Lightmatter is a photonic computer company redefining what computers and human beings are capable of by building the engines that will power discoveries and drive progress in a sustainable way. With modern human progress relying heavily on computers, the world has hit a dead end with traditional transistors and the prospect of constantly building data centers is an environmental nightmare. Lightmatter has created a solution in photonic computing: using photons instead of electrons to take advantage of their higher bandwidth. We build chips for artificial intelligence computing. Our architecture leverages unique properties of light to enable fast and efficient inference and training engines.

We are hiring a Digital Design Engineer to help develop an ASIC for the next-generation artificial intelligence computing architecture alongside a team of world-class scientists and engineers. If your passion is innovation, solving challenging technical problems and doing impactful work you should join our team and help build the world’s first optical computers!

In this job, you will work in close collaboration with computer architects, software engineers, verification engineers and physical design engineers to design innovative compute-accelerators that work with photonic technology to power the growing AI/ML workloads that customers want while keeping power low. This will be a great opportunity to define the next advance in computer architecture!

Responsibilities

• Develop microarchitecture design and RTL for advanced ML/AI accelerator ASICs/SoCs including advanced memory system and high-performance NoC.
• Understand and integrate silicon photonic communication and compute technology into digital accelerator design.
• Actively work with Architecture, Design Verification, Implementation, Photonic, Analog and Software teams to realize high performance, low power designs in advanced technology nodes.
• Create design specifications and documentation to facilitate collaboration with partner teams.
• Manage RTL implementation to achieve functionally correct, performant designs within project schedules by identifying, communicating and mitigating risks.

• Experience in ASIC design with multiple successful tape outs
• 12 years of related experience with a Bachelor’s degree; or 8 years and a Master’s degree in Electrical or Computer Engineering (or related fields)
