of high-speed, high-density multi-layer printed circuit boards, 14-layers and up
- Create a constraint-driven routing methodology
- Develop and maintain a corporate library of component footprints
- Interface to outside PCB layout service bureaus when necessary
- Work with hardware engineers and PCB fab vendors to create stack-ups, obtain impedance specifications, and resolve technical issues during the PCB fabrication process
- Ensure the board layouts meet the latest Design For Manufacturability standards
- Create complete output packages including gerbers, fabrication and assembly drawings, odb++, IPC, and placement files
Our take
Neural networks and CPUs are vital to AI solutions, but manufacturers have largely failed to maintain innovation in recent years. Lightmatter solves this problem by offering a next-generation computing platform powered by photonics (light waves).
Lightmatter offers a forward-facing platform for AI-building that acts as an alternative to traditional solutions. It works by replacing wired CPUs with a combination of photonics and new algorithms. Lightmatter's solution is not only faster, but it is considerably more sustainable, and it has the potential to drive the next generation of AI development.
As of 2025, Lightmatter has raised $850 million across six funding rounds and grown to a staggering valuation of $4.4 billion, a testament to growing industry demand for faster, more effective AI-building solutions. Lightmatter currently has three products on the market - Envise, Passage, and Idiom - and is poised to take on the incumbent chiplet industry with a photonics-based alternative.
