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!
We are hiring a Photonics Layout & Design Intern to join our team. In this role, you will contribute to component and system photonics layout as well as photonics design and test. You will also interact with photonics architecture, design, and test teams to assist in the overall development of photonic systems, specifying, selecting, and qualifying the various components necessary.
Join a tight-knit team where each individual’s contributions directly influence the success of the company and product. You'll have the opportunity to build innovative laser solutions from the ground up and tackle groundbreaking challenges. Work with people who love to build and who thrive in diverse technical environments where great ideas are prioritized.
Responsibilities- Own photonics layout of the overall chip as well components
- Design high-performance photonics devices suitable for high-volume manufacturing
- Work with the photonics test team in defining requirements for device characterization, debug and validation
- Analyze characterization data to ensure the device/system meets the specifications
- Engage in problem solving and contributing with novel architectural ideas
- Pursuing PhD in Photonics or Optics
- Experience with code based GDS creation such as GDS Factory or similar
- Proficiency in layout, modeling, and data analysis in Python
- Experience with large scale layout, testing, and characterization of photonic devices

What We Do
Lightmatter is a startup photonics company that has pioneered a new paradigm in processor chip architecture that uses photons instead of electrons. Now the leader in the photonic AI compute “space race,” this new class of high performance semiconductors is the foundation of Lightmatter’s mission to enable the growth of computing, reduce harmful emissions associated with this growth, and democratize computing for all.
Lightmatter's technology accelerates critical operations in deep neural networks, using an array of programmable photonic elements fabricated alongside transistors in conventional computer chip fabrication processes. Our close-knit team of engineers has created an integrated photonics chip and ultra-high performance interconnect that is faster, more efficient, and cooler than anything else on earth (or anything ever experienced before) to power the next giant leaps in human progress.
